Machine Learning Engineer

About Us

Launched in 2021, Bolt6 is an Emmy award-winning start-up dedicated to improving the experience of sport for everyone. Our products help to improve fan engagement, officiating acceptance, and drive commercial performance for sports leagues and federations.

We use cutting-edge technology to do a variety of amazing things with cameras and other data sources (all in real-time on site or in the cloud), including:

• Tracking the 3D position of vehicles in elite motorsport (e.g. NASCAR)
• Ball and skeletal player tracking of athletes in a number of top level sports
• Electronic line calling in tennis and volleyball
• Providing the platform for sports federations to make critical officiating decisions using video and tracking data

We have a commitment to diversity and inclusion across race, gender, age, religion, and identity. We celebrate differences. We encourage different opinions and approaches to be heard, and we use these to build the best products in the world.

Your impact

As a start-up, Bolt6 provides a unique opportunity to work alongside and learn from people who have built multiple successful sports technology businesses.

Joining at our early stage of growth will enable you to become a key figure as we expand our teams, and enable you to work on all elements of the product life-cycle from ideation through to operational delivery. We take new ideas seriously, no matter where or who they come from.

Location

Having started during the Covid-19 pandemic, the majority of us work remotely from home. We also have an office in London and Winchester for those that prefer office working.

Interview Process

1. A short interview to check suitability, work history and interests. We can find out a bit more about you and give you an opportunity to ask questions about us!
2. We may give you a short take home assignment to check your technical competency and for you to see if you’d enjoy the work
3. Finally, we’ll invite you to a longer interview where we can discuss the assignment and take a deeper dive into your competencies
4. If we think you’d be a good fit and you like us then we’ll send you an offer!
