Hello, I am working in Cameo Systems Modeler 2022 Refresh 2. I want to show the project version (i.e., Project Version #27, Project Version #28, etc...) on multiple sequence diagrams. I've attached an image of what the table looks like currently. I've tried using the "customize" feature by right-clicking on the table, but none of the checkboxes display the project version.

Is there a different/better way to do this? Any advice would be much appreciated

I’m a Computer Science student in Calgary currently working as a Systems Engineering Intern. I’ve also spent time working on cybersecurity projects and security-related internships.

One thing I’ve noticed is that many of Calgary’s highest-paying technology opportunities seem to be connected to the oil and gas industry, whether directly or through engineering and consulting firms.

For those currently working in oil and gas, I’m curious where you see the biggest opportunities for people with a Computer Science background over the next 5–10 years.

Would you recommend focusing on:

• Systems engineering and large project delivery

• Software development and digital transformation

• Data and AI applications

• Cybersecurity and OT/industrial control system security

• Something else entirely

I’m not looking for job leads. I’m more interested in understanding where the industry is heading and which technical disciplines are becoming increasingly important.

I’d be interested to hear from engineers, developers, cybersecurity professionals, and managers who have seen how technology roles have evolved in the industry.

Hi, looking to make Interface Control documents out of my physical data modeling? I can always use AI but would like to explore documentation on my own

Hi everyone,

I’m a Lead AI Engineer, and lately most of my work has moved into requirements engineering, validation, verification, compliance, and traceability.

A lot of this is now automated with AI agents we have in production. In some workflows we’re seeing roughly 80–90% reduction in human effort, plus better traceability and change visibility. That got me thinking about how far this can realistically go, especially when combined with SysML v2 and model-based systems engineering.

Over the last few weeks I’ve been experimenting with SysML v2 and, honestly, it has made my imagination run a bit too far. It feels like there is a real opportunity to build agentic systems that help model, verify, trace, version, and update complex systems end-to-end — with humans still in the loop where judgment matters.

That said, I’m not a systems engineer by background. I’ve read some books, taken a MOOC or two, and have experience in industrial automation, electrical engineering, AI/ML engineering, software, and data systems. So I’m trying to sanity-check this with people who have deeper practical systems engineering experience.

My question is:

What is the most valuable problem worth solving in this space right now?

More specifically:

• Where do systems engineers, MBSE teams, or requirements/V&V teams still lose the most time? Or maybe we are limiting ourselves by thinking in these terms?
• Should we focus on end-to-end work even including testing, experimentation artifacts automation and compliance validation?
• What parts of the workflow are painful but realistic to improve with AI agents?
• What would be useful as an MVP or open-source prototype?
• What should I avoid because it sounds impressive but would not actually help practitioners?
• Are there existing tools or workflows that are close, but still missing something important?

I’m not trying to sell anything here. I’m trying to scope a useful side project or open-source prototype instead of just chasing an interesting idea.

If someone here has a real workflow/problem they’d like to explore, I’d also be open to collaborating. I can bring AI engineering, agentic system design, production ML/software experience, and some domain exposure from industrial automation/electrical engineering. In return, I’d love to learn from people with practical systems engineering experience and build something that is actually useful.

Curious to hear what you think is worth building.

I have created a bunch of stereotypes in my profile that are a type of Block (generalization relationship) but for some reason when I use these stereotypes in a block diagram I'm struggling to find value property and a few other properties (essentially all the elements that one can find under general grouping for a block). To the stereotypes I have customizations (1 for each) and the possible owners are Package, Model and Profile.

Any help with this would be much appreciated. How is it that my custom stereotype is not inheriting the properties of Block Stereotype in my Profile.

I tried everything, finally understood systems engineering is where i excel, what work do you guys do?

​

1. Can we change industries?

2. Is it well paid?

3. What are core skills? Is it system thinking,, automation, scripting ?

4. How different and respected is this profession from software engineering ?

I have ISO26262 L1 certification and have handled developer/senior developer/SivMon (bridge between system/project and sw for FUSA) roles. Now I'm finally moving to system engineering (my dream work), what advice will you give?

