Senior Software Engineer

ABOUT THE ROLE Join an engineering team building AI software for hospitality operations. You will own full-stack components of systems that understand guest requests, retrieve relevant information, and carry out workflows, helping make automated support reliable and useful. WHAT YOU'LL DO - Build response generation pipelines that classify requests, assemble context, choose tools, and determine when to respond or escalate. - Develop retrieval systems that ground responses in accurate, current information from real-world customer data. - Create orchestration layers for multi-step workflows, including robust handling of third-party API failures. - Build evaluation frameworks using real conversations to measure quality and catch regressions before release. - Implement observability and tracing that help support teams understand system behavior. - Develop controls and interfaces that let non-technical teams adjust agent behavior. - Extend capabilities to voice conversations, including real-time transcription and tool use. - Improve speed and cost through model selection, caching, and prompt optimization, while contributing to infrastructure, data pipelines, integrations, and APIs. WHAT WE'RE LOOKING FOR - At least 3 years of experience building and shipping production systems that real users depend on. - Production experience with AI or machine learning systems, including retrieval pipelines, prompt engineering, or model orchestration. - Experience building and evaluating retrieval systems, such as knowledge bases, ranking, context validation, or semantic search. - Background designing multi-step workflows, tool orchestration, or function-calling systems, and integrating third-party APIs with production failure handling. - Proficiency in a backend language such as Python, Go, Rust, or Java, with experience across multiple areas of the stack. - Experience with evaluation methods and observability or debugging for complex systems; real-time applications, voice systems, user-facing controls, or cost and latency optimization are also relevant.
