Purpose of Role

The Principal Engineer – Technology Standards & Patterns is responsible for defining, evolving and enabling the adoption of technology standards, reusable design patterns and implementation frameworks across PBWM. The role bridges Architecture and Engineering, translating strategic technology direction into practical, consumable standards, reference implementations and engineering guardrails that can be adopted consistently across business domains, platforms and engineering teams. Operating across PBWM, the Principal Engineer drives simplification, standardisation and reuse to improve technology consistency, reduce duplication and accelerate adoption of proven implementation approaches. The role focuses on establishing scalable technology foundations and common patterns that enable teams to deliver secure, resilient and maintainable solutions aligned to enterprise technology strategy.

Key Accountabilities

  • Technology Standards & Patterns: Define, maintain and evolve technology standards, design patterns and implementation guardrails across PBWM. Establish common integration models, API standards, event-driven patterns, resilience approaches and reusable implementation frameworks. Drive standardisation of common technology approaches to reduce duplication, improve interoperability and simplify solution design.
  • Architecture Enablement: Translate architecture principles and strategic technology direction into practical implementation guidance. Create reusable reference implementations, implementation playbooks and technology blueprints. Partner with engineering teams and architects to ensure standards remain practical, scalable and grounded in delivery realities.
  • Cross-PBWM Technical Leadership: Act as the senior technical authority for technology standards, reusable patterns and common implementation approaches. Partner with Architects and Engineering Leaders to align standards with strategic technology objectives. Collaborate with Platform Engineering, Security and Risk teams to embed controls, resilience requirements and governance expectations.
  • Technology Governance & Assurance: Promote adoption of approved standards, patterns and reusable implementation models. Identify fragmented approaches, duplicated implementations and inconsistent technology decisions. Ensure standards and patterns support security, resilience, scalability and regulatory requirements.
  • Continuous Evolution: Continuously assess emerging technologies, industry standards and engineering practices to evolve PBWM technology standards. Drive improvements to reusable capabilities and promote a culture of simplification, reuse and standardisation.
