Senior DevOps Engineer

We are expanding our Barcelona office with a Senior Dev Ops Engineer!

As a Senior Dev Ops Engineer within the Cloud team, you will be responsible for building and maintaining the infrastructure that powers Fast Track ay, we operate hundreds of brands across dozens of Kubernetes clusters on AWS, and our ambition is to turn infrastructure into a competitive advantage, not a bottleneck.

To be successful in this role, you will need strong hands‑on experience with AWS, Kubernetes, and Infrastructure as Code, and you should enjoy working on automation that makes a real difference to how teams ship and operate software.

You won’t just maintain what exists. You’ll help drive the next phase of our cloud operations: improving the current Git Ops workflow, automating the environment lifecycle, enhancing our CI/CD pipelines, and making our infrastructure more observable, cost‑efficient, and resilient.

• Remove any manual provisioning steps from the environment lifecycle
• Consolidate, standardise IaC modules across all clusters and accounts
