About Us

At Challenger we believe all gamers should have an opportunity to enhance their experience with cash contests without radically changing how/where/when they play. With this belief guiding us, we’ve built a first of its kind in-game contest engine that automatically tracks results for users and provides real-time notifications for scores. This is made possible through the combination of our Windows app for contest configuration and data collection, our AI (computer vision, deep learning, machine learning) to understand in-game interactions, and our python data processing running on a performant and scalable GCP tool chain.

As an Engineer at Challenger you will be able to use a combination of leading edge technologies to deliver an experience unlike any other in the video gaming market. We’re a small team of passionate technologists and gamers, chasing ambitious goals in a very fun industry that has not yet realized the potential of cash gaming.
