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 deployment workflows, release automation, and build reliability across the mobile engineering function
  
  

Collaboration & Communication

• Work effectively in an agile environment with cross-functional teams — product, design, QA, backend, and DevOps — to deliver high-quality mobile experiences on time
• Communicate technical concepts clearly and confidently to both technical and non-technical stakeholders
• Provide technical guidance and knowledge-sharing to team members; contribute to a culture of continuous learning and mutual accountability
  
  

AI-Augmented Ways of Working

• Use AI tools as a standard, expected part of the role — a core professional competency, not optional
• Apply AI to accelerate code generation, debugging, documentation, test writing, and technical research
• Leverage AI to explore architectural options, evaluate trade-offs, and surface solutions faster than traditional approaches allow
• Model AI-augmented engineering practices for the broader team and contribute to embedding them into team norms
• Stay current with the evolving AI tooling landscape and proactively identify opportunities to increase productivity and output quality
  
  

Living the iiDENTIFii Culture

• Champion iiDENTIFii’s culture and values in every interaction — with teammates, product, and across the engineering function
• Foster a team environment defined by intellectual rigour, psychological safety, collaborative excellence, and a bias for action
• Actively contribute to iiDENTIFii’s mission: powering innovators in remote biometric digital authentication, globally
  

QUALIFICATIONS, EXPERIENCE & TECHNICAL SKILLS NEEDED 

Experience

• Proven experience as a mobile developer with strong iOS expertise (essential) and Android exposure advantageous, with a portfolio of shipped applications across one or both platforms
• Demonstrated experience building end-to-end mobile applications: from design and architecture through development, testing, deployment, and store release
• Experience working in agile, cross-functional teams alongside product, design, QA, backend, and DevOps
• Strong understanding of the full mobile software development lifecycle and production engineering discipline
• Experience contributing to code reviews, technical documentation, and best-practice engineering standards
• Exposure to performance optimisation, scalability challenges, and production support at scale
• Experience with CI/CD pipelines and automated testing practices
• Experience with cross-platform mobile solutions (React Native, Flutter) is advantageous
• Understanding of modern software architecture concepts such as microservices and event-driven systems

Technical Skills

• Languages: Proficiency in Swift and Objective-C (iOS — essential); Java and Kotlin (Android — advantageous)
• SDKs & IDEs: Strong experience with iOS SDK and Xcode (essential); Android SDK and Android Studio advantageous
• API Integration: Experience integrating mobile applications with RESTful APIs and backend services
• Architecture: Knowledge of mobile application architecture, lifecycle management, and state management
• UI/UX: Familiarity with UI/UX implementation aligned to Apple and Android design principles
• Version Control: Experience with Git/GitHub and disciplined source control practices
• Testing: Strong debugging, testing, and performance tuning skills; TDD/BDD exposure
• DevOps: Familiarity with CI/CD pipelines, DevOps practices, and release automation
• Performance: Knowledge of offline storage, threading, memory management, and performance optimisation
• Cross-Platform: Exposure to React Native, Flutter, cloud messaging, push notifications, and modern mobile trends

Education

• A degree in Computer Science, Software Engineering, or a related field; equivalent demonstrated experience is equally valid
