You will be trusted to figure things out, spot issues early, and drive solutions without heavy process or close oversight.

Creative problem-solver with strong critical thinking and troubleshooting skills who learns quickly and takes initiative. Strong communicator and collaborator who makes the people around them better. Interest in or experience with the Sports and/or Sports Betting industry. Preferred Qualifications: Experience working on B2C products at a small company or startup. Experience with at-scale integration of 3rd party APIs. Experience with microservices architecture and client-server communication (REST, Server Sent Events, websockets, etc.).
