These include 3rd-party technologies as well as bespoke workflow enhancements.

Responsibilities

• Design and enhance Kubernetes provider platforms and supporting infrastructure to improve scalability, reliability, and developer experience.

• Automate and simplify Kubernetes clusters lifecycle management, upgrades, and observability workflows.

• Implement monitoring and alerting systems using tools such as Prometheus, Grafana, or Elastic Observability to meet service-level objective (SLOs).

• Collaborate with security teams to integrate and enforce security controls and compliance requirements within the container platform.

• Work with application teams to improve platform usability, streamline onboarding, and reduce operational toil.

• Respond to incidents and perform post-incident reviews, driving continuous improvement and operational excellence.

• Contribute to the reliability engineering culture, fostering shared responsibility for system availability and performance.

Requirements (Minimum Qualifications)

• A degree or professional qualification in Computer Engineering, Computer Science or related field

• Strong programming or scripting experience (e.g. Git, Terraform, Javascript, Python, or Bash)

• Good understanding of Linux systems, containers, and networking fundamentals.

• At least 1-3 years of hands-on experience operating or managing Kubernetes clusters in production environments.

• Experience implementing observability and monitoring in large-scale systems.

Good to Have

• Knowledge of Kubernetes security concepts such as RBAC, admission controllers, and policy enforcement.

• Experience with GitOps workflow and deployment tools (e.g. ArgoCD, Gitlab Runner)

• Understanding of service mesh technologies (e.g. Istio)

• Exposure to reliability engineering practices, including SLOs, error budgets, and capacity planning

• Familiarity with cloud platforms (AWS, GCP or Azure) and hybrid infrastructure architectures

• Knowledge of networking protocols (HTTP, TCP, DNS) and troubleshooting tools

• Passion for open-source technologies
