Job description

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.

YOUR PROFILE

  • Several years of professional experience in software development, ideally in web or distributed systems
  • Strong proficiency in JavaScript/TypeScript and/or Go
  • Solid understanding of SQL databases, distributed systems, and the design of APIs and microservices architectures, containerization e.g. Docker, Kubernetes
  • Degree in a relevant field or comparable qualification
  • Strong foundations in Computer Science fundamentals
  • Professional proficiency in English, written and spoken
  • Strong communication skills and a collaborative mindset
  • Openness to feedback and a genuine drive to keep learning
  • Structured approach to problem-solving and a curiosity for technology

WHAT SETS YOU APART

  • Experience with cloud infrastructure, ideally in a cloud-native environment
  • Familiarity with React
  • Experience building or operating monitoring and logging systems
  • DevSecOps mindset and hands-on experience

WHAT'S IN IT FOR YOU

  • 32 days of paid time off – 30 regular vacation days plus Christmas Eve and New Year's Eve off
  • Meal allowance – up to 15 digital vouchers per month, adding up to over €100 net for you
  • Flexibility – hybrid work setup with mobile work options and flexibility around core hours
  • Steep learning curve – fast-moving environment, real ownership, and a front-row seat to scaling a company
  • Job-Rad – lease a bike through us, tax-free
  • Gym access – stay active on site (Karlsruhe office only)
  • Employee events – from team offsites to regular get-togethers
  • Company pension scheme – company-supported pension to set you up for later
  • Great public transport links – both offices are within walking distance of tram and metro stops
