Mobile Solutions Architect - Flutter

What success looks like in this role:

Were looking for a seasoned Mobile Solutions Architect to lead the design and delivery of cross-platform mobile applicationsprimarily using Flutterfor enterprise environments. You will own end-to-end solution architecture, including mobile app design, API and backend integration, security and compliance, CI/CD, and governance. This role requires close collaboration with UK-based stakeholders and India development teams in an onshore/offshore model.

• Define and drive cross-platform mobile architecture, optimizing for scalability, performance, and maintainability.
• Lead Flutter technical strategy, patterns, and codebase organization (e.g., layered architecture, modularization).
• Select and enforce state management patterns (e.g., BLoC/Cubit, Provider, Riverpod, GetX) aligned with app complexity, testability, and performance best practices.
• Guide decisions on navigation, dependency injection, app lifecycle, theming, and localization.
• Architect and review RESTful service design, including resource modeling, pagination, error handling, and versioning.
• Ensure secure communication via TLS, certificate pinning, OAuth2/OIDC, and token lifecycle management.
• Design robust offline capability using local storage and databases (e.g., SQLite, Hive, ObjectBox), sync strategies, and conflict resolution.
• Partner with backend teams to define API contracts, performance SLAs, and observability (logging, metrics, tracing).
• Embed mobile security best practices: secure key storage (e.g., Keychain/Keystore), secrets management, jailbreak/root detection, secure logging, and runtime protections.

• Run secure SDLC activities: threat modeling, static/dynamic analysis, dependency auditing, and remediation.

You will be successful in this role if you have:

• 7-12 years in mobile development/architecture, with at least 3 years hands-on in Flutter and cross-platform architecture.
• Strong knowledge of state management (BLoC, Provider, Riverpod, etc.) and app architecture patterns (MVVM, Clean Architecture).
• Proven experience designing RESTful APIs and integrating secure mobile clients with backend services.
• Expertise in mobile security, secure storage, compliance frameworks (GDPR/ISO 27001), and secure communication practices.
• Hands-on with CI/CD for mobile, automated testing, and MDM/MAM integration (e.g., Microsoft Intune).
• Experience producing architecture diagrams, data flows, and integration documentation.
• Background in coding standards, scalability, and operational support of production mobile apps.
• Track record of successful onshore/offshore delivery (UK/India), stakeholder management, and agile practices.
