# Founding Engineer - Voice AI

We’re building self-healing voice agents for enterprise customer support within ixigo. The system has to know when it’s failing, why it’s failing, and how to fix itself before a human notices. This fellowship sits at the intelligence layer behind that work. We need a founding engineer to own the voice AI product end to end: the cascaded pipeline that turns a phone call into a real-time conversation. This is not a research role and not a generic backend role. It is the person who understands, at the millisecond level, why a voice agent feels slow, where the latency actually lives across the STT, LLM, and TTS legs, and how to claw it back without breaking conversation quality. You will have access to real production call traces and a live traffic testing ground from day one. Decisions you make ship to real customer-facing calls within days, not quarters. What you'll own The end-to-end latency budget across the cascaded pipeline (STT finalization, LLM prefill and generation, TTS time-to-first-byte), with a target of sub-1-second end-to-end response time Diagnosing and fixing cross-cutting bottlenecks that touch multiple pipeline legs at once, for example, prompt size and cache-hit r
