As Principal Engineer, Integration Design, you'll own NABServ and drive its transformation into a secure, compliant software foundry that enables teams to build and release microservices at scale.
* Work in a collaborative environment with highly talented and motivated colleagues that are passionate about winning together
* Apply critical thinking and innovation as a trusted advisor to ensure production stability.
* Lead the future of platform engineering at NAB
Our people are customer obsessed. They prioritise the needs and satisfaction of the customer above all else. Our mindset fosters innovation and creates strong, lasting customer relationships as we strive to be the most customer centric company in Australia and New Zealand.
In this Principle Engineer, Integration Design role, you will join our Integration and Tech Governance team owning it and winning together.
Responsibilities
* Own and evolve NABServ (platform roadmap and technical direction): Set a clear technical roadmap for the platform: developer experience, standard patterns, runtime currency, operational readiness. Establish effective contribution and decision mechanisms so the platform scales with demand (platform product mindset).
* Rationalize microservices and reduce duplication: Establish a practical method to identify duplicated capabilities and overlapping services. Drive service boundary rationalization and consolidation outcomes with domain teams, improving cohesion and reducing unnecessary network calls.
* Move governance into code (automation-first controls): Convert key standards and guardrails into automated checks within delivery pipelines, reducing reliance on manual governance. Promote "secure defaults" and enforceable controls as part of the standard build-and-release path.
* Enable event‐driven integration patterns where they improve resilience: Drive consistent event‐driven approaches to reduce tight synchronous coupling and improve system resilience.
* Lead data‐driven executive conversations: Establish clear baselines, targets, and progress measures for simplification and platform adoption. Present options, trade‐offs, and sequence to senior stakeholders; drive decisions to completion.
Qualifications
* Microservices architecture expertise: service boundaries, decomposition, right sizing, and operational trade‐offs.
* Strong Java and Spring Boot engineering experience in production environments (design, build, operate).
* Strong NodeJS engineering experience for production services.
* Strong build and delivery engineering: Gradle; experience with modern build optimisation approaches (Bazel exposure desirable).
* Cloud‐native delivery experience (containers, Kubernetes‐based runtime, CI/CD, release safety practices).
* Experience influencing senior technology stakeholders (CIO/GM level).
* Strong platform/product mindset builds reusable capabilities and sets guardrails that scale.
* Strong communication: can explain complex topics simply and drive alignment across teams.
