ABOUT THE ROLE
We are looking for an experienced Senior Software Engineer to join a cross-platform mobile development team. In this role you will design, build, and maintain high-performance applications that run on Android and iOS from a single shared .NET MAUI codebase. You will work closely with product managers, UX designers, and backend engineers to deliver polished, production-grade experiences.
As a senior member of the team, you will also mentor junior developers, contribute to architectural decisions, and champion engineering best practices across the team.
KEY RESPONSIBILITIES
- Design, develop, and maintain cross-platform applications using .NET MAUI for Android and iOS.
- Architect scalable, maintainable solutions following MVVM, Clean Architecture, and SOLID principles.
- Implement native platform integrations and custom handlers where platform-specific behaviour is required.
- Collaborate with UX/UI designers to translate wireframes and mockups into responsive, accessible interfaces.
- Integrate RESTful APIs and backend services with robust error handling.
- Write comprehensive unit, integration, and UI tests using xUnit, NUnit, or MSTest together with Appium or similar frameworks.
- Optimise application performance, including startup time, memory usage, rendering, and battery consumption.
- Conduct code reviews, provide constructive feedback, and mentor junior and mid-level engineers.
- Participate in Agile ceremonies (sprint planning, stand-ups, retrospectives) and contribute to continuous improvement.
- Stay current with .NET MAUI releases, Xamarin migration paths, and the broader .NET ecosystem.
- Maintain CI/CD pipelines for automated building, testing, and deployment of mobile applications.
REQUIRED QUALIFICATIONS
- Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.
- 8+ years of professional software development experience with C# and the .NET ecosystem.
- 5+ years of hands-on experience with .NET MAUI or Xamarin.Forms, with demonstrated MAUI migration expertise.
- Proficiency with platform-specific APIs on Android (Java/Kotlin interop) and iOS (Swift/Objective-C interop).
- Experience consuming and integrating RESTful and/or GraphQL APIs.
- Solid knowledge of dependency injection, asynchronous programming (async/await), and reactive patterns.
- Familiarity with Git-based workflows, pull request culture, and branching strategies (GitFlow, trunk-based).
- Strong debugging, profiling, and performance-tuning skills across multiple target platforms.
- Excellent written and verbal communication skills.
PREFERRED QUALIFICATIONS
- Knowledge of platform-specific design systems (Material Design, Apple Human Interface Guidelines, Fluent Design).
- Hands-on experience with Azure DevOps, GitHub Actions, or App Center for CI/CD.
- Familiarity with SQLite, Realm, or other embedded databases for local data persistence.
- Experience with accessibility standards (WCAG) and building inclusive applications.
- Contributions to open-source .NET or MAUI community projects.
- Relevant Microsoft certifications.
