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 ## Related Videos - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [5 steps for running a Kubernetes environment at scale](https://www.wearedevelopers.com/videos/88-5-steps-for-running-a-kubernetes-environment-at-scale) - [Debugging in the Dark](https://www.wearedevelopers.com/videos/1658-debugging-in-the-dark) - [Monoskope: Developer Self-Service Across Clusters](https://www.wearedevelopers.com/videos/329-monoskope-developer-self-service-across-clusters) - [Software Engineering Social Connection: Yubo’s lean approach to scaling an 80M-user infrastructure](https://www.wearedevelopers.com/videos/1583-software-engineering-social-connection-yubo-s-lean-approach-to-scaling-an-80m-user-infrastructure) - [Delegating the chores of authenticating users to Keycloak](https://www.wearedevelopers.com/videos/1558-delegating-the-chores-of-authenticating-users-to-keycloak) ## Related Articles - [Backend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/196-backend-developer-salary-in-germany-2023) - [Fullstack developer salary in Germany [2023]](https://www.wearedevelopers.com/magazine/197-fullstack-developer-salary-in-germany-2023) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Frontend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/195-frontend-developer-salary-in-germany-2023) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again)
