Join our passionate and collaborative Quality Assurance team, dedicated to maintaining exceptional product quality. Our mission is to integrate quality into every stage of the development lifecycle. We promote best practices and work closely with development, product, and design teams to deliver outstanding user experiences. The team fosters a culture of continuous learning, innovation, and technical excellence—empowering each member to make a meaningful impact.

About the Role

As a QA Engineer, you’ll ensure quality across the full technology stack—from backend services to the user-facing client. You’ll design test plans, perform various testing techniques (including API and database validation), and manage defects for integrated features. Working closely with both frontend and backend developers, you’ll verify data integrity, test integrations, and drive quality improvements. You’re expected to operate independently, manage your workload efficiently, and actively enhance end-to-end testing processes.

This position is based in Gdansk - 3 times per week in our Product Madness office (al. Grunwaldzka 50).