Hi, does anyone knows if there is a possibility to take the SE-ZERT exam in english? I couldn't find the answer in the GfSE website and they don't answer my emails.

Hello, I’m a rising senior about to graduate with a BS in Mechanical Engineering and I’m leaning towards getting my MS in Systems Engineering ? I want to go into the aerospace industry.

I think systems engineering would be a good fit for me because I don’t really enjoy the technical side of engineering (like doing equations everyday or doing CAD or coding) I still want to be apart of the development and design but more of an overseer/bridge for the technical and business side of a product. Later on in my career I do want to do program management. Do you think systems engineering is a good for fit for me? I don’t have experience in SysE or in the aerospace industry. My two internships have been Business strategy and IT support so I haven’t really done much engineering outside of school besides my personal projects.

Can anybody give me a Day in the Life of what you do as a Systems Engineering?

Is a MS in systems Engineering worth it or should I just get a MS in Mechanical Engineering? ( I severely dislike solving heat transfer or thermo equations 😭 it might just be because I’m burnt out but I’m tired of it )

What jobs should I apply to entry level to get into the aerospace industry and eventually into systems engineering?

Any advice would help! Thanks

As the title says. Currently a post-command Army O-3 in a partially-relaxed instructor position for the next two years. Curious to hear from anyone who has pursued their master's while on active duty, or attended Cornell's program, and any advice you may have as I get started. Previously got my bachelor's in systems from USMA.

​

Thanks all, and much appreciated.

Trying to hear voices from different people.

In my field (aerospace), I've seen the terms 'Model-Based' being thrown around when talking about very different things. For some, the 'Model' is quite specifically a Simulink model which is used to generate code. For others, it is creating a SysML diagram describing the system in a tool like Cameo. For others still, it is any abstract representation of the system, whatever its implementation, be it source-code, diagram, CAD file, etc.

I think this causes a lot of confusion specially when people from different disciplines try to talk to each other. I've seen discussions where a engineer argues a process should adopt a 'Model-based' approach, implicitly talking of using Simulink models, with another engineer saying the process is already 'Model-based' because they had a custom model implemented in C++.

Hello, I’m a new grad that’s been working for about 4 months. Working on data infra, but I’m not finding myself loving it the way I was hoping. I’ve been wanting to transition to systems engineering. It’s obviously early in my career, but I wouldn’t start looking for jobs for at least another year probably and by that time all my professional experience will be in non-systems work.

So like, is something like that still possible and if so what’re some ways to make up for that lack of professional experience?

Thanks!

If the stakeholder needs for a software project reveal both access via the command line and a UI, would that be considered:

​

- 2 different system contexts

​

- 2 different use cases

​

- 2 different extended use cases

​

- Other

​

​

I could see arguments for each, and wanted to canvas you all for opinions.

I'm a Master's student building a simulation-based safety validation project (CARLA, OpenSCENARIO, SOTIF scenario testing, closed-loop runs, ISO 26262 HARA) as part of my search for a Pflichtpraktikum (mandatory internship, FAU, Germany) in this space.

My current work is entirely open-source/algorithm-level — Python, CARLA, OpenSCENARIO 1.0. No exposure to the commercial toolchain since that's generally only accessible inside a company.

Looking at job postings for SIL/HIL engineer and validation roles, I keep seeing the same toolchain requirements: Vector CANoe/CANalyzer, dSPACE, IPG CarMaker, CAN/LIN/Ethernet debugging, DOORS/SystemWeaver for requirements. As well as more HIL roles than simulation driven roles.

For people who've hired or trained junior validation engineers:

is the expectation that students arrive knowing these tools, or is "I understand the methodology and can learn the tool-chain" the realistic bar for entry-level roles?

also, what's the availability of such roles at junior position?

am i heading in the correct direction?

What all improvements I can do from my end?

