As a Kubernetes Production Engineer, you will focus on running Kubernetes at scale in production - ensuring clusters, networking, and supporting services are reliable, observable and fit for purpose under real-world load. You will work closely with platform build teams, architects and application owners to harden platforms, improve operational tooling, and ensure services are production-ready before and after go-live. This is a hands-on engineering role for someone who enjoys working close to live systems, diagnosing complex behaviours in distributed environments and continuously improving how Kubernetes platforms are operated. The ideal candidate is comfortable in fast-paced environments, thrives on problem-solving and brings a strong production mindset rather than a purely development or design focus. WHAT YOU'LL BE DOING: * Owning the production operation of Kubernetes and hybrid cloud platforms, including reliability, performance and stability. * Implementing and evolving monitoring, alerting and observability across Kubernetes clusters and supporting infrastructure. * Analysing platform behaviour under load, identifying risks and driving proactive improvements. * Supporting incident response, root cause analysis and post-incident actions for Kubernetes-based services. * Partnering with platform engineers and application teams to ensure production readiness and smooth onboarding. * Improving automation, runbooks and operational tooling to reduce manual intervention. * Acting as a Kubernetes production SME, advising on best practice and operational standards. * Influencing platform roadmaps through data-driven operational insights. ## Related Videos - [One Platform Could Not Fit Them All](https://www.wearedevelopers.com/videos/1919-one-platform-could-not-fit-them-all) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [WeAreDevelopers LIVE - Modern DevOps for IoT Devices and More](https://www.wearedevelopers.com/videos/1805-wearedevelopers-live-modern-devops-for-iot-devices-and-more) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [GitOps for the people](https://www.wearedevelopers.com/videos/815-gitops-for-the-people) - [Are Code Reviews Worth It?
