Senior Software Dev Engineer - AI Agents
Reporting to the head of this team, your main responsibilities will be:
- Agent architecture. Redesign the state machine for multi-turn, stateful conversations, covering position tracking, step confirmation logic where delivered is not the same as confirmed, prevention of premature advancement, back-navigation and re-anchor patterns.
- Reasoning and routing. Refactor the reasoning pipeline, covering separation of reasoning from speech, confidence gating, fallback and clarification routing, and removal of advance-only defaults.
- Retrieval and RAG. Improve retrieval quality through embedding pipeline clean-up, hybrid search, reranking using semantic and cross-encoder methods, and separation of metadata lookup from semantic search paths.
- Multilingual architecture. Evaluate and implement a multilingual solution across the full pipeline, covering translation accuracy, voice recognition for non-native speakers and cross-lingual retrieval.
- Evaluation harness.



Build and maintain an offline agent evaluation framework covering human versus agent answer parity, flow success rate, grounding and hallucination detection, and session-level trace analysis. Define and instrument the pilot quality gates.
- Voice and speech to text. Work with real-time speech to text at the agent layer, covering mishear recovery, low-confidence input handling, and accent and dialect robustness.
- Observability. Instrument agent traces for latency, cost per turn, tool selection accuracy and session quality.
