Role Summary: Leads the architecture of mobile applications across Android and iOS using Flutter. Sets mobile standards, drives performance, and works with the web architect to keep design systems consistent across platforms. Needs broad architectural knowledge with deep mobile expertise.

Key Responsibilities

• Set the direction for mobile architecture

  
  

• Design mobile architectures that scale and are easy to maintain

  
  

• Define coding standards, patterns, and best practice for mobile

  
  

• Lead technical design reviews for mobile UI and UX decisions

  
  

• 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

  
  

• Better code quality through shared standards and practice

  
  

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

  
  

• Help shape architectural roadmaps and long-term plans

  
  

• Share what works so other teams can reuse it

  
  

• Stay aligned with the Senior Solution Architect - Web across front-end disciplines

  
  

Decision Making Authority

• The go-to authority on mobile architecture

  
  

• Owns how the design system is adapted for mobile

  
  

• Balances short-term delivery needs against long-term thinking
