Sr. Software Engineer; 3D Web

Role Summary

This position is ideal for an experienced software engineer specializing in modern web technologies who is excited about building AI‑assisted workflows. You will join a cross‑functional team in the Advanced Technology Development department, contributing to a Web 3D application used by thousands of orthodontists worldwide to design Invisalign treatment plans. The stack includes React, Three.js, and WebGL on the front end, with a C++ computational engine on AWS at the back.

We use AI tools such as 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, using Claude Code 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, work with video streams, and seamlessly integrate 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 the ability to articulate how AI changes the way you write software.
• Excellent communication skills in English—able to explain complex 3D rendering concepts to a clinical scientist and make them understandable.
• Strong CS fundamentals: algorithms, data structures, system design, and performance optimization.
