The role

## Our missionEvery aspect of the modern world—from finance and agriculture to manufacturing and healthcare—runs on software. Yet as software teams grow, they paradoxically slow down.At cubic, we’re building an AI-native replacement to Github that helps teams collaborate and ship better code, faster.Teams like n8n, Granola, Browser Use and the Linux Foundation use cubic every single day.We’re founded by repeat-founders, and backed by Y-Combinator.Our 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)### The roleWe’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.### Who you are* **You obsess over users and product outcomes:** You care just as much about the end-user experience as the tech stack.* **Comfortable with a modern tech stack:** cubic is built on Next.js, React, Prisma, Inngest, Supabase, Modal, and Vercel AI SDK.* **Comfortable owning features end-to-end**—from ideation and development through to deployment, launch, and iteration.* **Adaptable:** 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* **Have a track record of being a self-starter:** Side projects and/or open source contributions.* **You’ve been doing software development for 5+ years.**### Why build cubic?* **Define 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.* **Work directly alongside founders** who built and shipped major products at Instagram and Tessian.* **Impact 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.