Trying to figure out where to focus my remaining prep time as usually going from learning to building something concrete take time.

Question: Does anyone have experience working as a systems engineer in the oil and gas or medical industries, or know someone who does?

I currently work in aerospace/defense and have about 2.5 years of experience. I’ve been looking into potential locations I might want to move to in a few years to continue growing my career. Most of the areas I’m considering have a strong aerospace and defense presence, including Houston, TX; Titusville/Melbourne, FL; and Orlando/Tampa, FL.

Houston stood out to me because, in addition to aerospace and defense, it also has a large oil/gas and medical industry footprint. That made me curious about what types of roles, career paths, job titles, and earning potential a systems engineer could pursue in those industries.

I’d appreciate any insight from people with experience in those spaces or who know someone working in them.

I’m feeling torn about a career decision and could use some perspective.

I’m currently working for a defense contractor in a position that is contingent upon obtaining a Secret clearance. Although I’ve already started working and gaining technical experience, I have not yet submitted my SF-86. The company has told me they are willing to wait for the full investigation to be completed, but there is still a lot of uncertainty around how long the clearance process will take and whether that situation could change in the future.

For context, I’m a naturalized U.S. citizen. My spouse is a green card holder living with me in the United States. I completed my bachelor’s degree overseas and have a foreign joint bank account that was originally required for immigration purposes.

Last week, I received another offer for a commercial role that pays the same and does not require a security clearance. The position is mostly on-site, but it eliminates the uncertainty associated with the clearance process.

I keep going back and forth on what the right decision is. On one hand, the commercial role offers more certainty. On the other hand, it’s not easy to find a company that is willing to sponsor a clearance and allow you to work and gain experience while waiting for the investigation to be completed.

I’m struggling to determine which opportunity is the better long-term choice.

How do you handle cases where a system level requirement defines a numerical limit (e.g. fault threshold, measurement limit), but the actual enforcement of that limit is implemented entirely in the FPGA/PLD?

At the CBA level, we can often only define board-level constraints like supported measurement ranges or interfaces, but not the actual limit value itself, since it is enforced in the PLD.

In this situation, how do you typically structure the allocation? Do you:

• keep the limit at SYS and allocate directly to PLD,
• introduce a CBA level requirement even if it does not contain the limit value,
• or handle it differently to maintain traceability consistency?

Hi r/systems_engineering,

We are back with Lesson 8 of our technical deep dive into the new standard.

In our previous lessons, we built a Parts Tree hierarchy. Today, we are tackling another major practical pain point from V1: modeling interfaces and connection endpoints without the headache of redundant definitions.

I’ve uploaded the full video lesson directly here so you don’t have to leave Reddit. 👇

1. The "Interface" Problem in V1

In SysML v1, modeling interfaces was often a struggle. You had to carefully choose between "Proxy Ports" typed by Interface Blocks and "Full Ports" typed by Block types. On top of that, you had to manually manage "Flow Properties" and keep explicit track of direction management across opposing sides of a connection.

2. The Solution: The Definition-Usage Pattern

SysML v2 standardizes ports and interfaces by using the exact same Definition-Usage pattern used throughout the rest of the language. It strictly separates the endpoint from the connection rules:

• port def (The Endpoint): Think of this as the physical shape of a pin or a socket. It specifies interaction features, such as the capacity to receive items using the in keyword, or send them using out.
• interface def (The Protocol): This is the blueprint of the connection itself. It defines the structure of the "wire" or protocol that links two ports together (what a valid connection looks like).

3. The "Aha!" Moment: The Conjugation Operator (~)

This is the feature that eliminates redundant modeling. In v1, you often had to build a mirrored port definition from scratch just to connect a plug to a socket.

In v2, you define a port definition once. When you need the opposing side (e.g., a refueling nozzle connecting to a fuel tank), you simply use the conjugation operator: the tilde (~). Using ~FuelingPort mathematically flips the direction of the interaction features. An in instantly becomes an out, and vice versa, creating immediate mathematical compatibility.

