This is an exceptional opportunity to join a high‑impact engineering team delivering the next generation of LSEG’s latency‑optimised, real‑time market data platforms. You will work on Kubernetes platform engineering, shaping a hybrid‑cloud container ecosystem for globally consumed infrastructure services.

• Contribute to the design, implementation, and enhancement of Kubernetes‑based container platform components, focusing on CNI, networking, and cluster‑level integrations.
• Lead delivery of engineering tasks for Kubernetes platform features across development, test, and production environments.
• Implement, configure, and validate CNI solutions (e.g., Cilium), network policies, and associated platform capabilities.
• Drive high‑quality engineering practices including testing, documentation, peer reviews, and CI/CD automation.

• Act as a domain specialist in Kubernetes and CNI networking, guiding team members and partnering with adjacent engineering squads.
• Provide technical input into platform architecture, backlog refinement, and feasibility assessments.
• Assist application teams onboarding to the container platform, providing guidance on networking, cluster usage, and deployment patterns.

• Support troubleshooting and root‑cause analysis across multilayered network and container environments.
• Contribute to platform reliability and observability improvements through dashboards, run‑books, and automation.
• Evaluate new tools, technologies, and approaches and present findings to the wider engineering community.

• Operate effectively in an agile, iterative delivery model.
• Manage multiple work streams and priorities in a dynamic environment.
• Uphold engineering standards and advocate for platform quality, stability, and scalability.

• Hands‑on Kubernetes engineering experience in production environments, building, operating, and evolving cluster‑level capabilities.
• Strong experience writing production‑grade automation and tooling in Go, particularly for Kubernetes‑related components (e.g., operators, controllers, extensions).
• Solid understanding of Linux networking fundamentals and container networking internals.
• Working knowledge of Kubernetes deployment pipelines, Git‑based workflows, and automated testing principles.
• Strong recent Linux (especially Ubuntu) experience.
• Exposure to monitoring, observability, and troubleshooting across containerised workloads.
• Familiarity with CI/CD tools (Git Lab, Jira, Confluence).
• Experience with automation tools such as Terraform, Ansible, or scripting languages.
• Understanding of performance‑tuned or latency‑sensitive environments (preferred but not required).
• Strong analytical, problem‑solving, and communication skills in complex system environments.
• Ability to collaborate effectively across teams and communicate technical concepts clearly.
• Comfortable working in a fast‑paced environment with evolving priorities.
