If we had a motto it would be “no vibes allowed” - we believe that AI agent-enabled coding is a deeply technical engineering craft, and we’re building CodeLayer to unlock it at scale. A Stanford study from June 2025 said AI can’t solve hard problems or work well in complex or legacy codebases, and we’re proving them wrong with advanced techniques inspired by Context Engineering (a term originally coined by our CEO Dex in April 2025). Learn more about our mission and learnings at https://hlyr.dev/ace-fca\nOur product is an Agentic IDE built on claude code that helps CTOs and VPEs drive the transition to 99% AI-written code in their engineering orgs. Our MRR grew 100% last month, and we’re bringing on a founding engineer who loves to ship like crazy and get in the weeds with customers to solve big problems in AI Developer Productivity.\nYou…\nWork across the entire stack - frontend apps, backend services, native executables, infrastructure, CI\nHave deep experience building in the Typescript ecosystem. We use it across the entire stack - frontend, backend, native executables, infrastructure-as-code.\nShip like an engineer, think like a product owner. You have deep empathy for users and are dedicated to creating a world-class user experience.\nStrong in CS fundamentals - operating systems, networking, data structures.\nYou’re a 99th-percentile Claude Code or Codex user\nYou know Postgres/MySQL like the back of your hand\nLove working with customers to solve their problems. Expect to be forward-deployed to help onboard new customers.\nEnjoy hotkeymaxxing - vim, superhuman, RTS games, etc.\nAre familiar with auth’n/z - OAuth 2.0, etc.\nAre located in SF or willing to relocate (we’ll cover reasonable relocation costs!)\nWe:\nWork 70 hours/week in-person in SF (Marina/Russian Hill)\nAre growing rapidly and onboarding design partners. We grew 100% last month and expect to do it again.\nHave raised > 3M from YC, Pioneer Fund, and angels including Guillermo Rauch, Paul Klein, and .\nBelieve you should make it run, make it right, make it fast. Our #1 goal is deliver value for developers. Refactor after patterns emerge\nVideo call intro\nTake-home - open-ended\nFollow-up on take-home; review over video call\nOn-site (full-day-ish) - whiteboarding, hands-on coding\nWork Trial","description_format":"text","description_chars":2359,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Code Intelligence","AI Development Tools","Developer Tools"],"lifecycle":[{"event":"open","at":"2026-08-13T06:05:19Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.368,"p_room":0.28,"age_days":63,"expected_fill_days":31,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/humanlayer-founding-product-engineer","json_url":"https://alion.io/job/humanlayer-founding-product-engineer.json","meta":{"generated_at":"2026-10-17T03:46:53Z","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":4972,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":15173},"rest":"https://alion.io/mcp/rest/get_company?id=15173"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhumanlayer-founding-product-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%2Fhumanlayer-founding-product-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%2Fhumanlayer-founding-product-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/humanlayer-founding-product-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhumanlayer-founding-product-engineer"}]}
