Senior Android Engineer

This role owns the Android application for a new generation of tracking services for elite and semi-professional sport, from architecture and implementation through to release and ongoing reliability. It sits within a small, cross-functional engineering team building a new product, with a high degree of autonomy and AI-augmented development. The application captures data, coordinates devices, manages sessions and transfers information back to the wider system, and must work reliably in uncontrolled real-world conditions.

• Lead the design, architecture and implementation of a production-ready Android application, taking responsibility for quality, maintainability and performance.
• Develop and maintain the camera and media capture layer, including camera configuration, session management, recording and local storage.
• Build 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.
• Design robust data and media transfer with prioritisation, queuing, retries and partial-failure handling for unreliable networks.
• Integrate C++ computer vision components through the Android NDK and JNI, owning the Android application functionality and integration around them.
• Manage releases across environments, including Google Play submissions, internal testing tracks, remote configuration and release signing.
• Implement crash reporting, diagnostics and observability so issues can be understood and resolved without someone needing to be physically present.
• Account for battery consumption, thermal behaviour, background execution restrictions, permissions and differences across Android versions and device types.
• Collaborate closely with backend, design and computer vision engineers, managing dependencies and ensuring the application integrates effectively with the wider system.
• Maintain high engineering standards by writing testable, maintainable code, contribute to planning, estimation and task breakdown, identify risks and dependencies early, and use AI-assisted and delegated development tools within security and intellectual property guidelines.

• At least 4 years of mobile application development experience, including substantial delivery of native Android applications using Kotlin.
• A portfolio of applications shipped and available on Google Play.
• Experience taking applications through the full development lifecycle, from project creation and architecture to release signing and store approval.
• A degree in a software-related technical discipline, or equivalent practical experience.
• A willingness to learn new technologies, tools and platforms.
• Expert-level knowledge of native Android development using Kotlin.
• Expert-level knowledge of device-to-device communication and data serialisation, including technologies such as Wi-Fi Direct and Protocol Buffers.
• Expert-level knowledge of mobile camera and media systems, including capture pipelines, codecs and local storage management.
• Expert-level knowledge of building resilient applications for unreliable networks, including background transfers, queuing, retries and partial-failure handling.
• Comfortable with mobile CI/CD and automated release pipelines.
• Comfortable with writing unit and integration tests.
• Comfortable with Git, code management and code review practices.
• Comfortable with task and ticket management tools such as Jira.
• Comfortable with mobile application architecture and design.
• Comfortable with Android device lifecycle constraints, including thermal behaviour, battery usage, background execution limits, permissions and differences across OS versions and device tiers.

• Real-time and latency-sensitive data delivery.
• Integrating native computer vision or machine learning components into an Android application.
• Coordinating multiple devices as part of a single system.
• Kotlin Multiplatform and its potential as a future route to iOS.

• Hybrid model with 2 days per week in the office.

• Annual leave according to local labour law.
• Flexible working: hybrid model with 2 days in the office per week.
• Access to sporting events and tickets.
• Sony Group Company discounts.
• Cafeteria options (SZÉP Card, Nursery & Kindergarten contributions, Annual MOL Bubi Pass).
• Private medical insurance.
• Life and accident insurance.
• MindentMent Dental Clinic discounts.
• Seniority awards.
• Employee Assistance Program.
