Summary: The Senior Front-End Developer role focuses on designing and developing advanced 3D web applications using technologies like Three.js or Babylon.js. The position requires building high-performance applications that visualize biomechanical motion capture data and deliver interactive user experiences. The developer will collaborate with backend teams and optimize rendering performance while translating UX/UI designs into responsive applications. A strong background in front-end development and experience with real-time data integration is essential for success in this role.

Key Responsibilities:

  • Design and develop advanced 3D web applications using Three.js or Babylon.js.
  • Build a high-performance, real-time application that visualizes biomechanical motion capture data.
  • Build real-time rendering pipelines for visualizing motion capture and biomechanical data.
  • Integrate 3D visualizations with video overlays, annotations, and data-driven insights.
  • Collaborate with backend teams to consume APIs and streaming data (REST, WebSockets, etc.).
  • Optimize rendering performance to meet near real-time constraints.
  • Translate UX/UI designs into responsive, high-quality interactive experiences.
  • Implement reusable, scalable front-end architecture and components.
  • Troubleshoot and resolve performance bottlenecks across devices and browsers.
  • Contribute to technical design discussions and mentor junior developers.

Key Skills:

  • Overall, 12+ years of experience required.
  • 5+ years of professional front-end development experience.
  • Strong hands-on experience with Three.js or Babylon.js.
  • Deep understanding of WebGL, 3D math (vectors, matrices, transformations), and rendering pipelines.
  • Proficiency in JavaScript/TypeScript, HTML5, and modern front-end frameworks (e.g., React, Angular, or Vue).
  • Experience integrating with APIs and real-time data streams.
  • Familiarity with performance optimization techniques for graphics-heavy applications.
  • Strong debugging and problem-solving skills.
  • Preferred: Experience working with motion capture, biomechanics, or video processing pipelines.
  • Preferred: Familiarity with shader programming (GLSL) and custom materials.
  • Preferred: Knowledge of Azure cloud services or similar cloud platforms.
  • Preferred: Experience with .NET-based backends and data integration workflows.
  • Preferred: Understanding of data visualization principles and interactive UX design.
  • Preferred: Experience working in sports tech, health tech, or simulation environments.
  • Preferred: Prior experience delivering MVPs under tight timelines.
