Job description

Full Stack Junior Developer (Python + TypeScript/React)

Ready to Start Your Career Building Software the AI-First Way?

Most “junior” roles are about fixing bugs in legacy code and waiting for someone to tell you what to do. That’s not us.

We’re an AI-First Development Studio building production-grade systems faster than traditional teams by integrating LLMs and automation into the full development lifecycle — from scoping and planning, through implementation and testing, all the way to deployment and monitoring.

We build AI-driven solutions for one of Poland’s largest privately held companies — and we’re scaling these capabilities to help other organizations modernize how software gets shipped.

If you want to learn modern full-stack development the way the industry is heading, this role is built for that.

What Makes This Role Special

You’ll join a small, fast-moving team where you’ll ship real features to production — not “practice tasks.”

You’ll learn how to build modern web applications with Python + React (or similar), while also getting hands‑on with AI-assisted development every day: using tools like Copilot/Codex-style assistants, structured prompting, automated code reviews, and workflow automation to move faster and write better code.

This is a junior role — but it’s not passive. You’ll be supported with mentorship, code reviews, and clear ownership so you can grow quickly.

What You’ll Be Doing

• Build and improve backend services in Python (FastAPI or similar frameworks)
• Develop responsive user interfaces in React (or similar: Next.js, Vue, Svelte)
• Implement and integrate REST APIs between frontend and backend
• Use AI coding tools to speed up delivery while keeping code quality high
• Write and maintain automated tests (unit/integration, where it makes sense)
• Participate in code reviews and learn modern engineering practices
• Collaborate with product, design, and senior engineers to ship features end-to-end

What We’re Looking For

Junior-Friendly Must-Haves (Skills You’ll Use Daily)

• Good fundamentals in Python (you can build small apps, read existing code, debug issues)
• Some experience with frontend development (React preferred, but “React-like” is fine)
• Understanding of how APIs work (requests, responses, auth basics, JSON)
• Familiarity with Git and a collaborative workflow (branches, PRs, reviews)
• A learning mindset: you enjoy improving fast and you ask good questions

Nice to Have (We’ll Help You Level Up)

• TypeScript experience (or willingness to learn it)
• Any exposure to FastAPI, Django, Flask, or async Python
• Basic knowledge of cloud concepts (AWS/GCP), CI/CD, Docker, serverless
• Comfort using AI assistants (Copilot/Codex-style tools) responsibly and effectively

Who You Are

We don’t expect you to know everything. We do expect you to take ownership of your growth.

You’re someone who is:

• Curious — you like learning new tools and trying better approaches
• Pragmatic — you focus on shipping working software, not perfect theory
• Collaborative — you communicate clearly and welcome feedback
• Driven — you want to become a strong full-stack engineer, fast

What We Offer

The Opportunity

• A real junior role with real production impact
• Mentorship, code reviews, and support from experienced engineers
• Daily exposure to AI-first development workflows that most teams aren’t using yet
• The chance to work on systems used by thousands — and learn how they scale

Professional Growth

• A clear path to leveling up (Junior → Mid) with increasing responsibility
• Learning by doing: features, releases, debugging, performance, testing
• Hands‑on experience with modern tooling, automation, and best practices
• Based in Kraków
• Fast, non-bureaucratic culture — you’ll ship, learn, iterate
• High autonomy with strong support
• Access to high-quality AI tools and infrastructure

Ready to Launch Your Full-Stack Career?

If you want to build software in a team where AI-first is the default, not the experiment — we want to meet you.

We’re an equal opportunity employer committed to building a diverse and inclusive team. All qualified applicants will receive consideration regardless of race, religion, gender, sexual orientation, age, disability, or any other protected characteristic.
