LSEG (London Stock Exchange Group) is a diversified global financial markets infrastructure and data business, dedicated to delivering open‑access services that enable customers to manage risk and create jobs.
Role Summary
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.
What you’ll be doing
Engineering & Delivery
- 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.
Technical Influence & Collaboration
- 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.
Operational Excellence
- 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.
Ways of Working
- 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.
What you’ll bring
- 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 (GitLab, 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.
