Our mission:

Are you a motivated experienced person, used to working in an international multi-cultural environment, who really wants to make a difference in the open-source world?

We believe it’s crucial to work in an environment where people feel valued, are energized by their work and deliver added value.

• Own and improve packaging and release engineering processes, ensuring consistent, automated, and high-quality product distribution.
• Enhance internal testing frameworks, increase coverage, and contribute to the overall reliability and quality of the system.
• Provide Level-3 engineering support, diagnose complex issues across the stack, and collaborate with operations to ensure stable cloud-hosted deployments.
