Senior Android Engineer

Senior Android Engineer Location: Hungary (UK candidates also considered) Contract: Permanent, full-time About us Hawk-Eye Innovations is at the forefront of sports technology, delivering officiating, tracking, broadcast and performance solutions across some of the world's biggest sports. As part of Sony Sports, we continue to push the boundaries of innovation, helping athletes, coaches, teams, broadcasters and governing bodies make better decisions through technology. Build technology that changes how sport is experienced What if athletes, coaches and teams could access the kind of tracking technology that has traditionally been out of reach? We’re building a new generation of tracking services for elite and semi-professional sport, creating products that bring powerful technology to the people who need it most. We’re looking for a Senior Android Engineer to take ownership of the mobile application at the heart of this experience. You’ll join a small, cross-functional engineering team building something new, with the opportunity to shape the architecture, influence technical decisions and see your work make a tangible difference. We work with a high degree of autonomy and embrace AI-augmented development to help us build and iterate at pace. The role You’ll own the Android application from architecture and implementation through to release and ongoing reliability. It’s the part of the product that athletes, coaches and teams interact with directly - the application that captures data, coordinates devices, manages sessions and transfers information back to the wider system. The challenge is making all of this work reliably in the real world. Our products are often set up and operated by users who have never used them before. They may be working on unreliable internet connections, managing multiple devices and operating in environments we cannot control. That means intuitive setup, clear feedback, resilient data transfer and graceful recovery from failures are fundamental to the product, not features to add later. You’ll work across the full Android stack, from camera capture and local storage to device-to-device communication, background processing and release management. You’ll also integrate native C++ components developed by our computer vision engineers, helping bring advanced tracking capabilities into a dependable mobile experience. This is a role for an engineer who enjoys owning complex problems end to end, making thoughtful architectural decisions and building software that works beyond the ideal conditions of a development environment. What you’ll be doing Own the Android application: Lead the design, architecture and implementation of a production-ready mobile application, taking responsibility for quality, maintainability and performance. Build the capture experience: Develop and maintain the camera and media capture layer, including camera configuration, session management, recording and local storage. Coordinate connected devices: Build the mechanisms that allow multiple devices and on-site edge units to operate as a single system, including communication, setup, synchronisation, shared state and recovery when connections fail. Make unreliable networks manageable: Design robust data and media transfer, with prioritisation, queuing, retries and partial-failure handling built into the application. Integrate native components: Connect C++ computer vision components through the Android NDK and JNI, owning the Android application functionality and integration around them. Own the release lifecycle: Manage releases across environments, including Google Play submissions, internal testing tracks, remote configuration and release signing. Build for reliability in the field: Implement crash reporting, diagnostics and observability so that issues can be understood and resolved without someone needing to be physically present. Design for real devices: Account for battery consumption, t
