Commons is one of the top 50 buyers of high-integrity carbon credits in the world, offering individuals access to the highest-quality projects typically reserved for top buyers.\nCommons has scaled meaningfully with a scrappy, tenacious, passionate team of 10-15 people. We aren’t afraid to move fast and try new things to meet our customers where they are. We’re looking for one unique engineer to join our ranks.\nThe role\nEveryone on our small team builds across the whole stack, and you will too. You’ll also play the specific role of leading the backend and platform side of Commons (data models, integrations, infrastructure, and security), complementing your teammates’ frontend and product expertise.\nThis is a mid to senior IC role, with room to grow in influence and scope. You’ll solve new problems every day across multiple surfaces, switching from polishing frontend features to architecting databases; alternating between mobile and web development; and going between building frontend tests for your own code to helping a teammate automate their workflow.\nYou’ll be responsible for:\nBuilding features end to end, from database to UI, and reviewing PRs\n\nDesigning and evolving our core data models, and review migrations before they go out\n\nOwning our third-party integrations and making build vs. buy calls\n\nRunning CI/CD (GitHub Actions and CircleCI), monitoring (New Relic, Sentry), and infrastructure on Render, Postgres, and Redis\n\nLead in any outages and escalations, especially anything infrastructure-related\n\nKeeping dependencies up to date, and simplifying the stack where you can\n\nWorking with our data team to improve privacy and security practices\n\nHelping build out AI coding tools and workflows team-wide to increase speed and efficacy\n\nThe team\nYou'll join a distributed engineering team of three other engineers, one in the US and two in Manila, all working across the stack. You’d lead backend architecture and own backend and platform decisions.\nYou’ll partner closely with product, design, marketing, and data teammates to make decisions and coordinate on new features and capabilities. Our team is highly collaborative, in touch daily over slack and video. We’re looking for a team member who likes collaborating, explains their thinking in code reviews and design discussions, and wants to build their own skills and help others to do the same.\nWhat we're looking for\n5+ years building production software across the stack, with most of your depth on the backend. We'll consider fewer years with the right experience.\n\nYou think in capabilities, not features. You look to build foundations to iterate on, rather than fully-polished final products.\n\nYou're used to building and shipping features yourself from end to end.\n\nYou’ve built backend systems from the ground up and owned production at a startup. You've set up CI, added monitoring, and been the one who got paged. You’re comfortable being the first port of call in an outage or emergency.\n\nYou know Postgres well, have designed schemas from scratch, and have run migrations on systems people were actively using.\n\nYou've built and maintained third-party integrations and made build vs. buy decisions you can defend.\n\nYou take data security and privacy seriously.\n\nYou are deeply embedded in AI and agentic coding tools. You use them to build, refine, and check your work. You’re passionate about helping others improve their workflows.\n\nYou can clearly explain technical tradeoffs to people without a technical background.\n\nYou love tackling new and different problems.\n\nYou aren’t looking to be a manager - or to be managed. You enjoy teams where everyone is building, owning, and co-creating.\n\nThink you might have what it takes, but not sure you meet every requirement? Research shows that women and marginalized folks tend to only apply when they check every box. If you're passionate about what we're building, please apply. You might be just who we’re looking for.","description_format":"text","description_chars":4412,"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":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"},{"name":"Canada","iso":"CA","kind":"country"},{"name":"Mexico","iso":"MX","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Energy & Utilities","Financial Services","Personal Finance Apps & Education"],"lifecycle":[{"event":"open","at":"2026-10-22T21:18:35Z"}],"visa":[],"liveness":{"score":68,"band":"ok","label":"Likely open","p_open":1,"p_active":0.86,"p_room":0.788,"age_days":6,"expected_fill_days":7,"reasons":["conf:3","win:late"],"computed_at":"2026-10-29T05:49:05Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/commons-full-stack-engineer-backend-focus","json_url":"https://alion.io/job/commons-full-stack-engineer-backend-focus.json","meta":{"generated_at":"2026-10-29T06:45:41Z","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":10291,"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":1903055},"rest":"https://alion.io/mcp/rest/get_company?id=1903055"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcommons-full-stack-engineer-backend-focus"},{"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%2Fcommons-full-stack-engineer-backend-focus"},{"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%2Fcommons-full-stack-engineer-backend-focus"},{"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/commons-full-stack-engineer-backend-focus\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcommons-full-stack-engineer-backend-focus"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3112335}},{"tool":"search_jobs","arguments":{"company":"thecommons.earth","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3112335},"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.
