Kotlin Developer (Senior/Staff)

We are SoftwareMill and in 2023 we were acquired by VirtusLab. Since then we are cooperating closely, working together for clients across the globe. At the same time we remain a separate organisation with own culture and processes.

At SoftwareMill we are a diverse group of individuals: passionate geeks, humanists, fantasy and karate fans, Apple and Android enthusiasts. It’s our differences, along with the values we share, reliability, and strong experience, that empower us to build one of the most employee-friendly companies in the IT industry.

And it’s not just our opinion ,our unique culture has earned us the title of Poland’s Best Workplace in the 50–99 employees category, awarded by Great Place to Work. We collaborate 100% remotely (no office since day one), from homes spread across Poland (and beyond)!
