Network Engineering Lead Kitchener, ON

Overview

Were hiring a Network Engineering Lead to own the design evolution and day-to-day operation of a multi-business production network.

This is an Individual Contributor role with tech-lead authority. Youll set technical direction mentor a senior engineer reporting to you and stay deeply hands-on with the gear. Youll 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.

Responsibilities

• 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.

• Share a 24/7 on-call rotation with your direct report. Routine known-solution incidents are handled by support staff.

Qualifications

• 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.
