- A strong belief that testing, observability, and clean architecture are not optional.
- An innate curiosity and a passion for solving complex problems, whether they're in code or on a whiteboard.
Why You'll Love Working Here:
This isn't just another backend role. This is a chance to put your fingerprint on the foundational technology of a fast-growing company in the exciting world of sports tech and gaming. You'll have the autonomy to make big decisions and the support of a team that's all-in on the mission.
