Senior Platform Engineer (Software Consultant) - Customer Tribe

Senior Platform Engineer (Software Consultant)

Modern banking relies on technology that is secure, reliable and always available. Behind every customer interaction is a complex ecosystem of platforms, services and infrastructure that must operate seamlessly at scale.

As a Senior Platform Engineer, you'll play a critical role in strengthening 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 that supports millions of customer interactions every year.

You'll join ASB's Customer Tribe at an exciting time as we continue to evolve our platform capabilities, centralise Site Reliability Engineering (SRE) expertise, and invest in modern engineering practices that improve reliability, reduce operational risk and enable faster delivery.

About The Team

Customer Tribe is responsible for many of the digital platforms and services that support how customers interact with ASB every day. From the technology foundations that power customer experiences through to the platforms that enable secure and reliable banking services, the Tribe plays a critical role in delivering great outcomes for customers while maintaining operational resilience at scale.

You'll join the SIS Squad, a platform engineering and Site Reliability Engineering team responsible for infrastructure, server platforms and operational excellence across the Tribe. The squad is focused on building stronger platform capability, improving reliability, reducing operational risk and enabling engineering teams to deliver services more efficiently through automation and modern engineering practices.

Unlike many engineering roles, this position isn't tied to a single application or product area. You'll work across multiple squads and services, helping uplift platform reliability, infrastructure capability, automation and operational excellence across a broad range of critical customer systems.

About The Role

This is a senior technical role that combines platform engineering, infrastructure operations and Site Reliability Engineering.

You'll work across a predominantly on-premises environment with growing cloud adoption, helping teams manage and improve critical Windows and Linux platforms while driving greater automation, observability and operational excellence.

Initially, you'll partner closely with existing platform and reliability engineers to understand the current environment, support platform operations, vulnerability management and patching activities, and identify opportunities for improvement. Over time, you'll help shape the future state by reducing manual effort, improving operational processes, strengthening reliability practices and introducing automation that allows teams to operate more efficiently.

This role offers a unique balance of hands-on engineering and strategic thinking. You'll be expected to roll up your sleeves when needed while also stepping back to identify broader opportunities, influence direction and drive meaningful platform improvements across the Tribe.

Success in this role means improving reliability today while helping design a better operating model for tomorrow.

Key Responsibilities

• Maintain and optimise critical Windows and Linux server environments
• Drive vulnerability remediation and platform security improvements
• Improve patching processes through automation and engineering-led solutions
• Support reliable, secure and highly available services across Customer Tribe
• Design and implement operational tooling, monitoring and alerting solutions
• Build and maintain CI/CD pipelines supporting platform and infrastructure delivery
• Improve observability through dashboards, metrics, logging and alerting
• 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

About You

You're an experienced platform, infrastructure or Site Reliability Engineer who enjoys solving complex technical problems and improving the way technology operates.

You're equally comfortable supporting critical production systems, automating repetitive work, engineering more resilient solutions or helping teams adopt better operational practices. You enjoy understanding how things work beneath the surface and are motivated by finding smarter, more scalable ways to solve problems.

You'll bring strong technical depth, a pragmatic approach to problem solving and the ability to balance operational excellence with longer-term strategic thinking. Most importantly, you'll enjoy working collaboratively and influencing positive change across a complex technology environment.
