Job Description
Title: Front-End Engineer (React Three Fiber · AI-Assisted Development)
Location: Hoboken, NJ Onsite
About the project
We are building a browser-based 3D virtual science lab. Students assemble apparatus, perform experiments, and are assessed on their technique — all rendered in real time with React 19, React Three Fiber (Three.js), and Zustand, built with Vite. The simulation runs on ordinary school hardware, including low-end Chromebooks, so it has to be both convincing and fast, and its behavior has to be deterministic enough to score reliably.
What you'll do
- Build and own complex React Three Fiber features: interactive 3D equipment, a selection-driven action system, real-time visual effects, and the UI around them.
- Keep the app fast on low-end hardware — profile and tune the render
