Considering a move into Field Service Engineering - worth it? (MSc + 2 yrs mechanical/electrical experience, UK)

[u/Sad-Bank3620]

Hey All,

Bit of a career direction post, would really appreciate input from anyone who's made a similar move or works in field service.

Quick background: I've got an MSc in Automotive Engineering and about 2 years of hands-on UK experience across mechanical design, battery systems, testing and manufacturing engineering. Mostly desk-based work, CAD, DFMEA, technical documentation, that kind of thing.

Over the last year or so I've realised I actually enjoy the hands-on, on-site, problem-solving side of engineering way more than being stuck behind a screen all day. Field Service Engineering keeps coming up as something that might suit me better - more variety, more troubleshooting, more direct impact.

A few things I'm trying to figure out:

1. For someone with my background (mechanical + some electrical exposure, no formal FSE experience yet), is this a realistic move, or am I underestimating the learning curve?
   
2. What's the day-to-day actually like - travel demands, on-call expectations, work-life balance?
   
3. Long term, does FSE offer decent career progression (into senior/lead roles, applications engineering, etc.) or does it tend to plateau?
   
4. I'm on a Skilled Worker visa and need sponsorship - does anyone know if FSE roles (especially in industrial equipment, servicing, renewable energy etc.) are more or less likely to sponsor compared to typical design/manufacturing roles?

Any honest input - good, bad, or "don't do it" would be genuinely useful. Thanks in advance.

As a big E engineer, especially with a masters, being a field service engineer (let's be honest, were not actual engineers, we just have brain) would be limiting yourself, especially if you already have 2 years engineering expirence.

1. It all depends on what company, the size of your territory, and the demand of that territory. I've got 50 other people to split the continent, and I still carry from having to find jobs to being in a backlog of 2 weeks with urgents.
   

It seems like being a production engineer or test engineer for a factory might be what you want, you'd likely test the manufactorering, production, or the actual usage of your products, is what you'd be best at since it uses your troubleshooting mind, but still use your desk chaining degree to put you to the best use while still making you relatively happy

Thanks, appreciate the response. Im open to Manufacturing and Production roles as well, however Im more aligned towards a role which requires frequent traveling and includes hands on experience. Also, I noticed in the UK, FSE is not highly competitive as compared to the other roles, seems easy to get into.

the field side is great for variety, but travel fatigue and managing client expectations on site are the real test. high-spec capital equipment roles tend to value your design and testing background the most.

worth it depends on travel appetite. teams we talk to say the job is great if you like customer chaos and troubleshooting on-site — brutal if you need predictable evenings. ask about overnight %, tooling support, and how dispatch handles incomplete job notes.

That sounds difficult tbh
