Job description

The Opportunity: Grow into a Pro

We are looking for a motivated Junior Fullstack Developer to join our engineering team. This is not a "maintenance" role – you will be working alongside Senior Developers on a production-grade system, learning how to build scalable services in Go and modern interfaces in React.
We value curiosity, strong CS fundamentals, and a "can-do" attitude over years of experience.

Responsibilities

What you will learn & do:

• Fullstack Delivery: Build end-to-end features under the mentorship of Senior Engineers.

• Go Backend: Write clean, performant code in Golang and learn how to handle concurrency and databases.

• Modern Frontend: Develop UI components using React and TypeScript, focusing on state management and performance.

• Best Practices: Get hands-on experience with CI/CD, TDD, and professional Code Reviews.

 Our Tech Stack:

• Backend: Go (Gin/Echo), PostgreSQL, Redis.

• Frontend: React, TypeScript, Tailwind CSS.

• Tools: Git, Docker, GitHub Actions.

Requirements

Must-have

• Solid Foundations: Good understanding of Golang.

• Web Basics: Knowledge of how the web works (HTTP, REST, JSON, DOM).

• React Knowledge: Ability to build simple applications or components in React.

• Database Basics: Basic SQL knowledge (writing simple queries, understanding relations).

• Mindset: Strong problem-solving skills and a hunger for learning new technologies.

• English: Minimum B2

• Portfolio/GitHub: Show us your code! We want to see a project, a bootcamp final task, or an open-source contribution.

• An AI-native mindset: You’re proactive about using tools like Cursor, Codex, or Copilot for test automation.

Nice-to-have

• Basic familiarity with Docker.

• Experience with TypeScript.

• Understanding of what a "Unit Test" is and why it's important.

Benefits

Remote-First Flexibility

Stay where you feel most productive. Here’s a remote-first environment with the freedom to set your own schedule. Whether you need a midday break or a specific routine, we trust you to manage your time and deliver results while maintaining your personal well-being.

In-person Networking

We support autonomy by enabling project groups to set up their own internal meetings in a location they prefer, often in our Poznań or Gliwice offices, which are great for coordination and building professional relationships. We also take a break from our screens twice a year for our Summer and Winter events.
