About the role

Our mission:

Every 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).