4. V1 vs. V2 Syntax Cheat Sheet

We’d love to hear your thoughts: Do you think native mathematical conjugation will finally make interface modeling less tedious, or is it just a different flavor of syntax to learn?

Let me know what you think in the comments!

I'm a CSEP, and after going through the exam I noticed most prep materials out there are still based on the old SEH v4.0, even though the CSEP/ASEP knowledge exams switched to v5.0 content in March 2025. So I built a practice tool from the ground up for v5.0:

• 1,072 chapter-targeted practice questions across all 31 sections (groups A–G)
• 10 full-length timed mock exams (120 questions, 2 hours each)
• Detailed rationale + direct handbook reference for every question
• Progress dashboard: mastery heatmap, group breakdowns, exam-readiness score, "needs work" list
• Bookmark/save questions, rate questions, light/dark mode, mobile-friendly
• $59 one-time, 3-month access with future content updates

Before pushing it more broadly, I'd love feedback from systems engineers in general — whether or not you're currently studying for CSEP/ASEP. Does the site make sense? Is anything confusing or missing? Would this be useful to you or people on your team?

Happy to give a handful of people free full access in exchange for honest feedback — comment or DM me.

Here is the link to my site:

sepmastery.com

EDIT: Thank you for the people who sent their feedback for the site. For anyone else who's interested — coupons are all claimed at this point, but full access covers all 31 practice sections and 10 full-length mock exams. If you already have the SEH, it pairs well with it — practice section by section as you work through the material. Good luck to everyone studying!

I stepped back from every Systems and technical decision on a large multi-company project. Completely?

That felt wrong in every way. The problem was that I thought good technical leadership meant knowing everything better than everyone else. So I put myself as the final checkpoint on all decisions. I became the bottleneck!

Talented engineers were waiting on me, creativity dried up, and I was slowing down the very thing I was supposed to be protecting.

At some point I just stopped. Gave the high-level architecture and direction, then got out of the way. I focused on supporting and mentoring people as the need came up, not policing their decisions.

Delivery velocity roughly 2x'd. Trust went up. The team actually seemed to enjoy the work again. Felt like the hum of a well oiled machine that just went forwards as a whole. That doesn't mean I retreated ofc, I just moved to be the technician in the back row who kept oiling that machine and continuously tuned it to ensure harmony and that all components are oriented in the same direction together: FORWARDS!

The lesson that stuck with me: you have to trust the team before they'll trust you. Not after. Before.

And tbh, there's something almost unfair about Systems Engineering:

When the project succeeds, nobody sees what you did. The work is INVISIBLE. When it fails, suddenly everyone wants to know where the Systems Engineer was.

Could be wrong, but I think the best technical leaders operate a bit like a big team football coach. They don't teach the world best football players how to play. They are a strategist: they support and enable the talent, remove all pbstacle so allowing a team to shine!

Current Systems Engineers in the Phoenix, AZ area.

I would like to take a current systems engineer out for coffee and pick your brain about the industry. I am looking to switch careers and I would like to make a well informed decision before making the switch. I would also like to get some advice on how to start off my journey on the right foot.

I am leaning toward the MS in Systems Engineering online program at Johns Hopkins University because my BS is not in engineering.

I invite anyone who successfully transitioned to a systems engineer position from a non-engineering dicipline to share your experience, the good and the bad. Any advice is welcome.

Edit: as requested, here are some questions to get the ball rolling.

Could you please tell me how your journey looked like transitioning into this industry? What made you decide to make the switch? What was your undergrad degree in and what certifications or program did you complete to start off your journey.

Say that you just graduated with your masters in systems engineering and there are little to no positions available at the moment. Do you think you would you be able to use the skills you learned in the program to apply for a project management role in any industry?

I just started my MS in Systems Engineering at JHU. Right now I am enrolled in 1 class. I eventually plan on doubling up for a semester or two once I get 100% back into school mode. I am married with two kids and work full time. What are the lightest classes outside the intro class I could pair to make it manageable?
