We're a purpose-led organisation with a proud history and a clear vision: to support Kiwis in getting one step ahead. Our work is guided by strong values - care, courage and curiosity - and brought to life by a diverse team of people who genuinely care about making a difference.

Mō te tūranga | About the role

As a Senior Software Engineer - Platform Engineer, you'll strengthen the reliability, security and operational resilience of some of ASB's most important customer-facing platforms. You'll combine deep infrastructure expertise with modern engineering practices to help build a more resilient, automated and scalable technology environment.

You'll join the SIS Squad within Customer Tribe, a platform engineering and Site Reliability Engineering team responsible for infrastructure, server platforms and operational excellence across the Tribe. This role works across multiple squads and services rather than a single application, helping uplift platform reliability, automation and operational capability across critical customer systems.

Working across a predominantly on-premises environment with growing cloud adoption, you'll support and improve Windows and Linux platforms while driving greater automation, observability and operational excellence. The role combines hands-on engineering with strategic thinking, giving you the opportunity to improve reliability today and help shape a stronger operating model for the future.

In This Role, You Will

• Maintain and optimise critical Windows and Linux server environments.
• Drive vulnerability remediation, platform security improvements and more effective patching through automation.
• Support reliable, secure and highly available services across Customer Tribe.
• Design and implement operational tooling, monitoring, alerting and observability solutions.
• Build and maintain CI/CD pipelines supporting platform and infrastructure delivery.
• Identify operational risks and implement preventative controls.
• Participate in incident response, problem management and post-incident reviews.
• Develop automation that improves platform management, security and operational efficiency.
• Partner with engineering teams to promote Site Reliability Engineering principles and practices.
• Create and maintain technical documentation, runbooks and operational procedures.
• Influence platform strategy and recommend improvements that enhance reliability and reduce operational effort.
• Collaborate across squads to solve complex platform and infrastructure challenges.
• Participate in on-call support when required.
