Front-End Developer - Realtime Sports Graphics & Web Rendering
About Us
Rezzil creates performance products for sport across VR, mobile, console and gaming, serving B2B, B2C and elite performance markets. Our products support training, analysis, fan engagement and immersive sports experiences across the sports industry.
Exar.live is our live game data ingest and transport platform, powering real-time analysis tools for VR, broadcast and performance environments. As we continue to grow, we are also expanding into new areas, including computer vision and AI-driven solutions.
We are Manchester based, with an office in London, and we will be opening US offices later this year as we continue to build our presence across the UK, US and global mobile markets.
The opportunity
We are looking for a Front-End Developer to help build the next generation of real-time sports visualisation and interactive rendering systems across our broadcast, consumer and performance products.
This role is focused on developing modern web-based front-end systems capable of rendering live sports data in real time. These systems will power everything from broadcast graphics and analysis tools through to immersive fan and athlete experiences.
You will play a key role in designing, developing and maintaining a shared rendering platform that can be integrated throughout Rezzil’s product ecosystem. Alongside this, you will contribute to the wider front-end development of our web applications, internal tooling and product interfaces.
