We handle autoscaling, observability, and the messy details of web interaction, so developers can focus on what their agents do instead of how they do it.\nTeams at Cash App, Rye, and 3000+ others use Kernel for deep research, QA automation, and real-time web analysis. We've raised $22M from Accel, YC, and Vercel.\nIf you're interested in building critical infrastructure for agents on the web, we'd love to chat.\nAbout the role\nProduct Engineers at Kernel are full-stack engineers who think about the product as much as the code. You know how to translate your strong product instincts into code, from pixel-level UI decisions to backend API design. You don't wait for a spec, you help write it.\nYou'll work closely with our co-founders to set product direction, ship full-stack features end-to-end, and make Kernel feel as polished as it is powerful.\nWhat you’ll do\nOwn customer outcomes and product metrics\n\nExecute the full-stack implementation of user-facing product surfaces, including our core product and new product lines\n\nShape the product roadmap by synthesizing customer feedback, usage patterns, and your own instincts about what developers need\n\nDrive DX improvements across our SDK, docs, CLI, and API. The kind of details that make developers say \"this just works\"\n\nShip fast and iterate, from prototype to production with minimal hand-holding\n\nHelp define what it means to build a great developer product at Kernel\n\nWhat we're looking for\nYou're driven by customer outcomes: you're empathetic to customers, naturally inclined to help them succeed in their goals through KERNEL, and obsessed with metrics that matter to them\n\nYou ship end-to-end: you're comfortable owning a feature from frontend to backend and getting it across the finish line\n\nYou have product taste: you've thought hard about what makes developer tools feel magical vs. frustrating, and that thinking shows up in your work\n\nStartup experience: you've built fast, worn multiple hats, and figured things out without a playbook\n\nYou build for developers deploying agents into the real world\n\nYou have strong opinions about devEx and API design, and you know how to back them up with shipped work\n\nWhat you can expect as a Kernel\nIndustry-competitive salary\n\nAbove market equity\n\nPremium medical + dental coverage + dependent coverage\n\nSmall, trusting team of senior + staff engineers\n\nDefault async with minimal bureaucracy, only two meetings a week\n\n$1k / mo budget for LLM usage fees #vibecheck\n\nDaily lunches on us\n\nUnlimited PTO\n\n401k + company match\n\nRelocation assistance\n\nHiring process\nWe have a simple process focused on real world collaboration and jointly getting to know each other:\n30-minute intro call with one of Kernel’s co-founders\n\n45-minute technical interview (virtual)\n\nHalf-day on-site (virtual or in-person) working with our team on relevant challenges.\n\nOffer!","description_format":"text","description_chars":2953,"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":["401k plan","Equity","Relocation assistance","Unlimited PTO"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Developer Tools"],"lifecycle":[{"event":"open","at":"2026-02-27T16:24:59Z"}],"visa":[],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.199,"p_room":0.28,"age_days":231,"expected_fill_days":33,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/kernel-product-engineer","json_url":"https://alion.io/job/kernel-product-engineer.json","meta":{"generated_at":"2026-10-18T12:44:19Z","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":18829,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":50861},"rest":"https://alion.io/mcp/rest/get_company?id=50861"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fkernel-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%2Fkernel-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%2Fkernel-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/kernel-product-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fkernel-product-engineer"}]}
