Job description

Based in York Region, telMAX is a private equity-backed all fibre digital infrastructure platform that provides a 21st century alternative to traditional telecom networks. Recognized for four consecutive years as Canada’s Fastest ISP with an industry‑leading net promoter score of over fifty, telMAX is continuing its rapid growth plan to bring its all‑fibres network to residential and business customers across Southern Ontario.

Your Position & How You Will Contribute:

Reporting to the Director, Network and Security, the Core Network Engineer is the hands‑on owner of our core: routing, the QFX/MX/ACX fabric, and the IPAM/DHCP/DNS services everything else depends on. This is a senior individual‑contributor role on a small, capable team — you lead through the work, not through direct reports.

This role is built for someone who is production‑minded and thrives with direct ownership. You'll be hands‑on with the config, close to the infrastructure, and able to learn our as‑built network quickly and start making real improvements within your first three months. We'll give you the context, the access, and the air cover — we're looking for the experience and initiative to use them. As part of a growing company, you'll have real opportunities to expand your expertise and grow your career alongside the network.

Responsibilities & Key Duties:

Core Network Ownership

• Take ownership of the as‑deployed core: routing, the edge and the QFX/MX/ACX fabric.
• Add sites and capacity, optimize existing infrastructure, and keep resiliency ahead of growth.
• Bootstrap new QFX5120 deployments from a known‑good template and bring them online cleanly.

Routing and Fabric

• Own and Optimize E‑BGP toward transit and peers, and iBGP/EVPN‑XLAN inside the fabric.
• Maintain dual‑stack IPv4/IPv6 operations, including full tables, communities, and routing policy.
• Ensure routing configuration is well understood, documented and defensible.

Core Services

• Own IPAM, DHCP, and DNS as first‑class production services
• Ensure these services are stable, well documented, and managed with the same rigour as core routing infrastructure

Automation & Tooling

• Template, script, and automate repetitive work including: config generation and validation
• Build and maintain tools that keep a team efficient and consistent

Maintenance & Incident Response

• Plan and execute production maintenance with complete MOPs and rollback procedures
• Drive incident response with ownership and accountability, proactively before escalation is required
• Create and maintain accurate as‑builts and methods‑of‑procedures, and contribute to the accuracy of team documentation

What You Bring:

• Ownership Mindset: You take responsibility for the network end‑to‑end. When you see something wrong, you fix it or raise it — and you see open problems as yours until they're resolved.
• Full‑Stack Network Owner: You've worn multiple hats and liked it. You're comfortable owning routing, switching, and core services at once, and you don't need a large team or a long runway to be useful.
• Calm Under Fire: You're at your best when the network is at its worst. That steadiness is the standard we build the team around.
• Articulate: You translate technical reality to the business and business need back into the network. You document as you go so the next person inherits clarity, not archaeology.
• Collaborative and Team‑Oriented: Small team, large surface. You contribute frequently, ask good questions, presume positive intent, and bring others along. We win together — and that means showing up for your teammates as much as for the network.
• Detail‑Oriented and Resourceful: Strong attention to detail with a high level of accuracy. You are methodical in how you approach problems and thorough in how you close

Experience:

• Hands‑on experience operating a service‑provider or carrier‑grade IP network in Canada.
• Hands‑on eBGP and iBGP experience, dual‑stack, including EVPN‑VXLAN fabric operations.
• Practical ownership of IPAM, DHCP, and DNS in production (e.g., Infoblox, BIND, Kea, or equivalents).
• Scripting and config automation (Python, Ansible, or similar).
• Juniper (MX / ACX / QFX) and Junos fluency is required.
• JNCIS‑SP or higher is an asset. CCNP or higher is considered with Juniper transferability.
• Proven track record of delivering in a small‑team environment with direct ownership.

Education:

• Bachelors degree or diploma in Computer Science, Electrical/Electronic Engineering, Networking/Security, or equivalent in related fields.

Benefits:

• We are a growing, dynamic organization
• We offer a competitive variable compensation package
• Hybrid positions
• Benefits (Medical, Dental, and Vision)
• Health Spending Account (HSA)
• RRSP matching program
