Responsibilities :

As they build a new team, this firm is seeking experienced Kubernetes Engineers who can support both cloud-based and on-premise container orchestration platforms. This role will contribute to the stability, scalability, and performance of our Kubernetes clusters, supporting a variety of mission-critical workloads. You will work closely with cloud, DevOps, and application teams to ensure smooth deployment pipelines, robust observability, and secure cluster operations.

Requirements :

• Help design and lead the implementationof Kubernetes clusters (on-prem and / or cloud) with high availability, scalability, and security.
• Offer Kubernetes as a product to internal teams by delivering self-service capabilities (e.g. namespace provisioning, templated jobs, onboarding flows).
• Build reusable platform patterns and deployment blueprints using Helm, Kustomize, or custom controllers.
• Develop and maintain platform-aware GitOps workflows using tools like ArgoCD, Flux, and GitLab CI.
• Design tenancy-aware RBAC, network policies, and secrets management aligned to internal standards and developer autonomy.
• Deep understanding of Kubernetes internals, including control plane components, CRDs, CNIs, and storage provisioning.
• Apply policy-as-code via admission controllers (OPA / Gatekeeper) to enforce compliance and enable safe multi-tenancy.
• Implement observability stacks that monitor cluster health, workload status, and policy violations, exposing this to users through dashboards or APIs.
• Manage and support Kubernetes clusters across production, staging, and development environments.
• Troubleshoot and resolve infrastructure, container, and networking issues in Kubernetes environments, while shifting common operational tasks into automation and developer-friendly tooling.
• Support application teams with onboarding and deployment by enabling paved-path workflows—not ticket-based operations.
• Participate in on-call rotation and incident response related to Kubernetes and containerised applications.
• Demonstrable knowledge of Python, Golang, or similar languages, with emphasis on platform tooling, scripting, or controller development.
• Stay informed on industry trends and emerging technologies to evolve platform capabilities, developer experience, and operational resilience.
