Offer description
Join probably the biggest Flutter Team in Poland !


LeanCode is a software studio based in Warsaw (Poland). We are a team of 57+ 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 the SaaS solutions. This gives our team plenty of room to explore new business and master challenging domains.

We work for companies from all over the world (at the moment, that is: Poland, Germany, UK, 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 like. 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 the 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 with each other. 

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


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