Senior Software Engineer, Platform & Infrastructure (all genders)

We are a leading SaaS provider in our field and operate a large number of customer
environments in our cloud. To ensure that these environments run smoothly, we are looking for
you! Together with your colleagues on the Platform & Infrastructure team, you will be
responsible for the scalability, security, and efficiency of our cloud infrastructure — covering
AWS, Kubernetes, observability, and the internal developer platform that our product teams build
on. We ship continuously — on average 150 deployments to production every month — and
your work is what keeps that pace fast, safe, and sustainable. You will actively contribute to
shaping our technical roadmap, mentor engineers around you, and help cultivate a progressive
and learning environment.

Must-have

• 5+ years of professional engineering experience, including 3+ years in infrastructure, platform, or site reliability engineering
• Deep hands-on experience with Kubernetes: cluster operations, workload management, troubleshooting at scale
• Helm chart authoring: writing, packaging, and maintaining charts — not just consuming them
• GitOps experience with Argo CD or an equivalent tool (Flux, etc.)
• Working knowledge of AWS (EKS and supporting services such as IAM, VPC, RDS, S3)
• Experience with Infrastructure as Code (Terraform or equivalent)
• Proficiency in Go or Python — we write custom operators and internal tooling in both
• Experience owning production incidents end-to-end — response, mitigation, and postmortem
• Strong English communication skills, with the ability to explain technical decisions to both engineers and non-technical stakeholders

Nice-to-have

• Kubernetes operator development experience (Kubebuilder or similar)
• Progressive delivery tooling (Kargo, Argo Rollouts, or equivalent)
• Policy-as-code experience (Kyverno or OPA)
• Runtime security tooling (Falco or equivalent)
• Familiarity with observability tooling (Grafana, OpenSearch/Elasticsearch, or equivalent)
• Experience with CI/CD pipelines (GitLab CI preferred)
• Experience mentoring engineers or participating in technical hiring
• German language skills (helpful for customer site interactions)

On-Call
