Int/Sr Network Infrastructure Engineer to Support Enterprise Network Infrastructure for Automotive Manufacturing Client
Location: Cambridge, ON (primarily on-site, up to 1 day/week remote when possible)

Type: Contract - Immediate Start, Annual renewals in April based on performance

Industry: Automotive Manufacturing

About the Role
Our client, a leading Canadian automotive manufacturer, is looking for a Network Infrastructure Engineer to join their Information Systems Engineering team. This is a hands-on enterprise networking role supporting manufacturing, corporate, and data center operations across two production facilities.

You'll be responsible for the design, implementation, support, troubleshooting, and continuous improvement of the organization's network infrastructure in a production-critical environment where uptime directly impacts manufacturing operations. The team values people who can work independently, think on their feet, document their work clearly, and take ownership from problem identification through to resolution.

This role has a strong track record of long-term contractor retention - several contractors have been with the team for 5+ years - and annual renewal decisions are based on performance.

What You'll Do

Design, implement, and support enterprise Cisco network infrastructure across switching, routing, wireless, and security layers

Administer and maintain Cisco Catalyst Layer 2/3 switching environments including STP, HSRP/VRRP, EtherChannel, and VLAN design

Configure and troubleshoot routing protocols and WAN connectivity

Administer Palo Alto firewall policies, rules, and security segmentation

Support Cisco Wireless infrastructure and manage Cisco Catalyst Center (formerly DNA Center)

Manage network access control via Cisco ISE

Monitor network health and respond to incidents using SolarWinds and other network monitoring tools

Manage DNS/DHCP services and fiber infrastructure across both facilities

Lead or support network projects end to end - from design and implementation through documentation and handover

Participate in after-hours and weekend maintenance windows and on-call support rotation

Contribute to continuous improvement initiatives and maintain clear, accurate technical documentation

What We're Looking For
Must-Haves

Robust hands-on experience with Cisco Catalyst Layer 2/3 switching (Catalyst 9300 series preferred)

Solid routing fundamentals - OSPF, BGP, static routing, route redistribution, STP, HSRP/VRRP, VLAN design

Experience with network security and segmentation - ACLs, VRFs, IPSec VPN tunnels, NAC





Palo Alto firewall administration experience

DNS/DHCP management in enterprise environments

Strong troubleshooting and root cause analysis skills - comfortable working in production environments where issues need to be resolved quickly and correctly

Clear documentation and technical communication skills

Change management experience - comfortable working within formal CAB/ITIL processes

Self-directed - able to manage workload independently with minimal oversight

Nice-to-Have

Cisco ISE (Identity Services Engine)

Cisco Wireless (Wi-Fi 6/7)

Cisco Nexus platform experience (data center switching)

Primarily on-site in Cambridge, ON with up to 1 day/week remote

Woodstock facility rotation approximately 1-2 days per month for on-site network support

After-hours and weekend work required for maintenance windows and on-call incident support
