Senior Engineer, FitXR

• You’re a proactive, product-minded engineer with:
• Strong React experience in production environments
• Proven ability to own projects end-to-end, balancing delivery speed with solid engineering principles
• Experience working in small, cross-functional teams
• Excellent communication - you keep people in the loop, surface blockers early, and stay cool in chaos
• Comfort with ambiguity - you can build clarity where none exists
• Curiosity about 3D, gaming, or VR - bonus if you’ve built something weird and fun before
• Perspective of AI as a teammate, not a threat - you’re leveraging AI to speed up your workflow, generate tests and help prototype ideas faster

• Help define how we build - bringing product thinking and technical insight to every sprint
• Share knowledge, raising the overall level of code craft and collaboration
• Push the limits of our React–Unity integration to unlock even richer player experiences
