Senior Software Developer (Mobile Applications)

About the role

The Senior Software Developer is responsible for leading the design, development, and maintenance of our mobile applications across iOS and Android. You will build cross-platform features using .NET MAUI while working natively where platform-specific capability is required, own the quality and performance of the mobile experience in customers’ hands, and help shape our mobile architecture and release practices.

Responsibilities

• Lead the design and development of cross-platform mobile applications using .NET MAUI and C# for both iOS and Android, building native functionality in Swift/SwiftUI or Kotlin/Java where platform-specific capability, performance, or API access requires it.
• Architect scalable, robust, and maintainable mobile applications that meet performance, reliability, and security requirements, and write clean, efficient, well-documented code adhering to coding standards.
• Implement responsive, intuitive interfaces that follow platform design conventions and accessibility standards, including push notifications, deep linking, background execution, and device permission handling.
• Integrate mobile applications with backend REST APIs, implementing offline-first behavior, local persistence, and reliable data synchronization.
• Own the mobile release process end to end (build pipelines, code signing, provisioning profiles, submissions to App Store Connect and Google Play Console, and beta distribution and staged rollouts via TestFlight and Play Console release tracks), working with our DevOps team to ensure all processes are automated and repeatable.
• Instrument applications for crash reporting, performance monitoring, and usage analytics; diagnose and resolve platform-specific issues including memory pressure, threading and concurrency defects, battery consumption, and device fragmentation.
• Conduct comprehensive testing, debugging, and code reviews; collaborate with Quality Assurance to ensure software quality across the supported device matrix, and participate in incident response and root cause analysis for mobile-related issues.
• Provide technical leadership and mentorship to the development team while collaborating with product, architecture, and scrum teams to scope work, provide accurate estimates, translate business needs into technical solutions, document architecture and release procedures, demo functionality during Sprint Review, and stay current on emerging mobile technologies, platform releases, and store policy changes.

Qualifications

• Bachelor's degree in Computer Science or a related field. (Equivalent professional experience will be considered.)
• 5+ years of professional software development experience, with significant time focused on mobile application development.
• Hands-on experience building and shipping applications with .NET MAUI (or Xamarin.Forms with demonstrated MAUI migration experience) using C# and .NET, plus native mobile development experience in at least one of iOS using Swift/SwiftUI or Android using Kotlin/Java.
• Strong understanding of mobile application architecture and patterns such as MVVM, including state management and dependency injection, with experience integrating mobile applications with REST APIs and JSON and implementing local data persistence and offline synchronization using SQLite, Core Data, Room, or similar.
• Experience with the mobile app store release process (including code signing, provisioning profiles, App Store Connect, and Google Play Console) along with proficiency in mobile debugging and profiling tools such as Xcode Instruments or Android Studio Profiler and version control systems, preferably Git and GitHub.
• Proven ability to lead technical initiatives, mentor junior developers, and drive project success, with excellent problem-solving, communication, and collaboration skills, attention to detail and commitment to delivering high-quality software within agreed-upon timelines, and availability for occasional after-hours work or scheduled on-call hours.
