CopilotKit is the #1 open-source platform for building AI Copilots—intelligent agents designed to work alongside people inside real products. In under 18 months, we’ve built a fast-growing and active community (18k+ GitHub stars, tens of thousands of weekly installs, millions of copilot interactions, double-digit MoM growth), are already monetizing at the enterprise level, and are used by companies ranging from startups to Fortune 100s—powering both SaaS Copilots and “Cursor for anything” coworker Copilots.
We’re emerging as the default for a critical part of the AI stack: the agent/user interaction layer. CopilotKit brings agents out of demos and terminals and into production—through deep integrations with the leading AI infrastructure companies and hyperscalers.
Backed by $6.5M (lead by SignalFire), our small, fast-moving team is building the infrastructure that will define how user-interactive AI is actually used in the real world. This is a unique opportunity to join as a founding engineer on one of the most complex and high-leverage surfaces in AI—with significant scope for technical, product, and leadership growth.
As a Product Designer specializing in developer infrastructure at CopilotKit, you'll craft experiences that make complex AI capabilities accessible and delightful for developers. You'll balance technical depth with user empathy to create intuitive interfaces, documentation, and design systems that developers love.
You'll collaborate with engineers and product leaders to shape our open-source tools and enterprise platform, ensuring our developer experience meets the high bar set by companies like Stripe and Vercel. Your work will directly influence how thousands of developers integrate AI copilots into their applications, ultimately affecting millions of end users.
