We think of ourselves as the team behind the team, supporting the lifelong impact sports can have: the lessons in teamwork and dedication; the influence of inspiring coaches; and the opportunities to reach new heights. That's why we help teams from all over the world see their game differently. Our products make it easier for coaches and athletes at any level to capture video, analyze data, share highlights and more. Ready to join us? Your Role We're hiring an Engineer II to join one of our cross-functional product teams in our Athlete Performance group, which is focused on building cutting-edge solutions for athletes and sports teams that directly impact how they train, compete and achieve peak performance. In this role, you'll focus on building high-performance mobile applications and core data services across iOS and Android. You will help build and maintain hardware-agnostic communication interfaces to stream live sensor and optical tracking data to the cloud and mobile clients. You'll work on translating complex physical and biomechanical data into clear, digestible metrics that support real-time decision-making for elite coaches, athletes, and medical teams. In this position, you'll: * Work with a cross-functional team. You'll collaborate with Engineering, Quality Assurance, Product, Design and Scrum disciplines to deliver feature-rich mobile and the back-end services that power them. * Develop and deliver. You'll take ownership of specific features, defining low-latency communication interfaces across the stack and building user-facing application features that turn complex sensor data into clear, actionable insights. * Test new ideas.
