Description:

We are seeking a talented and experienced Senior Software Engineer specializing in .NET MAUI to join our client's cross-platform mobile development team. In this role, you will design, build, and maintain high-performance applications that run seamlessly on Android, iOS, from a single shared codebase. You will work closely with product managers, UX designers, and backend engineers to deliver polished, production-grade experiences to our users.

As a senior member of the team, you will also mentor junior developers, contribute to architectural decisions, and champion engineering best practices across the organization.

Responsibilities:

  • Design, develop, and maintain cross-platform applications using .NET MAUI targeting Android, iOS.
  • Architect scalable, maintainable solutions following MVVM, Clean Architecture, and SOLID principles.
  • Implement native platform integrations and custom renderers/handlers where platform-specific behaviour is required.
  • Proficiency with platform-specific APIs on Android (Java/Kotlin interop) and iOS (Swift/Obj-C interop).
  • Collaborate with UX/UI designers to translate wireframes and mockups into responsive, accessible user interfaces.
  • Integrate RESTful APIs and backend services with robust error handling.
  • Write comprehensive unit tests, integration tests, and UI tests using xUnit, NUnit, or MSTest along 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 initiatives.
  • 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.

Requirements:

  • 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/Obj-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 branch 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 are a plus.
