About the Role

As an engineer on a small team with end-to-end product ownership, you'll own retrieval, tool orchestration, response generation, and production reliability for full-stack AI systems in hospitality operations and guest communication. This role focuses on agent reliability in handling real conversations, messy data, and third-party API failures.

Responsibilities

  • Design and build the response generation pipeline, including routers, orchestrators, and synthesizers.
  • Develop knowledge retrieval systems to ground responses in accurate data.
  • Build tool orchestration layers for reliable multi-step workflows with failure handling.
  • Create evaluation frameworks to measure quality and prevent regressions.
  • Implement observability and tracing for agent reasoning.
  • Design no-code controls for adjusting agent behavior.
  • Extend the system to support voice, including real-time transcription.
  • Optimize speed and cost through model routing, caching, and prompt refinement.
  • Own infrastructure, data pipelines, integrations, and API work.

Requirements

  • Proven track record shipping production systems used by real users.
  • Full-stack development capabilities.
  • Experience with reliable retrieval pipelines.
  • Pragmatic approach to model selection (frontier, fine-tuned, or simpler).
  • Strong evaluation discipline, measuring impact on real conversations.
  • Experience where work directly shapes the product.
