Yet as software teams grow, they paradoxically slow down.\nAt cubic, we’re building an AI-native replacement to Github that helps teams collaborate and ship better code, faster.\nTeams like n8n, Granola, Browser Use and the Linux Foundation use cubic every single day.\nWe’re founded by repeat-founders, and backed by Y-Combinator.\nOur investors are some of the world’s greatest builders - Vercel Ventures, PeakXV (ex-Sequoia India), Jared Palmer (Creator of v0 and Vercel AI SDK), Theo Browne (Dev influencer), and Zeno Rocha (Founder of Resend)\nThe role\nWe’re looking for our first Founding Product Engineer. A builder with hardcore software engineering skills, plus the autonomy, taste, and pragmatism to be their own PM.\nWho you are\nYou obsess over users and product outcomes: You care just as much about the end-user experience as the tech stack.\n\nComfortable with a modern tech stack: cubic is built on Next.js, React, Prisma, Inngest, Supabase, Modal, and Vercel AI SDK.\n\nComfortable owning features end-to-end -from ideation and development through to deployment, launch, and iteration.\n\nAdaptable: You’re excited to wear multiple hats and jump around different parts of the codebase. You’re not afraid to jump into new technologies and prototype quickly\n\nHave a track record of being a self-starter: Side projects and/or open source contributions.\n\nYou’ve been doing software development for 5+ years.\nWhy build cubic?\nDefine an entirely new product category. We’re living in a short time window where a small group of builders can shape how we build software in the coming decades.\n\nWork directly alongside founders who built and shipped major products at Instagram and Tessian.\n\nImpact billions of users: software teams who use cubic are building products that reach billions of users. n8n, Granola, the Linux Foundation, and others rely on cubic to ship code.","description_format":"text","description_chars":1992,"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":false,"industries":["Code Intelligence"],"lifecycle":[{"event":"open","at":"2026-08-18T12:40:02Z"}],"visa":[],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":1,"p_active":0.39,"p_room":0.28,"age_days":66,"expected_fill_days":30,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-24T06:02:35Z"},"pay":{"stated_usd_annual":160511,"is_top_pay":false},"html_url":"https://alion.io/job/cubic-founding-product-engineer-cubic-yc-x25","json_url":"https://alion.io/job/cubic-founding-product-engineer-cubic-yc-x25.json","meta":{"generated_at":"2026-10-25T03:06:24Z","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":4639,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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":20802},"rest":"https://alion.io/mcp/rest/get_company?id=20802"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcubic-founding-product-engineer-cubic-yc-x25"},{"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%2Fcubic-founding-product-engineer-cubic-yc-x25"},{"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%2Fcubic-founding-product-engineer-cubic-yc-x25"},{"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/cubic-founding-product-engineer-cubic-yc-x25\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcubic-founding-product-engineer-cubic-yc-x25"}]}
