Senior Mobile Engineer
ROLE PURPOSE
This role owns iiDENTIFii ’s mobile engineering output end-to-end. You are responsible for designing, building, testing, and shipping high-performance mobile applications — primarily on iOS, with Android and cross-platform experience advantageous — that meet the exacting quality, security, and performance standards of a biometric identity platform used by tier-1 financial institutions.
This is a hands-on engineering role operating at the intersection of product, design, and backend. You will work closely with product managers, backend developers, and QA teams across all stages of the development lifecycle — from requirements and architecture through to release and ongoing optimisation. You bring both technical depth and a high standard of craft: clean, maintainable code, user-driven ui, rigorous testing, and a genuine interest in getting the details right.
Operating in a security-sensitive, compliance-heavy domain, you are expected to bring sound judgement to architecture decisions, stay current with the evolving mobile landscape, and contribute to a culture of technical excellence across the engineering team.
ROLE TASKS & RESPONSIBILITIES
Application Development & Architecture
- Design and build advanced applications for iOS (essential) and Android/Cross-Platform (advantageous), ensuring responsiveness, performance, and a seamless user experience across all supported devices
- Own mobile features from concept through to implementation: scoping, architecture, build, test, and release
- Collaborate with cross-functional teams to define, refine, and implement new mobile features that align with product strategy and client needs
- Identify and implement performance improvements that meaningfully enhance application responsiveness and reliability in production
- Stay current with mobile trends, emerging technologies, and best practices across iOS, Android, and cross-platform frameworks — and bring relevant opportunities to the team proactively
Engineering Standards & Code Quality
- Write clean, maintainable, and efficient code in Swift and Objective-C (iOS — essential) and Java, Kotlin (Android — advantageous), and across cross-platform frameworks such as React Native or Flutter
- Apply SOLID principles and modern mobile architecture paradigms — including microservices and event-driven patterns — to produce code that scales and survives production
- Conduct thorough code reviews, providing constructive technical feedback and upholding engineering standards across the team
- Maintain clear and useful technical documentation covering architecture decisions, coding standards, and design rationale
- Optimise code for speed, scalability, and maintainability; identify and resolve technical debt proactively
Testing, Debugging & Quality Assurance
- Conduct thorough testing of applications to identify and resolve bugs and performance issues before they reach production
- Apply TDD/BDD best practices and maintain well-tested, reliable code as a non-negotiable standard
- Work with QA teams to design and implement automated testing strategies that reduce manual effort and increase release confidence
- Debug and resolve production issues promptly, conducting root cause analysis and sharing learnings with the broader team
UI/UX Implementation
- Use Claude Design to create attractive, intuitive, and consistent interfaces across all UI and UX flows
- Ensure mobile applications meet high-quality UI/UX standards and adhere to Apple and Android design principles throughout
- Translate design specifications into performant, pixel-accurate code that delivers a seamless end-user experience
DevOps, CI/CD & Deployment
- Collaborate with DevOps teams to ensure smooth deployment processes, robust CI/CD pipelines, and clean code integration
- Use version control systems (Git) with discipline: clear branching strategies, meaningful commit messages, and clean pull request hygiene
- Contribute to improving deplo
