Ko tō tūranga – your role

As our IT Service Reliability & Operational Excellence Manager, you’ll be accountable for the reliability and performance of customer-facing and business-critical applications and platforms, while helping transform how we operate technology at One NZ.

This isn’t a traditional IT Operations role. You’ll lead Application Operations and Site Reliability Engineering, working across Architecture, Engineering, Security, Delivery and our strategic partners to protect today’s services and improve AI enabled SDLC with focus on how we engineer, assure, release and run them for the future.

You’ll help move us towards stronger service and value-stream ownership, shifting reliability left and using engineering, automation and AI to improve service outcomes.

You’ll inherit an important operation — and we expect you to make it better.

Ko tō mahi – what you’ll do

• Own the reliability, resilience and performance of live IT services, with a clear focus on customer and business outcomes.
• Lead Application Operations and SRE, building stronger service ownership, engineering accountability and continuous improvement.
• Drive AI, AIOps and automation to predict issues earlier, reduce operational toil and increase self-healing.
• Making sure operational issues don't simply get resolved — they get translated into engineering, testing, environment, release and platform improvements.
• Evolve the operating model from reactive, application-based support towards service and value-stream ownership.
• Connect what is happening in live production back into Quality, Release, NPE, Service Desk, Architecture and Engineering, so the organisation continuously learns and improves
• Strengthen observability and reliability engineering, using service health, SLIs and SLOs to improve decisions and outcomes.

• Transform strategic partner performance from ticket and SLA management towards automation, engineering improvement and shared service outcomes.
• Improve operational readiness, problem management and resilience so change lands safely and recurring failure is systematically engineered out.
• For us, operational excellence means moving from reactive support to a more proactive, automated and Agentic AI-led model — with fewer incidents, faster recovery, stronger ownership and better customer outcomes
