Job description

Our mission

Software is a civilizational bottleneck.

Every aspect of our society, from finance and agriculture to manufacturing and healthcare, fundamentally relies on software. Yet, as software teams scale, they crawl to a halt.

At cubic, we’re building an AI-native replacement to Github that helps teams collaborate and ship better code, faster.

Teams like Cal.com, n8n, 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 role

We’re looking for our first Design Engineer. Someone who can design how engineers and teams interact with code in the AI era, and write code to bring those designs to life.

Who you are

• You seebeauty as the result of ruthless functional simplicity. You think holistically about user experience, visual design, andergonomics.
• Have great taste.You have a strong, opinionated sense of what good looks like. You obsess over the details that make products feel sharp, intentional, and cohesive. You know when to break the rules—and when not to.
• Aren’t afraid to write code.You don’t stop at Figma. You’re comfortable bringing your designs to live using React and TailwindCSS. AI gives designers unprecedented power to code, and you're ready to wield it.

Why design 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 founderswho 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. Cal.com, n8n, the Linux Foundation, and others rely on cubic to ship code.
