Ready to take your network career to the next level? We'd love to hear from you.

What You'll Be Doing

This is a hands-on Tier 3 role where no two days look the same. You'll be a trusted technical expert — solving complex faults, driving network improvements, and being the go-to engineer for a high-profile enterprise customer.

Day-to-day, you'll:

• Diagnose and resolve complex network incidents, keeping customers running within tight SLAs
• Lead problem resolution across the full lifecycle — from fault identification through to fix and follow-up
• Design and maintain network documentation, diagrams, and implementation plans to a high standard
• Support and deliver network upgrades, migrations, and new implementations
• Collaborate with cross-functional teams, vendors, and contractors to deliver secure, scalable solutions
• Contribute to automation and scripting initiatives to drive efficiency

The Setup

We know flexibility matters. This role offers a hybrid working arrangement:

• 1–2 days per week on-site at Auckland Airport Site.
• 2 days at our Spark office
• 1 day working from home

You'll be available across a 7am–7pm weekday window on a rostered basis, with occasional after-hours on-call support. In return, you'll be part of a supportive, highly skilled team working on enterprise infrastructure that genuinely matters.

What You'll Bring

Must-haves:

• 5+ years in network infrastructure, ideally within a telco, service provider, or large enterprise environment
• Strong hands-on experience with Arista (switching, WiFi, CloudVision, AGNI) and Cisco (ISE, DNA Center, routing & switching)
• Solid knowledge of BGP, OSPF, EIGRP, MPLS, and QoS
• Strong WiFi expertise and a deep understanding of hardware/software performance and scaling
• Excellent communication skills — you'll be customer-facing and need to translate technical complexity clearly
• A relevant qualification in networking or a related field

Bonus points for:

• Experience with Fortinet SD-WAN, Velocloud, Catalyst SD-WAN, or Aruba wireless/switching
• Scripting and automation skills — Python, Ansible, Terraform, or Jenkins
• Relevant certifications (CCNP, CCIE, Arista ACE, or similar)
