This is NOT a traditional developer role.
We’re not looking for someone who writes code all day — we’re looking for someone who leads AI agents that write code for you.

This is not “a regular dev job with an AI assistant”.
This is a role for a person who thinks in systems, prompts, and outcomes, not in endless manual coding.

About us

We are a group of companies with 30+ active projects across travel, fintech, mobile apps, and AI products.
We build products through AI agents, and we’re looking for someone who knows how to work with them effectively.

Tech stack:

• Frontend: Next.js, React Native
• Backend / Infra: Vercel, Firebase, Cloudflare

What you’ll do

• Translate product and technical ideas into clear tasks for AI agents
• Guide AI agents to produce production-ready code
• Review, refine, and improve AI-generated code
• Choose the right models and tools for each task
• Push features all the way to production

In short: you manage an AI-powered dev team that writes code for you.

What we’re looking for

• 1+ year of web development experience
• 3+ months of hands-on work with AI coding tools
• Experience working with AI agents (not just autocomplete)
• Ability to read code and do code reviews
• Solid understanding of frontend, backend, and APIs
• Advanced English

Nice to have

• Built projects mostly or fully using AI
• Know how to optimize AI usage for cost and limits
• Actively follow new models and AI dev tools
• Experience with mobile development

What we offer

• 🏢 Office-based role in Warsaw
• 🤖 Unlimited access to top-tier AI models
• 🎯 Direct collaboration with the CTO — no bureaucracy

How to apply

Please include:

• Examples of projects you built using AI
• Your AI setup: tools you use and how you handle limits and costs
• If you’ve only worked with Cursor — what doesn’t work for you in it?

🚀 If you want to build fast, experiment, and shape how products are created with AI — we’d love to hear from you.
