Principal Software Engineer (Integration Platform Modernisation) at Commonwealth Bank in Perth Central

Job description

• Principal Software Engineer (Integration Platform Modernisation)
• Shape the target architecture for enterprise integration and communications platforms.
• Lead a significant AWS cloud-native modernisation across critical banking capabilities.
• Influence engineering standards, reusable patterns and technical decisions across multiple squads.
• Do Work That Matters
• As Principal Software Engineer in Bankwest Technology, you will provide strategic technical leadership across our enterprise integration and communications platforms. This is a significant modernisation opportunity. You will shape the transition towards AWS cloud-native architectures, defining target architecture, engineering standards and reusable capabilities while helping teams navigate complex re-platforming decisions.

Responsibilities

• Set the technical direction and target architecture for enterprise integration and communications capabilities.
• Shape modern patterns across APIs, event-driven architecture, messaging, streaming and asynchronous processing, with clear guidance on when each approach should be used.
• Lead the replatforming of critical capabilities to AWS using appropriate cloud-native, managed and serverless services.
• Establish reusable capabilities that reduce point-to-point integration, duplication and bespoke engineering.
• Define engineering standards across security, resilience, observability, scalability and developer experience.
• Create pragmatic migration and transition patterns that protect critical services while legacy platforms are progressively replaced.
• Partner with engineering teams, architects and other Principal Engineers to align solutions with the broader technology landscape.
• Remain technically hands-on enough to validate designs, explore new capabilities and solve complex engineering problems.

Requirements

• You are a strategic engineering leader who combines deep architecture capability with practical engineering judgement. You can establish a clear technical direction, influence across organisational boundaries and help teams turn complex modernisation goals into safe, achievable outcomes.
• Bring significant experience designing or modernising large-scale integration, distributed systems or enterprise platform capabilities.
• Have deep knowledge of AWS and cloud-native architecture, including managed and serverless services.
• Understand API design, event-driven architecture, enterprise messaging, streaming and asynchronous processing.
• Have led major platform modernisation or replatforming initiatives while maintaining service continuity.
• Can design for security, resilience, scalability, observability and operational excellence.
• Are comfortable working primarily across backend engineering and architecture.
• Can work effectively with .NET Core environments or bring strong experience in another modern language and an openness to working with .NET.
• Combine thought leadership and influencing skills with the technical depth to challenge designs and guide implementation.
