We embed forward deployed AI engineers with teams across the enterprise, carry the company's highest priority AI use cases from intake through production, and turn each delivery into reusable patterns, SDKs, and reference architectures that make the next one faster.\nThe Role\nAs Director, AI Application Engineering you own the engineering of AI applications and agent systems across a portfolio of enterprise use cases. You lead a group of forward deployed engineers, set the architecture, and stay hands on in the code. Your portfolio carries the hardest engagements: multi system integrations, vendor engineering teams delivering alongside us, and decisions that set precedent for the rest of the AI program. You work across build, consult, advise, and monitor engagements at the same time, and you are accountable both for what reaches production and for what happens to it afterward. Reports to the Senior Director, AI Engineering.\nKey Responsibilities\nLead forward deployed engineers delivering AI applications and agents for a business vertical, holding the technical bar from intake through production handoff \nDesign and build agent systems, tool and API integrations, and retrieval pipelines on the enterprise AI platform stack, using vendor SDKs and agent development kits \nOwn architecture decisions for your portfolio and carry them through the enterprise governance gates, including agent tier classification, security engagement review, and architecture review \nDirect vendor and systems integrator engineering teams delivering alongside your own, setting the design and holding the quality line \nStand up evaluation and monitoring for everything you ship, so agent quality is measured rather than asserted \nContribute working patterns, SDK modules, and reference implementations back to the shared library after every build, and retire the ones that stop earning their place \nBuild handoff packages, including runbooks, dashboards, and documentation, that let business and platform partners own solutions long term \nMentor engineers across the function and set architectural guardrails others can follow without you in the room \nRequired Qualifications\n8+ 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 \nProduction grade Python and/or TypeScript; Rust is a plus \nHands on LLM application development: agent design, tool calling, prompt engineering, retrieval, and evaluation \nWorking depth in the agent interoperability stack: MCP, A2A, Watson ADK, and LangChain or comparable frameworks \nTechnical leadership across several concurrent teams or deliveries \nDaily use of AI powered coding assistants as working engineering tools \nExperience directing vendor engineering teams or systems integrators \nPreferred Qualifications\nTwo or more enterprise AI platforms (AWS, Azure or Vertex, watsonx, Writer, Copilot Studio, or comparable) \nProduction retrieval systems: vector stores, embedding models, chunking and context strategy, offline and online evaluation \nMulti agent orchestration frameworks or vendor native agent SDKs \nReusable engineering assets, such as SDKs, libraries, or reference architectures, adopted by teams outside your own \nEnterprise governance and compliance workflows for AI, including security, privacy, and model risk \nREST API integration design in a large enterprise, and architecture documentation that stands up to a review board \nHospitality, travel, or large scale consumer services \nAt Marriott International, we are dedicated to being an equal opportunity employer, welcoming all and providing access to opportunity. We actively foster an environment where the unique backgrounds of our associates are valued and celebrated. Our greatest strength lies in the rich blend of culture, talent, and experiences of our associates. We are committed to non-discrimination on any protected basis, including disability, veteran status, or other basis protected by applicable law.","description_format":"text","description_chars":4167,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Hotels & Resorts"],"lifecycle":[{"event":"open","at":"2026-10-29T19:43:52Z"}],"visa":[],"liveness":{"score":81,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":0.9,"age_days":1,"expected_fill_days":3,"reasons":["conf:0","velocity","win:mid","comp:brand"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/marriott-international-director-ai-application-engineering","json_url":"https://alion.io/job/marriott-international-director-ai-application-engineering.json","meta":{"generated_at":"2026-10-31T21:00:21Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":32982,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":800},"rest":"https://alion.io/mcp/rest/get_company?id=800"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmarriott-international-director-ai-application-engineering"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fmarriott-international-director-ai-application-engineering"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fmarriott-international-director-ai-application-engineering"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/marriott-international-director-ai-application-engineering\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmarriott-international-director-ai-application-engineering"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3479296}},{"tool":"search_jobs","arguments":{"company":"marriott.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3479296},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
