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.
