Senior Software Engineer

About the Role

Join an engineering team building AI software for hospitality operations. You will own full-stack components of an AI system that handles guest requests, from understanding intent and retrieving relevant information to coordinating tools and generating responses.

What You'll Do

• Design and build systems that classify guest requests, assemble context, select tools, and decide when to respond or escalate.

• Develop retrieval pipelines that ground responses in accurate and current customer information.

• Build reliable orchestration for multi-step workflows, including handling third-party API failures during conversations.

• Create evaluation frameworks to assess response quality and catch regressions before release.

• Implement observability and tracing that help support teams understand system behavior.

• Build controls that let non-technical teams adjust agent behavior without writing code.

• Extend agent capabilities to voice conversations with real-time transcription and tool use.

• Improve performance and cost through model routing, caching, and prompt refinement.

• Contribute to infrastructure, data pipelines, integrations, and APIs.

What We're Looking For

• At least 5 years of professional software engineering experience, including 3 or more years building production systems used by real people.

• Experience designing and debugging production AI or ML systems, including retrieval pipelines, prompt engineering, or model orchestration.

• Proficiency across multiple areas of the stack, such as backend, frontend, infrastructure, or data pipelines.

• Experience building and evaluating retrieval systems, multi-step workflows, and production observability or evaluation tools.

• Proficiency in a backend language such as Python, Go, Rust, Java, or a similar language, plus experience integrating third-party APIs.

• Strong judgment in selecting AI models and measuring system quality, reliability, latency, and cost.
