You'll own projects end-to-end in a fast-\nmoving, early-stage environment and help shape the core infrastructure that AI agents\nuse to communicate and operate in the real world.\nWhat You'll Do\n\nBuild and design APIs and backend infrastructure that AI agents use to communicate, authenticate, and operate\nOwn 0→1 projects end-to-end - from scoping customer requirements through system design to production rollout (e.g., IMAP integration, usage-based pricing systems)\nWork across the full stack (~80% backend, ~20% frontend/other), touching distributed systems, databases, and developer tooling\nProactively pitch ideas - you're expected to bring product and growth thinking,\nnot just execute tickets\nBe a frontline point of contact for customer feedback and support enterprise deployments\nWrite clear, maintainable code and documentation while processing hundreds of thousands of emails per day\nWhat We're Looking For\n\nStrong proficiency in TypeScript or modern equivalent frameworks\nExperience at a FAANG or well-known VC-backed startup (Series A+)\nDeep backend fundamentals: REST API design, system design, server-side architecture\nTrack record of shipping and owning features from 0→1 in production with real users\nCS or technical degree from a top engineering school (especially for new grads)\nHigh agency - you bring ideas and drive execution without needing scope handed to you\nStrong communicator of tradeoffs, blockers, and technical decisions\nMust be based in or willing to relocate to San Francisco (on-site 5 days/week)\nBonus Points\n\nExperience with email, messaging, or protocol-heavy systems (SMTP, IMAP, OAuth)\nExposure to cloud infrastructure, distributed systems, or developer tooling - especially in AI/LLM or agent workflows\nPrior founding, fellowship, or 0-to-1 building experience\nEvidence of doing hard things outside of engineering - competitive athletics, self-directed projects, anything showing grit and agency","description_format":"text","description_chars":2197,"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":[]},"benefits":[],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":[],"lifecycle":[{"event":"open","at":"2026-11-08T18:10:45Z"}],"visa":[{"country":"GB","licensed_sponsor":false,"adverts_offering_sponsorship_24m":3,"sanctioned_now":false,"evidence":"Offered visa sponsorship in 3 of its adverts here in 24 months","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":null,"cap_exempt":false,"checked_at":"2026-11-12T09:37:45+00:00","sources":["Alion: sponsorship offered in the employer's own job adverts (24 months)"],"filings_for_role_12m":0}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":3,"expected_fill_days":23,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-11-12T10:38:37Z"},"pay":null,"html_url":"https://alion.io/job/remotestar-founding-engineer-backend","json_url":"https://alion.io/job/remotestar-founding-engineer-backend.json","meta":{"generated_at":"2026-11-12T19:47:56Z","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":41775,"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":4526839},"rest":"https://alion.io/mcp/rest/get_company?id=4526839"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fremotestar-founding-engineer-backend"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fremotestar-founding-engineer-backend"},{"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%2Fremotestar-founding-engineer-backend"},{"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/remotestar-founding-engineer-backend\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fremotestar-founding-engineer-backend"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3944218}},{"tool":"search_jobs","arguments":{"company":"remotestar.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3944218},"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.
