Job description
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)
Join Hawk-Eye Innovations as a Senior Mobile Developer (Android)
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.
