We don’t want someone who closes tickets because they were assigned. We want someone who figures out what’s worth building and checks that it works for the people using it.\nFull Stack Engineer At Expensify\nWe’re looking for a resourceful, self-directed engineer who is excited to work across product and engineering. You’ll work closely with other engineers, designers, customer-facing teams, and external contributors to turn rough ideas into reliable, shipped features.\nWhy Join Us?\nOwn high-impact projects. We’re a small team. You’ll take projects from the first idea to a shipped feature, and you’ll be trusted to make the decisions along the way without handing them off or waiting for sign-off.\n\nWork at the intersection of product, code, and AI. AI is part of the product as a whole, not a separate effort. You’ll build features with it every day, and you’ll help decide what we build as well as how we build it.\n\nWork with people who care about the craft. You’ll be surrounded by smart, thoughtful colleagues who care about the quality of what we ship and the results it delivers, and who will hold your work to the same standard.\n\nAbout You\nYou manage yourself. We’re a flat organization, so nobody sets your day. You decide what matters, figure out for yourself whether it’s working, and keep moving without waiting to be told\n\nYou write clearly, in code and in prose. We’re remote-first, so most of our thinking happens in docs, threads, and pull requests.\n\nYou think like a product owner. You ask who a feature is for and why it matters first and enjoy getting into the predesign conversations.\n\nYou work fluently with AI. We use it constantly, and you know how to direct it, check its work, and tell when it’s leading you astray\n\nYou review others’ work with care. You can give direct, thoughtful feedback to open-source contributors and help them work better without slowing them down\n\nYou have a strong grasp of design patterns and system design, and you can apply them in a production codebase\n\nYou can work fluidly across departments, such as design, customer-facing teams, and engineering, and you’re great at communicating needs and tradeoffs\n\nYou’re ambitious about your own growth and want to use this role to get somewhere specific, not staying comfortable anywhere for long.\n\nYou have a self-starter mindset: proactively spotting gaps, diagnosing issues, and rolling up your sleeves to build or fix the most valuable thing without being asked\n\nYou have a work ethic unequaled by your peers, are the hardest worker in the room, and are a force multiplier, inspiring others to follow your example.\n\nDaily Focus & Responsibilities\nPlan, build, and maintain cross-stack features like accounting integrations, advanced receipt scanning, calendar integrations, and credit card transaction imports\n\nSquash bugs and improve the reliability of our app, so the things we ship keep working\n\nMaintain and improve high-quality code to give customers industry-leading experiences\n\nReview pull requests from internal engineers and external contributors, guiding both quality and direction\n\nUse AI tools across your workflow to increase efficiency, with good judgment about when to trust the output and when to dig in\n\nMake product calls on what to build, what to cut, and what to rethink, with clear reasoning for each\n\nSpot repetitive work and automate it, so no one does by hand what a script can do\n\nShare what you know: we’ll share our editor tricks, dotfiles, and productive workflows, and we want yours too\n\nLift up the team around you to do more with less, work smarter, and pitch in to keep the lights on.\n\nWhat We’re Looking For\nStrong command of design patterns and system design, applied in production-level code\n\nClear communication, written and spoken, including native-level English\n\nA natural problem solver who automates solutions instead of repeating work\n\nAn understanding of the role and impact programming has on the organization as a whole\n\nA drive to grow your skills in programming and leadership within the organization\n\nExperience with JavaScript, React, React Native, PHP, C++, Java, iOS, or Android\n\n(Bonus) Experience in maintaining a codebase that takes outside contributions, such as an open source project\n\nCompensation & Benefits\nFull-time salaried position\n\n401k with employer match\n\n100% medical/dental/mental health support/vision contributions\n\n$20k annual family planning benefit through Carrot\n\nUp to 3 months of fully paid parental leave, with up to 6 months for birthing parents\n\n$5k relocation reimbursement if you move to one of our US offices (NYC, SF or PDX)\n\nCommuter benefits\n\nFlexible vacation policy\n\nWe’re committed to providing a fair and inclusive hiring experience. If you need a reasonable accommodation at any stage of the process, just let us know-we’re happy to help","description_format":"text","description_chars":4997,"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":[{"language":"English","level":"All levels","optional":false}]},"benefits":["401k plan","Flexible vacation policy","Parental leave"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Accounting & Tax Software","Procurement & Spend Management"],"lifecycle":[{"event":"open","at":"2026-10-30T02:52:45Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"green card filings: 1","filings_12m":0,"filings_prev_12m":0,"green_card_filings_12m":1,"median_offered_wage_usd":217500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":0}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":2,"expected_fill_days":27,"reasons":["conf:0","win:early"],"computed_at":"2026-11-01T06:10:25Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/expensify-full-stack-engineer","json_url":"https://alion.io/job/expensify-full-stack-engineer.json","meta":{"generated_at":"2026-11-01T17:08:47Z","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":26232,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":58562},"rest":"https://alion.io/mcp/rest/get_company?id=58562"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fexpensify-full-stack-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%2Fexpensify-full-stack-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%2Fexpensify-full-stack-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/expensify-full-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fexpensify-full-stack-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3499117}},{"tool":"search_jobs","arguments":{"company":"expensify.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3499117},"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.
