Role summary
This position is ideal for an experienced software engineer specializing in modern web technologies who gets excited about building AI-assisted workflows. You will join a cross-functional team at the Advanced Technology Development team, contributing to a Web 3D application used by thousands of orthodontists worldwide to design Invisalign® treatment plans. The stack is React, Three.js, and WebGL on the front end, with a C++ computational engine on AWS at the back. We use tools like Claude Code daily for development, testing, and tooling, and we are actively building AI-powered product features. If you have strong opinions about how AI should reshape the software development lifecycle, you will have a platform to act on them.


  • Build and ship 3D interactive features that orthodontists use daily to visualize, manipulate, and refine treatment plans in the browser using React, Three.js, and WebGL.
  • Develop with AI as your copilot. We use Claude Code daily for feature development, refactoring, test generation, and code review preparation. You will help define and evolve our AI-augmented development practices.
  • Architect frontend systems at scale that handle complex 3D, working with video streams, and seamless integration with a C++ computational backend via AWS services.
  • Prototype AI-powered product features such as intelligent treatment suggestions, automated plan validation, and smart UI that adapts to clinical workflows.
  • Collaborate across disciplines with clinical scientists, UX designers, ML engineers, and QA to deliver solutions that directly improve patient outcomes

  • BS/MS in Computer Science or equivalent hands-on experience.
  • 8+ years of professional software engineering experience with a strong frontend focus.
  • Hands-on experience with 3D web technologies: Three.js, WebGL, or equivalent rendering frameworks.
  • Enthusiasm for AI-assisted development tools like Claude Code, Copilot, or Cursor and can articulate how AI changes the way you write software.
  • Excellent communication skills in English—you can explain complex 3D rendering concepts to a clinical scientist and make it make sense.
  • Strong CS fundamentals: algorithms, data structures, system design, and performance optimization.
