We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth.\nAbout the Role\nWe’re looking for a Software Engineer to join our AI Tooling team and help shape how developers and agents build with Supabase. You'll build and own our AI tooling, including agents, the MCP server, agent skills and the dashboard assistant, and as the space moves you'll build the tooling for new technologies too. You'll build it all eval-first: every tool ships with evals and metrics, so we know, with evidence, that it makes agents better rather than worse.\nYou'll work closely with the Docs, CLI, Frontend and SDK teams, and with the AI Tooling Infrastructure engineers who run these services in production. Other teams contribute to AI Tooling to improve Supabase's agentic capabilities, and you'll help them do that while keeping the quality bar high.\nThis role is ideal for someone who thrives in async, fast-paced environments and is excited about building developer tools that scale to millions.\nWhat You’ll Be Responsible For\nBuild and improve the AI tooling we run today, including the MCP server, agent skills, agents and the Assistant.\n\nMake new Supabase products usable by agents from day one: tools, skills and evals for new product surfaces. Also build tooling for new AI technologies as they emerge: prototype quickly, evaluate honestly, and decide with the team what is worth taking to production.\n\nDrive an eval-first approach: build and improve evals, instrumentation and feedback loops, measure tools against a no-tool baseline, and help define the quality KPIs and gates that stop regressions shipping.\n\nUnderstand how customers and agents actually use what we ship, and turn that into improvements to our tooling, interfaces and documentation.\n\nDesign how documentation and product knowledge are exposed to agents, and measure whether it works.\n\nBuild patterns and tools that help customers add AI to their own apps, such as MCP on Edge Functions, vector embeddings and agents running on Edge Functions.\n\nEnable teams to improve Supabase's agentic capabilities through contributions to AI Tooling: clear contribution paths, templates, documentation and review practice.\n\nCentralise shared AI logic so teams reuse it rather than duplicate it.\n\nShip tools that are battle-tested, with strong tests, benchmarking and stress testing where it counts.\n\nWork with the AI Tooling Infrastructure engineers on reliability, auth and hosting.\n\nWork across Docs, CLI, Frontend, SDK and other teams to deliver one coherent developer experience, and stay close to the fast-moving AI ecosystem.\n\nYou Might Be a Good Fit If You\nMust have:\nHave 5+ years of experience in professional software engineering experience.\n\nWrite strong TypeScript and know the JavaScript ecosystem well: npm, ES modules, bundlers, compatibility.\n\nAre deeply familiar with the AI ecosystem: current tools, agent patterns and practical trade-offs. You can tell a durable pattern from hype.\n\nHave built developer tools, product interfaces or platform primitives used by other engineers.\n\nHave designed or used evaluation frameworks to measure AI quality, reliability and task success, and understand baselines, variance and cost.\n\nHave strong judgement about where AI improves workflows and how to avoid fragile or gimmicky experiences.\n\nWrite tests and validate reliability in real-world conditions.\n\nKnow Postgres and relational database practice.\n\nCommunicate clearly in writing, work across product, engineering and docs, and thrive in async, globally distributed teams.\n\nAre comfortable navigating ambiguity and moving quickly.\n\nNice to have:\nExperience with vector databases and embeddings, ideally pgvector.\n\nExamples of customer-facing AI features or agents you've shipped.\n\nExamples of documentation or structured knowledge designed for developers or agents.\n\nExperience with Braintrust or a similar eval and tracing platform, or setting up CI quality gates.\n\nOpen-source contributions or developer tooling you've maintained.\n\nExperience across several product surfaces or teams.\n\nWhat We Offer\nFully Remote\nWe hire globally. We believe you can do your best work from anywhere. There are no Supabase offices, but we provide a WeWork membership or co-working allowance you can use anywhere in the world.\n\nESOP\nEvery team member receives ESOP (equity ownership) in the company. We want everyone to share in the upside of what we’re building together.\n\nTech Allowance\nUse this budget to set up your ideal work environment-laptop, monitor, headphones, or whatever helps you do your best work.\n\nHealth Benefits\nSupabase covers 100% of health insurance for employees and 80% for dependents, wherever you are. Your wellbeing and your family’s health are important to us.\n\nAnnual Off-Sites\nOnce a year, the entire company gathers in a new city for a week of connection, collaboration, and fun. It’s a highlight of our year.\n\nFlexible Work\nWe operate asynchronously and trust you to manage your own time. You know what needs to be done and when.\n\nProfessional Development\nEvery team member receives an annual education allowance to spend on learning-courses, books, conferences, or anything that supports your growth.\n\nAbout the Team\nSupabase was born-remote and open-source-first. We believe our globally distributed team is our secret weapon in building tools developers love.\n~400 team members\n\n60+ countries\n\n20+ languages spoken\n\nOver $1B raised (including our $500M Series F)\n\n540,000+ community members\n\nWe move fast, build in public, and use what we ship. If it’s in your project, we probably use it in ours too. We believe deeply in the open-source ecosystem and strive to support-not replace-existing tools and communities.","description_format":"text","description_chars":5906,"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","Flexible schedule","Health insurance","Professional development"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Cloud Platforms (IaaS & PaaS)","Databases & DBMS","Developer Tools"],"lifecycle":[{"event":"open","at":"2026-11-10T18:31:06Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":1,"expected_fill_days":67,"reasons":["conf:4","stale_co","velocity","win:early","comp:remote,attention"],"computed_at":"2026-11-12T10:38:37Z"},"pay":null,"html_url":"https://alion.io/job/supabase-software-engineer-ai-tooling","json_url":"https://alion.io/job/supabase-software-engineer-ai-tooling.json","meta":{"generated_at":"2026-11-12T22:42:41Z","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":48038,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-13T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":17114},"rest":"https://alion.io/mcp/rest/get_company?id=17114"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsupabase-software-engineer-ai-tooling"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fsupabase-software-engineer-ai-tooling"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fsupabase-software-engineer-ai-tooling"},{"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/supabase-software-engineer-ai-tooling\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsupabase-software-engineer-ai-tooling"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4030588}},{"tool":"search_jobs","arguments":{"company":"supabase.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4030588},"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.
