Product Developer (React + AI)

We're building products at the intersection of developer experience and AI. MCP Gateway, GenSDK, and AuthLane are starting to gain traction, and we need someone to help push them forward. One day you're shipping a new feature in React, the next you're shaping with the product owner what it should look like. We're looking for a developer who wants to not just code, but think about the product.

What will your job be

You'll develop and grow our products. AI tools aren't nice-to-have, they're the foundation of your workflow.

• MCP Gateway: Centralized AI profile management with compliance logging (NestJS, Prisma, MCP SDK). New features and solving real use cases.
• GenSDK: Automatic SDK generation across languages. Development and improvements.
• AuthLane: OAuth management platform for SaaS developers.
• DX Heroes website: Minor adjustments and new content.
• AI-first development: We expect you to actively use Claude Code, Cursor, or similar tools. You don't write everything by hand, AI is your copilot.

What we expect from you

• React + TypeScript, a solid foundation, you don't need to be a senior.
• Tailwind CSS, practical experience.
• Ability to ship: Pick up a task from GitHub Issues and get it done, without hand-holding.
• Product thinking: Not just how to build it, but why we're building it and for whom.
• AI-assisted development: Active use of Claude Code, Cursor, Copilot, or similar tools.
• Bonus: NestJS, Prisma, experience with the MCP protocol.
• You don't need to check every box. If this sounds interesting, reach out.

Who you'll work with 👥

On a small team you'll be in direct contact with Prokop (CEO and product owner), architect Jakub Vacek (Applied AI Architect), who designs agentic systems and LLM integrations, and Matyáš, who co-builds MCP Gateway. Short feedback loops, fast iterations.

Why join us? 💜

You'll work on real products that people use, not internal tooling that sits in a drawer.

• Real products: Our tools solve a genuine problem around AI and developer experience.
• AI-first culture: AI isn't a buzzword here, it's a tool you use daily.
• Direct collaboration with the CEO and product owner: Short feedback loops, fast iterations.
• Modern stack: React 19, TypeScript, Tailwind, NestJS, Prisma, Vite, Turborepo.
• Flexibility: Remote and part-time, organize your work as you like.
