Job description

Overview

Qube Research & Technologies (QRT) is a global quantitative and systematic investment manager, operating in all liquid asset classes across the world. We are a technology and data driven group implementing a scientific approach to investing. Combining data, research, technology and trading expertise has shaped QRT's collaborative mindset which enables us to solve the most complex challenges. QRT's culture of innovation continuously drives our ambition to deliver high quality returns for our investors.

Your future role within QRT

We are building a new team and are 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.

Your present skillsets

• Help design and lead the implementation of 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.
