You will work directly with teams deploying agents in production and translate what you learn into improvements in the Mastra framework itself.\nWhat You’ll Own\nWithCustomers\nCollaborate directly with customer teams building real agent systems\n\nDesign and implement agents alongside their engineers\n\nImprove reliability, eval strategies, monitoring, and scaling approaches\n\nHelp teams move from prototype to durable systems\n\nTrain and upskill customers to become Mastra experts\n\nShare patterns and best practices across accounts\n\nWhen agents break or systems stall, you help make them stronger and more repeatable.\nIn the Core Framework\nTurn recurring customer challenges into OSS improvements\n\nFix reliability and performance issues\n\nShip new primitives and refine existing ones\n\nRaise the quality bar across the codebase\n\nContribute to roadmap direction through firsthand production insight\n\nYou’ll convert real-world friction into durable primitives.\nWho This Is For\nThis role is for engineers who:\nHave built and operated AI systems in production\n\nCan move from implementation details to system-level thinking\n\nSee patterns where others see one-off issues\n\nCare deeply about developer ergonomics\n\nPrefer ownership over narrow scope\n\nYou should be comfortable moving between hands-on customer collaboration and foundational platform design.\nWhy This Role Is Different\nMost companies separate customer-facing engineering from core product engineering. We don’t. The best platform improvements come directly from real-world usage. This role exists to compress that loop. If you want to work on real systems and influence the primitives that define how agent infrastructure is built, this is that role.\nHiring Process\n1) Intro call with our recruiter\n2) Hiring Manager Interview. Call with Shane Thomas, our co-founder and CPO, who leads customer engineering.\n3) Peer Interview. Conversation with one of our customer engineers you'd be working alongside.\n4) Take-home project `+ project review with our customer engineering team.\nAbout Mastra\nMastra is the open-source TypeScript framework for building AI agents. Built by the team behind Gatsby, backed by Y Combinator and Spark Capital, with $35M raised total. We went from 0 to 28k+ stars and 2M+ weekly npm downloads in less than 2 years.\nSmall team, shipping fast, fully remote. Most of us work across North American and European time zones.","description_format":"text","description_chars":2571,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","AI Development Tools","AI Evaluation & Observability"],"lifecycle":[{"event":"open","at":"2026-09-05T09:43:01Z"}],"visa":[],"liveness":{"score":16,"band":"cold","label":"Long shot","p_open":1,"p_active":0.433,"p_room":0.36,"age_days":65,"expected_fill_days":34,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-11-07T05:47:08Z"},"pay":null,"html_url":"https://alion.io/job/mastra-customer-engineer","json_url":"https://alion.io/job/mastra-customer-engineer.json","meta":{"generated_at":"2026-11-07T09:59:16Z","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":8456,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-08T00:00:00Z"}},"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":7775},"rest":"https://alion.io/mcp/rest/get_company?id=7775"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmastra-customer-engineer"},{"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%2Fmastra-customer-engineer"},{"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%2Fmastra-customer-engineer"},{"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/mastra-customer-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmastra-customer-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":230676}},{"tool":"search_jobs","arguments":{"company":"mastra.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":230676},"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.
