  • Responsibility for operating high-availability, redundant and complex distributed systems governed by the CAP-theorem to support highest non-functional requirements, e.g. for online banking, trading and reporting or medical systems


  • You love designing, building and operating mission critical systems that require no nightly attendance due to their high quality, resiliency and robustness
  • Healthy interest in trying out new concepts and technology, especially for infrastructure abstraction
  • Embrace change and have a cloudnative mindset
  • Have a good understanding of the merrits of centralized logging, monitoring, alerting, tracing, deployments and configuration management
