About Codesphere
Codesphere is a Virtual Cloud Provider from Germany building the future of sovereign cloud infrastructure. Our platform gives enterprises and governments full sovereignty without giving up modern cloud capability – a vision recently validated by a series of multi-million European government tenders.
Since our founding in Karlsruhe in 2020, we’ve expanded into an international team of 60+ experts. Based in Karlsruhe and Munich and backed by top-tier investors, we are chasing a bold vision.
We’re scaling fast and would love for you to join us and grow alongside us 🚀
What you’ll drive
•
You own complex features end to end – from product discovery and planning through technical design, implementation, testing, and maintenance.
•
You conduct code and technical design reviews, raising the bar for quality across the team.
•
You mentor junior engineers and actively contribute to a culture of learning and growth.
•
You shape the capabilities of our collaborative developer cloud, working on features that improve the overall platform experience – including Public API, Usage History, IAM & Permission Management, Secrets Management, external CI integrations, Web IDE, deployment technology, monitoring, managed services, and the core internals of customer application deployment.
