Our customers include the world's leading public cloud and silicon providers, and industry leaders in many sectors. The company is a pioneer of global distributed collaboration, with 1200+ colleagues in 75+ countries and very few office-based roles.

We are hiring a Software Engineer on the Core Desktop team. In this role, you'll join a dedicated team of professionals to build the next generation of immutable Ubuntu desktop.

In this project we combine the best ideas of immutable Linux with the latest Linux desktop experience to bring our global ecosystem of developers a much better platform for innovation. We mostly code in system languages such as C / C++ and use Python and Shell scripting as well. Occasionally we use Go, and Dart / Flutter. This role offers a unique opportunity to grow and learn in a fast‑paced environment. Your contributions, guided by more experienced team members, will be essential in shaping the future of Ubuntu's Core Desktop.

Location : This is a home‑based position on a team in the EMEA region.
