Original job description

Clario, part of Thermo Fisher Scientific is seeking a Lead Mobile Application Engineer (.NET MAUI / Xamarin) to provide technical leadership in the design, development, and evolution of 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 lead the development of robust, scalable mobile applications using C#, MVVM architecture, and modern cross‑platform frameworks such as .NET MAUI, building on Xamarin‑based implementations where applicable. You will own key architectural decisions across the mobile platform, guide technical standards and best practices, and act as a technical reference point for mobile engineering within the R&D organisation.

What You’ll Be Doing

Define and own the architecture for cross-platform mobile applications using .NET MAUI, ensuring scalability, maintainability, and alignment with mobile engineering best practices.
Lead the development of core mobile application features using C#, .NET, and XAML, remaining hands-on with complex, performance-critical, and platform-specific components.
Drive the migration and modernization of legacy Xamarin.Forms applications to .NET MAUI, establishing standards, reusable components, and modernization strategies.
Collaborate with UX/UI teams to implement responsive, accessible, and high-performance user interfaces optimized for Android and iOS platforms.
Oversee integration with RESTful APIs, third-party SDKs, secure local data storage solutions, and offline synchronization mechanisms.
Establish and enforce coding standards, perform architecture and code reviews, and ensure application security, performance optimization, and stability.
Own the end-to-end mobile application lifecycle, including CI/CD pipelines, build automation, versioning, signing, and deployment to the Apple App Store and Google Play Store.
Mentor and guide senior and junior engineers, supporting technical decision-making and fostering a culture of engineering excellence and continuous improvement.
Act as a key technical partner to product owners, backend teams, QA, and other stakeholders, translating business requirements into robust technical solutions.

What We Look For

Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience
7+ years of professional software development experience
Hands-on experience with .NET MAUI or advanced experience with Xamarin.Forms, including proven migration expertise
Strong proficiency in C#, .NET, and XAML
Deep understanding of MVVM, clean architecture principles, and modern mobile design patterns
Proven experience delivering production-grade Android and iOS applications
Strong knowledge of mobile application lifecycles, threading, and platform-specific behaviors
Experience integrating RESTful APIs, third-party services, and secure local data storage solutions
Familiarity with CI/CD pipelines and modern DevOps practices for mobile application delivery
Demonstrated leadership skills, with the ability to mentor engineers and guide architectural decisions
Strong communication skills and the ability to collaborate effectively with technical and non-technical stakeholders

At Clario, our purpose is to transform lives by unlocking better evidence. It’s a cause that unites and inspires us. It’s why we come to work - and how we empower our people to make a positive impact every day. Whether you're advancing clinical science, building innovative technology, or supporting our global teams, your work helps bring life-changing therapies to patients faster.
