You will be working at the forefront of enterprise and low latency LAN network design, delivering resilient, best in class architectures that underpin global real time trading and market data systems.
WHAT YOU'LL BE DOING:
- Lead the design, optimisation, and evolution of LAN and data centre networking architectures, including switching, routing, traffic engineering, and segmentation.
- Deliver low latency, deterministic connectivity solutions optimised for real time trading and market data workloads.
- Develop and maintain network topologies, high availability designs, and reference architectures for use across LSEG environments.
- Implement and validate LAN features such as EVPN/VXLAN fabrics, QoS, multicast, and performance tuned network services.
- Serve as a LAN design specialist, guiding engineering teams and contributing to architectural forums, design reviews, and platform roadmap discussions.
- Partner closely with infrastructure, application, and cloud engineering teams to define connectivity requirements and support workload onboarding.
- Provide consultancy and technical direction to teams integrating their services into LAN or hybrid network environments.
- Lead troubleshooting and root cause analysis activities across complex LAN, campus, and data centre connectivity environments.
- Contribute to improvements in observability, monitoring, network telemetry, and performance diagnostics.
- Evaluate emerging LAN technologies, vendors, and design innovations, presenting findings to senior engineering stakeholders.
- Work effectively within an agile, iterative delivery model.
- Balance multiple priorities across a dynamic, fast moving environment.
- Champion high quality engineering standards and ensure designs support resilience, scalability, and security.
WHAT YOU'LL BRING:
- Strong experience in LAN and data centre network design at enterprise scale.
- Deep understanding of Layer 2/3 architectures, including STP variants, MLAG, VLANs, VXLAN/EVPN, BGP, OSPF, and ECMP.
- Proven background in building low latency, high performance network environments (preferably financial services or similarly demanding workloads).
- Strong knowledge of network segmentation, policy enforcement, redundancy design, and high availability strategies.
- Solid understanding of Linux networking, packet flows, NIC capabilities, traffic shaping, and performance tuning.
- Understanding of modern container technologies, particularly Kubernetes.
- Awareness of container networking concepts (e.g., CNI plugins), and how workloads consume network resources in hybrid cloud or on-prem container environments.
- Familiarity with Git-based workflows, CI/CD principles, or automation tooling (Terraform, Ansible, scripting languages).
- Strong communication skills with the ability to translate complex LAN design topics to technical and non-technical stakeholders.
- Excellent analytical and problem solving skills across layered network and infrastructure environments.
- Comfortable working in a fast-paced environment with changing priorities.
