Junior React Native Developer & Community Support

👋 Who are we?

We’re The Widlarz Group, a software house specializing in React Native, actively contributing to the Open Source community. You might already know our work - we’re the team behind popular Open Source libraries like react-native-video.

Our teams - especially the Special Task Force - specialize in performance audits, technical debt assessments, recovery plans, and R&D in the area of native libraries.

We value transparent communication, a shared pursuit of excellence, and the real impact of every team member on our organization’s growth - principles we developed together and live by every day.

We’re building a community, not just a team. We want our collaborators to feel part of something bigger - we co-create projects, contribute to open source, and meet regularly to share knowledge and experience.

We work remotely, but meet weekly in Kraków to share knowledge, plan ahead, and keep our team culture strong.
