The testing standards, the on-call story, how we decide what ships on a Friday, all of that is currently whatever the two of us happened to do last month. You'd be setting it, and you'd be living with it longer than we will.\nThere's also no work stream attached to this job. You go where the gap is. Some weeks that's detection quality, some weeks it's the ingest pipeline choking on a customer whose instrumentation is a mess, some weeks it's the review UI that decides whether someone trusts our PR enough to merge it. We hire this role because the constraint on a team this size is almost never a specialist.\nWhat you'll do\nShip across the whole loop: ingest, detection, patch generation, verification, the product people actually look at\nOwn the trust surface. Reproduction, guardrails, and the checks that keep a bad PR from ever reaching a customer's repo\nTake a problem from a customer conversation to something shipped, without waiting for a spec\nTalk to customers directly. You'll be in their Slack, reading their traces, hearing what broke before we do\nMake calls that outlive you. Schema decisions, service boundaries, what we're willing to be slow about\nWhat we're looking for\n3+ years shipping production software, and a track record of shipping well outside whatever you'd call your specialty\nStrong TypeScript. It's the whole codebase, frontend through the core service\nReal comfort with data at volume. You've thought about cost per event, not just correctness\nStrong product sense. You can take a rough problem and return something well considered without a Figma file waiting for you\nYou've built with agents and have opinions about why they fail\nBonus: you were the customer once. You ran agents in production and got burned\nWe move fast on hiring. Target is an offer within two weeks of first contact.\nOnsite in San Francisco. We sponsor visas.\nWe keep this short on purpose. Target is an offer within two weeks of first contact.\nIntro call with a founder (30 minutes). What we're building, what you've built, whether the shape of the role actually fits what you want next.\nTake-home project and deep dive. We give you a real problem from Lemma. You work on it on your own time, then we walk through it together. The conversation matters more to us than the artifact.\nPaid work trial (2 days, onsite in-person). Real problem, real codebase, sitting with the team. You find out what working here actually feels like before you commit, which tells you more than anything we could say about it.\nMay ask for additional references.","description_format":"text","description_chars":2830,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","AI Agents"],"lifecycle":[{"event":"open","at":"2026-09-26T02:56:15Z"}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.902,"p_room":1,"age_days":4,"expected_fill_days":37,"reasons":["conf:1","velocity","win:early"],"computed_at":"2026-09-30T05:45:00Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/uselemma-ai-founding-engineer","json_url":"https://alion.io/job/uselemma-ai-founding-engineer.json","meta":{"generated_at":"2026-10-01T00:07:03Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":103,"day_limit":5000,"remaining_today":4897,"minute_limit":60,"resets_at":"2026-10-02T00:00:00Z"}}}
