More about the role & team
This is a senior, hands-on networking opportunity where you’ll own enterprise infrastructure end-to-end — from initial design through implementation and into steady-state operations. Working closely with infrastructure and business stakeholders, you’ll deliver complex network solutions while ensuring they are scalable, secure, and fully embedded into ongoing support. This role exists to strengthen internal expertise and reduce reliance on external vendors, placing you at the center of critical infrastructure transformation initiatives.
You’ll operate as a true Subject Matter Expert and technical escalation point, leading troubleshooting, optimizing performance, and driving continuous improvement across the network estate. Beyond delivery, you’ll play a key role in enabling the wider team through knowledge transfer, documentation, and best practices. This role suits a senior network engineer who enjoys both building and owning solutions, and who thrives in environments where they can influence standards, drive change, and work across large-scale, multi-site infrastructure.
Why should you apply?
- Own the full network lifecycle — from design through to operations, not just delivery
- Step into a true SME role with visibility and influence across infrastructure decisions
- Work hands-on with modern Cisco technologies, including SD-WAN transformation
- Drive real impact by building internal capability and reducing vendor reliance
- Gain exposure to enterprise-scale, multi-site environments and cross-functional initiatives
Based in a major tech hub (e.g., Toronto, US, or Ireland), this is an attractive opportunity for candidates looking to work on modern Cisco technologies and SD-WAN transformation within an enterprise-scale environment. You’ll gain exposure to cross-functional initiatives, cloud-integrated infrastructure, and projects with real business impact—ideal for those ready to step into a visible, high-impact engineering role with long-term growth
