Level 2 VoIP Support Engineer

Salary: $70,000 – $85,000 per year

About the role

You are the person who takes a voice or connectivity fault and owns it until it is fixed and proven fixed. Twelve months in, success looks like this: faults raised overnight UK time are resolved or properly progressed before the UK team starts their day, your fault records are clean enough that nobody needs to ask you what happened, and the recurring problems you spotted have turned into permanent fixes. Progressing projects overnight so the UK team can signoff with customers quicker.

Key responsibilities

• Own customer faults across hosted voice, SIP trunks, broadband and access circuits, from first contact to confirmed restoration

• Diagnose using packet captures, SIP traces, RTP flow analysis and router interfaces

• Resolve call quality, call flow, registration, routing and vendor interoperability issues

• Progress faults directly with carriers and platform providers, and hold them to account

• Prove the fix with line tests, QoS checks and end-to-end test calls

• Work alerting and ticket queues by service impact and SLA

• Keep accurate, structured fault records that meet regulated standards

• Feed repeat issues into root cause work with the UK engineering and provisioning teams

• Working knowledge of IP networking: addressing, routing, NAT, DNS and QoS

• Experience configuring business routers and customer premises equipment

• Experience working tickets to SLAs in a busy queue, with clear written fault notes

• Clear spoken and written English for dealing with UK customers and carriers

• Legally entitled to work in New Zealand
