Application Architect - Mobile App

Introduction

We are looking for an experienced Application Architect to shape the architecture of our mobile app solution.

You will work across product and engineering teams on a large-scale, multi-brand customer application based on a hybrid architecture combining React Native, native iOS/Android capabilities, WebViews, App BFF and backend services.

Your key responsibility will be to define and evolve the overall architecture of the app solution, establish architectural principles and guardrails, and ensure that technical solutions remain scalable, secure, maintainable and consistent across brands and components.

Tasks

• Define and evolve the target architecture for the mobile app solution
• Define architectural principles, patterns and guardrails across React Native, native capabilities, WebViews, App BFF and integrations
• Define clear responsibilities and boundaries between app components and technology layers
• Own architectural decisions for major cross-component topics and integration patterns
• Define and govern architectural principles and non-functional requirements related to performance, stability, scalability, security, resilience, observability and maintainability
• Evaluate emerging AI use cases for the app and define the required architectural patterns, integrations and guardrails in collaboration with relevant architecture, security and engineering teams
• Review major technical designs and ensure alignment with the target architecture
• Collaborate closely with Solution Architects and Domain Architects to ensure alignment with broader platform, integration and enterprise architecture principles
• Coordinate architectural dependencies and interfaces between the app solution and surrounding domains
• Identify architectural risks, dependencies and technical debt and drive appropriate mitigation
• Ensure architectural consistency across multiple brands and product teams
• Support technology evaluations and architectural decisions for the evolution of the app platform
• Collaborate closely with Technical Leads, Product Owners, Developers, Security, Platform and backend engineering teams
