Job summary

Marriott is seeking a Director of AI Application Engineering to own the engineering of AI applications and agent systems across a portfolio of enterprise use cases. You will lead a group of forward deployed engineers, set the architecture, and stay hands on in code, guiding multi-system integrations with vendor teams and governance across production and post-production stages.

Reporting to the Senior Director, AI Engineering, you will drive architectural decisions, ensure quality, and mentor

Qualifications

• 8+ years in software engineering, including 3+ years building AI or machine learning applications, enterprise integrations, or platform services; or 6+ years with a Master's degree.
• Production grade Python and/or TypeScript; Rust is a plus
• Hands on LLM application development: agent design, tool calling, prompt engineering, retrieval, and evaluation

• Lead forward deployed engineers delivering AI applications and agents for a business vertical, holding the technical bar from intake through production handoff
• Design and build agent systems, tool and API integrations, and retrieval pipelines on the enterprise AI platform stack, using vendor SDKs and agent development kits
• Own architecture decisions for your portfolio and carry them through the enterprise governance gates, including agent tier classification, security engagement review, and architecture review
• Direct vendor and systems integrator engineering teams delivering alongside your own, setting the design and holding the quality line
• Stand up evaluation and monitoring for everything you ship, so agent quality is measured rather than asserted
• Contribute working patterns, SDK modules, and reference implementations back to the shared library after every build, and retire the ones that stop earning their place
• Build handoff packages, including runbooks, dashboards, and documentation, that let business and platform partners own solutions long term
• Mentor engineers across the function and set architectural guardrails others can follow without you in the room
