We're hiring a Network Engineering Lead to own the design, evolution, and day-to-day operation of a multi-business production network. The environment spans ultra-low-latency trading paths, high-capacity and highly-redundant data movement, and connectivity to a wide range of external counter-parties across private and public networks.

This is an Individual Contributor role with tech-lead authority. You'll set technical direction, mentor a senior engineer reporting to you, and stay deeply hands-on with the gear. You'll work alongside a fully-staffed data center operations team that handles on-site work and tier-1 incident response — your focus is design, complex troubleshooting, and where the network goes next.

The network is brownfield: a working production fabric carrying real workloads. Your mandate is to take it to the next generation — tighter latency where it matters, more capacity and resilience where it matters, and a meaningfully better automation platform across the board.

• Own end-to-end network design and evolution — from layer-1 optics through routing, segmentation, and overlays.
• Operate a heterogeneous fabric: ultra-low-latency trading paths alongside redundant, high-bandwidth data planes and multi-tenant connectivity.
• Take our network automation to the next level. Drive the move toward a clean source of truth, CI/CD for network configuration, automated validation, and tooling your team will actually want to use.
• Manage and grow connectivity to exchanges, brokers, market-data providers, and other counter-parties — across proximity-hosted, colocated, and private/public network paths.
• Design and operate firewalls and segmentation across multiple security zones.
• Lead complex troubleshooting. Issues that escalate past tier-1 support land with you. Move fast, root-cause, and write it up.
• Set technical direction for the network: own the architecture roadmap, run design reviews, drive postmortems, and partner on hiring as the team grows.
• Mentor a senior engineer reporting to you. Raise the bar on review quality, change discipline, and engineering practices.
• Share a 24/7 on-call rotation with your direct report. Routine, known-solution incidents are handled by support staff.

• 10+ years operating production network infrastructure in environments where uptime and performance are first-order concerns.
• Strong end-to-end understanding of how networks actually work — every layer, not just the ones you touch most often.
• Deep hands-on experience with Arista and Cisco switching and routing platforms.
• Fluency with the protocols this environment runs on: BGP, OSPF, PIM-SM and IP multicast, VLAN, VXLAN, IPSec.
• Experience operating modern data-center fabrics — spine-leaf topologies and EVPN-VXLAN overlays.
• Working fluency with PTP and hardware timestamping; comfortable reasoning about clock distribution and time accuracy on the wire.
• Solid grasp of firewall architecture, configuration, and troubleshooting.
• Strong network design instincts — you know when to optimize for latency, when for capacity, when for redundancy, and how to make those trade-offs explicit and defensible.
• Fast, structured troubleshooting under pressure. Fluent with packet capture (PCAP), sFlow / streaming telemetry, and capture appliances (Corvil-style); able to reason from layer-1 first principles.
• Network automation experience (Python, Ansible, or equivalent) and the appetite to design and build the next generation — including source-of-truth tooling (NetBox or similar) and CI for network configuration.
• Working knowledge of the network-adjacent hardware stack: fiber, transceivers (SFP/QSFP), DWDM, muxes, and layer-1 switching.

Nice to Have

• Experience operating in a low-latency trading or financial-market-connectivity environment.
• Track record of evolving an existing automation platform — not just consuming one.
• Experience integrating AWS or Azure networking into a hybrid environment.
• Exposure to microwave / wireless low-latency links.
• Industry certifications (CCNP, CCIE, JNCIE, or equivalent) appreciated, not required.
