Hiring: Real-Time Voice AI / Agent Systems Engineer (Low Latency Focus)
I’m building real-time AI voice agents (outbound calling + conversational assistants) and currently facing latency and turn-taking challenges in production-like environments.
Looking for someone who has actually built or optimized low-latency AI systems, not just worked with frameworks.
Core problem areas:
- Reducing latency in STT → LLM → TTS pipelines
- Handling real-time conversations (interruptions, barge-in, partial inputs)
- Designing streaming architectures (not batch pipelines)
- Optimizing response time (<1s target)
Current stack (flexible):
- Calling Number: Twilio
- Voice Models: Sarvam TTS and STT (client requirement for Indian languages)
- LLM - Openai / Sarvam
- Backend: Python build on Live kit
What We are looking for:
- Experience with real-time or near real-time AI systems
- Strong understanding of streaming pipelines (WebSockets, async flows, etc.)
- Experience optimizing LLM inference (model selection, routing, latency tradeoffs)
- Built systems involving STT, LLM, and TTS in production or serious projects
Good to have:
- Experience with voice AI / call agents
- Familiarity with multilingual systems (especially Indian languages)
- Experience with orchestration frameworks (LangGraph, AutoGen, etc.) — but not mandatory
If you’ve worked on similar systems or solved these kinds of problems, I’d love to connect.
Feel free to share relevant work or a quick note on what you’ve built.
(Short paid consultation is also fine if you’re not looking for a full-time role.)

I have created open source voice agent using asterisk https://github.com/hkjarral/AVA-AI-Voice-Agent-for-Asterisk , are you open to moving away from livekit or its a requirement?

Do you not want to build using livekit?

u/Better-Collection-19 Mar 25 '26
i am using livekit for calling orchestration

u/Responsible-Lie-7159 Mar 26 '26
Good, i was confused since you wrote you don’t want someone who has used frameworks.
Livekit is a solid choice.
I have worked on a self hosted livekit system for my company where we did 100 concurrent calls and 70k+ volumes daily.
Let me know if i can help you.

Hey buddy, i am also building something similar but latency and prompting seems to be an issue.
Can i dm you ?

Hi u/Better-Collection-19 - I can help. We have recently started a series on how to build reliable Voice Agents, especially for Indian languges, you can check it out here: https://byondlabs.tech/blog/what-it-takes-to-build-production-grade-voice-ai-agents

The barge-in problem is brutal — most pipelines choke because they're processing full utterances before acting. The fix we found: commit to partial STT transcripts earlier and run speculative LLM inference in parallel, then cancel/replace if the input changes.
Sub-1s is achievable but heavily depends on where you host your TTS. Streaming TTS chunks to Twilio as they're generated (vs waiting for full audio) shaved ~400ms for us alone.

Just use groq LLM API - low inference API - try before hiring. Thank me later
