Senior Android Developer

Senior Mobile Developer (Android)
Hawk-Eye Innovations

Salary: 58,810 - 80,190
Location: Hybrid - 2 days per week in the office (Basingstoke, London, or Bristol - whichever is nearest)

When Hawk-Eye was first used in 2001, it employed state-of-the-art camera and computer technologies for the time. Cameras ran at just 480x120 resolution, and the PCs processing that data were significantly slower than today's mobile phones.

Since then, Hawk-Eye has continuously evolved alongside technology, always pushing to deliver the very best solutions for elite sport. Today, Hawk-Eye systems are trusted at Wimbledon, Lord's, and across the Premier League.

Now, with the full support of Sony, Hawk-Eye is making a major push to bring this level of insight and innovation to the lower tiers of sport - and mobile devices are a key part of making that happen.

While Hawk-Eye has deep expertise in computer vision, tracking, and sports technology, we have limited experience building on mobile platforms. This role exists to bring that expertise in-house, blending mobile development knowledge with Hawk-Eye's core engineering strengths to create new, scalable solutions that can be used far beyond elite venues.

This is a permanent opportunity offering long-term growth, learning, and the chance to help shape the future of sport.

You'll be working on a production in-house Android application used by Hawk-Eye's tracking and development teams.

Key areas include:

• Enhancing and modernising an existing Android application

• Improving performance, stability, and user experience

• Working directly with mobile camera pipelines using the Android Camera 2 API

• Integrating and running machine learning models on-device to support:

• Supporting hands-on testing in live sports environments

• Collaborating closely with Tracking and Computer Vision teams to ensure clean system integration

• Lead best practices for Android mobile development

• Design, develop, and maintain high-quality Kotlin-based Android applications

• Own complex features from design through to delivery

• Work closely with developers across Tracking, Tooling, and Computer Vision

• Support testing, debugging, and deployment of new features

• Participate in technical discussions and code reviews

• Contribute pragmatically in an agile, sprint-based environment

Essential:

• Strong, hands-on experience in Android development using Kotlin

• Deep understanding of Android application architecture, lifecycle, and threading

• Proven experience working with the Camera 2 API in production

• Experience building high-performance, real-time mobile applications primarily using Kotlin

• Solid understanding of software design principles and clean code practices
