About LeanCode

Join probably the biggest Flutter Team in Poland.

LeanCode is a software studio based in Warsaw (Poland). We are a team of 60+ skilled developers, UX designers, and product owners. Our mission is to solve real-life problems using cutting-edge technologies.

Our clients represent different industries, from banking and insurance through retail and MedTech products up to SaaS solutions. This gives our team plenty of room to explore new businesses and master challenging domains.

We work for companies from all over the world (at the moment, that is: Poland, Germany, the UK, the USA, and Australia).

We join forces with the clients at the very early stage of the process. Thanks to that, we have a substantial impact on how our products actually work and look. This approach requires very close cooperation with the clients, including frequent workshops and day-to-day meetings with them.

We contribute a lot to the Fluttervese. We co-organized the biggest Flutter conference in the world - Flutter Europe. We also run Flutter Warsaw Meetup, which gathers hundreds of Flutter enthusiasts during monthly online events. What is more, we are taking our first steps as open-source contributors. In our internal Flutter Guild, we already have 22 Flutter Developers who weekly share their knowledge

When joining LeanCode, you can count on a full onboarding process and equipment, including the newest M1 CPU.

We are looking for a Flutter Developer, a team player who cares not only about beautiful layouts but also about great user experience, software architecture, and code quality

There’s a catch in this offer, though… You’ll probably have to learn how to play table soccer or table tennis if you join us ;)
