We equip communities with AI tools and hands-on professional development that empowers educators & students to build custom AI apps for their unique context. Over 60,000 educators have published apps on Playlab - and the impact is growing every day.\nAt Playlab, we believe that AI is a new design material - one that should be shaped by many to bring their ideas about learning to life. If you're passionate about building creative, equitable futures for students and teachers, we hope you’ll join us.\nThe Role\nPlaylab seeks a Staff Fullstack Engineer to join our growing Engineering team. As a Staff Fullstack Engineer you'll be exploring and pushing the boundaries of what AI-native experiences can be - inventing new interfaces for AI interaction, building the tools that let educators create without code, and implementing the systems that help schools deploy at scale.\nExamples of the work\nBuild AI-native interfaces that push boundaries - dynamic components that adapt from chat to writing editor to interactive simulations based on learning moments\n\nDesign and implement the core application builder where educators create AI apps using natural language\n\nCreate real-time collaboration features enabling multiple educators to co-create applications together\n\nBuild systems that enable educators to create sophisticated AI agents that work autonomously toward educational goals\n\nImplement voice interfaces and mobile-first experiences that work from rural schools with limited internet to high-tech classrooms\n\nBuild discovery and sharing systems that help educators find and remix each other's applications - fostering a thriving creator community\n\nCreate integrations with Google Workspace, Canvas LMS, and other educational platforms that schools already use\n\nAnd more…\n\nExpectations\nArchitect and ship subsystems across the full stack - from React/Remix frontend to Node.js backend to integrations with Python AI services\n\nMove fast to learn what works - ship small experiments quickly, then invest in productionizing what proves valuable\n\nStay on top of web technologies and best practices - evaluate new tools and patterns that improve the product\n\nWork cross-functionally with designers, ML engineers, product, and customers to build experiences that solve real user needs\n\nWrite comprehensive tests and documentation for the features you build\n\nImprove team processes and help drive strategic technical decisions\n\nMentor engineers on fullstack development, design patterns, and app architecture through pairing and reviews\n\nQualifications\n7+ years building production web applications across frontend and backend\n\nStrong experience with modern React frameworks (we use Remix) and TypeScript\n\nStrong experience building backend services with Node and Typescript\n\nStrong experience with databases, APIs, and integrations with external services\n\nAble to work effectively with designers and translate designs into working features\n\nComfortable working cross-functionally and directly with customers to understand their needs\n\nThrive in high-agency, high collaboration cultures\n\nGreat communication that makes working remote-first work\n\nBonus Points For...\nExperience designing or building AI-powered interfaces\n\nBackground in real-time collaborative features (WebSockets, CRDTs, etc.)\n\nExperience with educational technology or mission-driven organizations\n\nExperience with Remix or similar React frameworks\n\nKnowledge of accessibility and internationalization best practices\n\nExperience integrating with LMS platforms or educational systems\n\nTechnologies\nTypeScript, Remix (React), Node, PostgreSQL, Neo4J, AWS, Docker, Kubernetes, WebSockets, NewRelic","description_format":"text","description_chars":3909,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Professional development"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Mobile Games"],"lifecycle":[{"event":"open","at":"2025-11-25T02:02:04Z"},{"event":"close","at":"2026-08-13T11:22:45Z"},{"event":"reopen","at":"2026-08-29T22:18:04Z"},{"event":"open","at":"2026-09-26T06:32:15Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.238,"p_room":0.28,"age_days":325,"expected_fill_days":44,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":210000,"is_top_pay":false},"html_url":"https://alion.io/job/playlab-staff-fullstack-engineer","json_url":"https://alion.io/job/playlab-staff-fullstack-engineer.json","meta":{"generated_at":"2026-10-16T18:54:30Z","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":4274,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":7083},"rest":"https://alion.io/mcp/rest/get_company?id=7083"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fplaylab-staff-fullstack-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%2Fplaylab-staff-fullstack-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%2Fplaylab-staff-fullstack-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/playlab-staff-fullstack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fplaylab-staff-fullstack-engineer"}]}
