• Adapt and implement the design system for mobile platforms, working closely with the web architect

• Drive mobile performance — frame rates, battery, memory, startup time

• Make sure apps work well across devices, OS versions, and screen sizes

• Push accessibility standards on mobile platforms

• Mentor engineers and help grow mobile capability

• Oversee code reviews and provide hands-on technical input

• Keep architectural documentation clear and up to date

• Champion mobile-first thinking and respect native platform conventions

• Explain architectural decisions clearly to senior stakeholders

Expected Outcomes

• Mobile architectures that scale and don't create maintenance headaches

• Measurable improvement in mobile performance

• Design system used consistently across mobile platforms

Cross Functional Design Leadership

• Run workshops with product, design, and engineering to shape solutions

• Lead architectural trade-off discussions for mobile

• Step in during high-impact incidents or complex changes

• Help teams break down big technical and UX challenges into manageable pieces

Communication and Influence

• Use diagrams, models, and written artefacts to build shared understanding

• Influence product and engineering direction through sound reasoning

• Build strong working relationships across the organisation

Cross-Discipline Architectural Knowledge

• Domain-driven design principles

• Enterprise integration patterns

• Data architecture fundamentals

• Security basics and secure-by-design thinking

• DevOps and platform engineering practices

• Defining and assessing non-functional requirements

• Evaluating build vs buy and third-party tech

• Balancing performance, cost, resilience, and maintainability

Working with the Architecture Practice

• Contribute to shared standards, principles, and reusable patterns

• Take part in architecture forums, reviews, and governance
