Job description

Location: Berlin, Germany (office first)

Our Platform Tribe builds Fleet, the infrastructure foundation that every engineering team at SumUp relies on to ship safely and quickly. Fleet gives teams a stable, self-service platform, built on AWS, Kubernetes and Terraform, so they can focus on their products instead of infrastructure bottlenecks. As part of the Cloud Infrastructure team, you'll take ownership of critical platform services, help modernise how we run Kubernetes at scale, and support engineers across the business as they build on top of what you maintain. If you enjoy solving complex infrastructure problems that quietly power everything else, this is where that work happens.

What you'll do

Design and maintain Terraform modules and infrastructure patterns that other engineering teams build on

Manage production Kubernetes (EKS) clusters, including performance tuning and service mesh implementation

Lead security and compliance work across frameworks such as PCI DSS and SOC2, partnering with the Security team

Define and monitor service reliability metrics, take part in on-call rotation, and drive improvements after incidents

Improve developer experience through automation, better CI/CD pipelines, and clearer documentation

Mentor other engineers on the team and contribute to technical design discussions

You'll be great for this role if…

At least 8 years of experience in DevOps, platform, or infrastructure engineering

• Proven hands-on experience in software development (Go preferred, but anyone would be good)

Experience designing and maintaining infrastructure as code, ideally with Terraform

Strong knowledge of Kubernetes in production, including cluster operations and troubleshooting

Hands-on experience with core AWS services such as EC2, VPC, IAM, and load balancing

Comfort working within security and compliance requirements without slowing teams down

Ability to mentor other engineers and explain technical decisions clearly to different audiences

• A corporate pension scheme where we match up to 20% of your contributions
• Generous time off: enjoy 28 days of paid leave plus public holidays and special leave days
