ROLE SUMMARY:
If you’re a network engineer who loves solving hard problems and wants your skills to matter at platform scale, this role is built for you. You’ll be working in the Containers, Integration, and Network Connectivity product space, shaping a next‑generation, ultra‑low‑latency, cloud‑native container platform that underpins real‑time market data services globally.
This is not “keep-the-lights-on” networking — it’s hands‑on engineering where IP routing and network services, cloud‑native networking, and modern Kubernetes networking (including EKS and Cilium/CNI) directly impact performance, resilience and how applications connect, scale and operate across hybrid environments.
You’ll partner closely with architects and product owners to influence platform networking capabilities end‑to‑end, while building, automating and evolving the service as code in a highly technical, collaborative engineering culture.
As well as a proven technical background, the ideal candidate must be able to participate effectively in multi-functional meetings, clearly articulate sophisticated technical and capabilities, translate business requirements into technical requirements, and ultimately, into outcomes that are fit for purpose and use. Collaboration is key, as you will be helping LSEG to deliver all the platform infrastructure build, configuration, tooling, observability, and lifecycle management activities as code.
WHAT YOU'LL BE DOING:
Owning the production operation of Kubernetes and hybrid cloud platforms, including reliability, performance and stability.
Implementing and evolving monitoring, alerting and observability across Kubernetes clusters and supporting infrastructure.
Analysing platform behaviour under load, identifying risks and driving proactive improvements.
Supporting incident response, root cause analysis and post‑incident actions for Kubernetes‑based services.
Partnering with platform engineers and application teams to ensure production readiness and smooth onboarding.
Improving automation, runbooks and operational tooling to reduce manual intervention.
Acting as a Kubernetes production SME, advising on best practice and operational standards.
Influencing platform roadmaps through data‑driven operational insights.
WHAT YOU'LL BRING:
Strong real‑world engineering experience (not purely theoretical), with a genuine appetite to learn, experiment and deepen expertise in modern platform and networking technologies.
Deep networking fundamentals, including hands‑on experience with IP routing, traffic flow, latency and network services, and the ability to reason clearly about how connectivity and performance behave across complex, multi‑layered systems.
Proven experience operating or engineering Kubernetes and container platforms in production, with particular focus on networking inside Kubernetes environments — such as CNI (e.g. Cilium), network policies, ingress/egress, and east‑west traffic patterns.
Cloud and hybrid networking experience, ideally within AWS/EKS environments, including familiarity with VPC design, routing, security controls, and on‑prem to cloud connectivity, and how these choices impact platform performance and resilience.
Strong Linux experience (preferably Ubuntu), with confidence troubleshooting systems end‑to‑end — particularly in performance‑sensitive or latency‑optimised environments.
An automation‑first mindset, with hands‑on experience using Terraform, Ansible, scripting and Git‑based workflows to build, configure and manage infrastructure and networking as code.
Experience working with CI/CD pipelines, automated testing and modern delivery practices to safely evolve platform and networking capabilities at scale.
The ability to diagnose and resolve complex issues across networking, Linux and Kubernetes layers, working collaboratively with platform engineers, vendors and tenant teams.
Strong communication skills, including the ability to articulate technical topics clearly to architects, product owners and senior stakeholders, and translate business requirements into practical, network‑aware platform solutions.
Comfort operating in fast‑paced, evolving environments, where priorities may shift and engineers are expected to take ownership, apply good judgement and deliver high‑quality outcomes.
