Clario is seeking a Senior Mobile Application Engineer (.NET MAUI / Xamarin) to help design, build, and evolve the Clario App—our core mobile platform used by patients and clinical research sites across global clinical trials. This platform plays a critical role in how patients engage with research, enabling reliable data collection, improving compliance, and supporting a high‑quality trial experience.

In this role, you will develop robust, scalable mobile applications using C#, MVVM architecture, and modern cross‑platform frameworks such as .NET MAUI, building on Xamarin‑based foundations where applicable. You will take ownership of mobile solution design, contribute to architectural decisions, and continuously raise standards for code quality, performance, and maintainability.

What You’ll Be Doing

• Design, develop, and maintain scalable cross-platform mobile and desktop applications using .NET MAUI, ensuring high performance, reliability, and maintainability.

• Lead the modernization and migration of existing Xamarin.Forms applications to .NET MAUI, applying clean architecture principles and MVVM patterns.

• Implement responsive, accessible, and high-quality user interfaces using XAML, with platform-specific optimizations for Android and iOS.

• Integrate mobile applications with RESTful APIs, third-party services, and platform SDKs, ensuring secure data handling and reliable offline functionality.

• Apply best practices for local data storage, including SQLite, synchronization strategies, and offline-first design patterns.

• Ensure software quality through code reviews, unit and integration testing, debugging, and adherence to established engineering standards.

• Manage the mobile application lifecycle, including build automation, CI/CD pipelines, versioning, signing, and deployment to the Apple App Store and Google Play Store.

• Collaborate closely with UX/UI designers, backend engineers, QA teams, and product stakeholders to deliver cohesive, user-focused solutions.

• Provide technical guidance and mentorship to junior engineers, contributing to a collaborative and high-performance engineering culture.

What We Look For

• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience

• 5+ years of professional experience in software or mobile application development

• Hands-on experience developing applications using .NET MAUI

• Strong proficiency in C#, .NET, and XAML

• Solid understanding of MVVM, dependency injection, and modern software design patterns

• Experience working with Xamarin.Forms and migrating applications to .NET MAUI

• Strong knowledge of mobile application lifecycles and platform-specific behaviors on Android and iOS

• Experience integrating RESTful APIs and working with JSON-based data exchanges

• Proficiency with Git and modern CI/CD pipelines

• Strong problem-solving skills, attention to detail, and ability to work independently on complex features

• Effective communication skills and the ability to collaborate with cross-functional teams
