About the role
- Joining LSEG as a Lead Engineer to design and optimize enterprise-scale LAN and data centre connectivity. Focused on low latency solutions for global trading systems.
Responsibilities
- 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.
Requirements
- 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 Gitbased 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 nontechnical stakeholders.
- Excellent analytical and problem solving skills across layered network and infrastructure environments.
- Comfortable working in a fastpaced environment with changing priorities.
