This is a unique opportunity to a significant portion of the tech stack and grow into a leadership role with considerable upside in equity.\nYou’ll be working on infrastructure that combines large-scale data systems with AI-native agents. This is a highly autonomous, high-leverage role with ownership over core architecture and early team culture.\nYou’ll be writing production code across backend and frontend, defining interfaces between components, shaping devops and data infrastructure, and helping translate abstract concepts into working systems. If you’re someone who prefers fast feedback, direct impact, and long-term upside - this is for you.\nResponsibilities\nArchitect and build scalable APIs, backend services, and web application components\n\nContribute across the stack: data pipelines, agents, web UIs, deployment systems\n\nDesign and implement internal tooling, testing frameworks, and CI/CD pipelines\n\nCollaborate closely with product and design to prototype and ship features quickly\n\nHelp define engineering processes, contribute to documentation, and grow the early team\n\nOur Stack\nAn ability to learn and grasp new technologies quickly trumps knowing the entire tech stack - you should be comfortable learning and adapting in a fast-moving environment. The following represents the types of technologies you will be working with:\nLanguages: TypeScript (Node.js), Python (FastAPI)\nFrontend: React, Next.js, Tailwind, shadcn/ui\nBackend: Postgres, DuckDB, GraphQL (Hasura), Kafka, REST\nCloud/Infra: AWS, Docker, GitHub Actions, ArgoCD, Kubernetes (basic)\nAI/Agents: LangChain, LangGraph, OpenAI, Anthropic, LLaMA, Pinecone, Qdrant\nGovernance: Keycloak, Open Policy Agent (OPA), OpenTelemetry, Slack integrations\nVisualization: Vega, Flourish, React ReChart\nConnectors: ERP, PLM, Excel, Email, Web APIs\nWhat We’re Looking For\nExperience:\n5+ years as a full stack or backend engineer\n\nExperience owning and delivering production systems end-to-end\n\nPrior experience with modern frontend frameworks (React, Next.js)\n\nFamiliarity with building APIs, databases, cloud infrastructure, or deployment workflows at scale\n\nComfortable working in early-stage startups or autonomous roles, prior experience as a founder, founding engineer, or a 0-1 pre-seed startup is a big plus \n\nMindset:\nComfortable with ambiguity, eager to prototype and iterate quickly\n\nStrong sense of ownership - prefers to build systems rather than wait for tickets\n\nEnjoys thinking about architecture, performance, and tradeoffs at every level\n\nClear communicator and pragmatic team player\n\nValues equity and impact over prestige or hierarchy\n\nPrior startup or founding team experience\n\nBonus:\nContributions to open-source or internal tools with impact\n\nInterest in data systems, agent workflows, or LLM orchestration\n\nWhy Join\nTrue ownership - early equity and influence over product and technical direction\n\nMission-driven team solving complex data and AI problems with real-world impact\n\nStrong engineering culture focused on velocity, clarity, and long-term thinking\n\nLearning curve across AI, data infra, agents, and enterprise-scale platforms\n\nEarly access to cutting-edge AI workflows and deployment patterns\n\nIf you want to build systems that learn, act, and evolve - with the autonomy to shape the stack and the team - we’d love to hear from you.","description_format":"text","description_chars":3718,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Industrial AI","Supply Chain AI"],"lifecycle":[{"event":"open","at":"2026-09-11T13:57:11Z"},{"event":"open","at":"2026-09-25T23:10:46Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 1","filings_12m":1,"filings_prev_12m":0,"green_card_filings_12m":0,"median_offered_wage_usd":167500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":1}],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.298,"p_room":0.28,"age_days":444,"expected_fill_days":36,"reasons":["conf:1","urgency","win:tail","crowd:"],"computed_at":"2026-10-29T05:49:05Z"},"pay":null,"html_url":"https://alion.io/job/fabrion-founding-engineer","json_url":"https://alion.io/job/fabrion-founding-engineer.json","meta":{"generated_at":"2026-10-29T19:48:15Z","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":29371,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-30T00:00:00Z"}},"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":720009},"rest":"https://alion.io/mcp/rest/get_company?id=720009"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffabrion-founding-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%2Ffabrion-founding-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%2Ffabrion-founding-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/fabrion-founding-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffabrion-founding-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":745205}},{"tool":"search_jobs","arguments":{"company":"fabrion.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":745205},"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.
