Junior AI Engineer (Voice Agents)

About the Role

You will help scale our Voice AI Agent (telephony + STT + LLM + TTS) into an enterprise-grade product. This includes building real-time speech / LLM pipelines, barge-in and human takeover flows, data loops for model improvement, and natural interruption handling.

What You’ll Do

Implement and tune real-time STT / ASR and TTS pipelines.

Orchestrate LLM-driven conversations : prompting, function calling, dialog state, and context handling.

Build barge-in logic and reliable human handoff signals.

Create datasets for training : recordings, redaction, labeling, metadata; enable search and retrieval.

Optimize latency, accuracy, turn-taking, and cost.

Add guardrails, fallbacks, and basic A / B experimentation.

Required Skills

Programming : Python or Node.js; modular code, async handling.

APIs & Events : REST, webhooks, retries, idempotency.

Speech / LLM : Using STT / TTS SDKs or streaming APIs; prompt and function-calling basics.

Data : Basic SQL; schema design for transcripts; understanding embeddings / vector search concepts.

Cloud (AWS preferred) : S3, Lambda or equivalent services, CloudWatch.

Git & CI : Branching, PRs, basic pipelines.

Nice to Have
