Senior Software Engineer, Platform & Infrastructure (all genders)

Your role

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.

Your mission

• Own and evolve our Kubernetes platform across multiple clusters: manage Helm chart deployments via an OCI registry hosting 40+ charts, enforce policy-as-code with Kyverno, and operate GitOps workflows through Argo CD ApplicationSets with progressive delivery orchestrated by Kargo
• Drive technical designs for platform initiatives: scope the problem, propose multiple solutions, assess their trade-offs, and defend your recommendation — then see it through to production
• Harden the platform's security posture: workload identity via OIDC, runtime security, image scanning and secrets management
• Write and maintain custom Kubernetes operators and internal tooling in Go and Python that multiply the team's leverage across clusters — we run Zalando postgres-operator alongside our own operators
• Maintain and improve our observability stack (Prometheus, Grafana, Thanos, OpenSearch): build dashboards and alerts that give product teams real visibility into their services
• Keep GitLab CI/CD pipelines fast and reliable — they power ~150 production deployments per month; execute cross-team changes (rollouts, database migrations, certificate rotations) with care and clear communication
• Operate and evolve AWS infrastructure (EKS, VPC, IAM, RDS, S3) including dedicated customer environments in their own AWS accounts; drive cost-efficiency initiatives tracked via OpenCost
• Own incidents end-to-end: from alert to fix to postmortem
• Raise the team's bar through thorough code and architecture reviews, mentor less experienced engineers, and help us assess technical candidates in interviews
• Be the infrastructure partner product teams come to when things are unclear or broken
• Participate in a shared on-call rotation

Your profile

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
You'll participate in an on-call rotation. Incidents require fast response and clear communication. On-call burden is tracked and addressed through rotation and capacity planning.
