We are looking for someone with strong experience in DevOps and at least in one of the following areas: Java back‑end development, React/Nextjs or cloud technologies such as Kubernetes, ArgoCD, AWS and Terraform.

A selection of your key result areas

• Build and maintain CI/CD pipelines and infrastructure using Terraform, Kubernetes and AWS
• Take ownership of our products and services built with Java and Spring Boot React and/or Nextjs within a MACH‑based ecosystem;
• Be responsible for the full lifecycle of services, development, deployment and production operations

• Integrate custom backend services with a commercial off the shelf e‑commerce platform
• Ensure high code quality through testing, reviews and pragmatic standards
• Contribute to security related topics by identifying risks and improving implementations

• Strong experience with Java and Spring Boot and/or React/Next.js, combined with solid experience in at least one other technical domain.

If you enjoy taking ownership, working with modern technology and building software that genuinely matters to the business, we’d love to have you on the team.
