Engineering

Full-time

hybrid

Our vision is simple yet powerful: we want to create a place where engineers thrive, taking on exciting projects and using the latest technologies, free from the shackles of legacy solutions.

Thanks to the diverse range of industries we work with, our days are never boring: from world-class apps to AR solutions or even programming robots, we’ve got it all covered. We don’t just write code for our screens; rather, we develop impactful products used by millions every day: let them be large-scale public transport applications, leading fintech platforms, or storage solutions contributing to a greener future.

We are a team of 100+ engineers (Java, JavaScript, Android, iOS, NodeJS and dotnet platforms) and QA engineers with our coding fingers at the ready working on the next big thing. We value openness, modesty, hard work, and simple yet great solutions.

We’re looking for a Lead Backend Engineer who enjoys shaping both systems and people. In this role, you’ll lead a Java/Kotlin backend team, set technical direction, and stay close to delivery by contributing hands-on when it matters. You’ll balance architecture, code quality, and engineering best practices with line management, mentoring, and team development, while collaborating closely with Tech Leads, Architects, and client-facing teams.

This is a role for someone who likes ownership, long-term impact, and building teams that scale as well as the systems they work on.
