Applied AI Engineer

About Us

CopilotKit is the #1 open-source platform for building AI Copilots — intelligent agents designed to work with users inside of real applications. In our first two years, we’ve delivered the fastest growing Javascript AI framework of all time, and built a vibrant community (40k+ GitHub stars, millions of weekly installs, 10s of 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 (including production usage by over 10% of Fortune 500s).

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 hyper-scalers (including the leading AI/infra teams at Google, Microsoft, Amazon, Oracle, LangChain, Mastra, Pydantic, Agno, and others).

Our small, fast-moving team is building the agentic application platform that will define how user-interactive AI actually manifests in the real world. This is a unique opportunity to join as an early leader on one of the most complex and high-leverage surfaces in AI — with significant scope for technical, product, and leadership growth.

The Role

You'll ship fullstack AI applications that showcase CopilotKit's capabilities — creating demos, templates, and starters that developers clone and build on. Your projects are CopilotKit's storefront: polished UI, production-quality code, and READMEs that make it easy to get started.

This role combines rapid prototyping with ecosystem awareness. You'll build demos that land at the right moment, react to new integrations and AI capabilities while they're trending, and set the standard for what "built with CopilotKit" looks like. Because CopilotKit sits at the frontend of the agentic stack, your demos bring our partners' libraries to life — amplified by everyone from Google to AWS to LangChain.

We're Looking for Pilots, Not Just Mechanics

You need to think at the level of systems and outcomes — not just implementation. You're fluent in AI-assisted development as your primary mode of working, using AI coding tools to ship demos from idea to deployment in days. You've shipped meaningful work this way and understand that compelling demos require both technical excellence and good taste.

What You'll Do

  • Ship fullstack AI applications with great UI that showcase CopilotKit's capabilities
  • Create clean, well-documented templates and starters that developers clone and build on
  • React to ecosystem trends: build demos for new integrations, capabilities, and patterns while they're hot
  • Set the standard for production-quality code and polished developer experience
  • Spot opportunities independently and build demos that resonate with the developer community

What We're Looking For

  • Ship fast: Idea to deployed demo in days, not weeks
  • Fullstack and frontend-strong: Build end-to-end with noticeably good UI — clean, modern, polished
  • AI-native workflow: You actively use AI coding tools (Copilot, Cursor, Claude, etc.) to move at speed; you think at the level of systems and outcomes, directing AI to rapidly prototype while evaluating outputs critically
  • Technically curious about AI: Follow the agentic AI space and have opinions about what's interesting
  • High agency: See opportunities to build something resonant and just do it
  • Good taste: Know what makes a demo compelling — not just technically correct, but something developers want to try
We care about what you can build, not resume length. Show us your GitHub. Non-traditional backgrounds welcome.

Why Join Us

Work on foundational AI tech: Build the infrastructure powering the next wave of user-facing, AI-native applications
Ship from zero-to-one: Join early enough to shape the product, architecture, and engineering culture while riding the wave of real traction and momentum
Be surrounded by top talent: Join an A+ team and collaborate with world-class engineers, researchers, and AI infra leaders
Make open-source impact: Build in public with a fast-growing, engaged developer community
Own meaningful upside: Competitive salary and real equity with early-stage ownership and line-of-sight to value creation
Build your network: Daily and weekly work alongside the most important teams of the world’s most important companies; on the infrastructure side, the ai/infra teams of Google, Microsoft, Amazon, Oracle, Langchain, Mastra, Pydantic, Agno, and others; on the customer side, the leading ai product initiatives of the world’s top enterprises
Great benefits: 100% health coverage for employees, 50% for dependents, Dental and Vision insurance, competitive paid time off
Remote-first, high-agency culture: Flexible work, no micromanagement, and full trust and ownership
Help define a new category: Shape the direction of a fast-growing, well-funded startup building a core layer of the future AI stack

We're looking for builders with a bias toward ownership: engineers who thrive in ambiguity, love solving hard problems, and want to help create something genuinely new. You’re joining at the inflection point: product-market fit is real, momentum is strong, and the most meaningful technical decisions are still ahead.
