We build technology that helps Silicon Valley's fastest-growing companies, incubators, and investors navigate immigration. More than half of Silicon Valley startups have at least one immigrant founder - and only by bridging the gap between talent and opportunity can we power innovation. Read more here, here, and here.\nThe Role\nAs our founding Full Stack Engineer, you'll drive Plymouth's technical direction while remaining deeply hands-on. You'll architect the product, ship features daily, and build the engineering function as the company grows. You'll help decide what we build, how we build it, and eventually who builds it.\nOur stack today includes Ruby on Rails, Typescript, React, Node, and Postgres, on infrastructure across Render and AWS.\nYou’ll take ownership of an established production application and services, improving and extending the existing codebase while delivering new features and exploring new product offerings. This includes refining existing functionality, refactoring parts of the system, designing and implementing AI-powered capabilities, integrating third-party services, and continuously improving our engineering practices.\nWhat You'll Own\nOwn Plymouth's technical direction while designing, building, testing, and shipping software across the full stack.\n\nPartner with the founder on product direction and turn ambiguous problems into shipped features.\n\nBuild the engineering organization over time - whether that's managing external partners, hiring engineers, or both.\n\nOwn performance, reliability, and scalability across the product.\n\nWho You Are\n4+ years building production software, with experience leading significant technical projects or teams.\n\nStrong across React, Node.js, Postgres, and modern cloud infrastructure.\n\nFluent with AI-assisted development (Cursor, Copilot, Claude Code, or similar) and thoughtful about where these tools create leverage.\n\nComfortable setting technical direction while staying close to the code.\n\nHumble, intrinsically motivated, and willing to own whatever the business needs.\n\nStrong communicator who enjoys collaborating across functions.\n\nBonus:\nExperience building AI/LLM-powered products or taking products from zero to one.\n\nExperience with Python.\n\nExperience leading engineers or coordinating external/contract teams.\n\nBackground in security and compliance, or working with operations teams to drive efficiency.\n\nExperience in the immigration domain.\n\nWhy Join Now\nPlymouth is still small enough that one person can fundamentally shape the trajectory of the company, but established enough to work with many of Silicon Valley's fastest-growing startups from day one. You'll have real ownership, direct access to the founder, and the opportunity to shape both the company and your role as we grow.","description_format":"text","description_chars":2919,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Legal Services","Legal Software"],"lifecycle":[{"event":"open","at":"2026-09-30T02:37:04Z"}],"visa":[],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.202,"p_room":0.28,"age_days":101,"expected_fill_days":21,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-23T05:54:15Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/plymouth-street-2022-founding-full-stack-engineer","json_url":"https://alion.io/job/plymouth-street-2022-founding-full-stack-engineer.json","meta":{"generated_at":"2026-10-23T08:11:40Z","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":13072,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":1954151},"rest":"https://alion.io/mcp/rest/get_company?id=1954151"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fplymouth-street-2022-founding-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%2Fplymouth-street-2022-founding-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%2Fplymouth-street-2022-founding-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/plymouth-street-2022-founding-full-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fplymouth-street-2022-founding-full-stack-engineer"}]}
