About Us
We're building a co-pilot for hardware designers. Our mission is to enable millions of hardware designers + engineers to iterate through designs 1000x faster. (Our system solves highly ill-conditioned 500M degree of freedom in 60 seconds, without hallucinations)
We are building our geometry + physics-driven foundation model for nm to cm scale designs → First model shipped and now expanding!

About the Role
We’re looking for an experienced Front-End Engineer with serious Three.js skills and a solid understanding of how to bring interactive 3D content into the modern React stack using React Three Fiber.
If you're the kind of developer who loves solving complex rendering challenges, building immersive visualizations, and turning 3D data into intuitive, performant interfaces—this role is for you.
You’ll be a key contributor to a product that blends UI/UX precision with real-time 3D, leveraging Next.js for application structure and performance, and Three.js/R3F for rendering.
Responsibilities
Build and maintain front-end features using React, Next.js, and React Three Fiber.
Design and implement interactive 3D scenes using Three.js, with an emphasis on performance and responsiveness.
Integrate shaders, materials, cameras, lighting, and geometry into a coherent user-facing application.
Ensure rendering logic coexists cleanly with UI components and state management.
Write reliable, testable code using Jest and Playwright.
Participate in code reviews and technical discussions with a focus on maintainability and scalability.
-
Contribute to performance tuning of large or complex 3D scenes.
Required Qualifications
3+ years of professional front-end experience using React and modern JavaScript/TypeScript.
1–2+ years of hands-on Three.js experience (not just tutorials—real-world projects).
Experience with React Three Fiber (R3F) and how it bridges Three.js into React’s declarative model.
Familiarity with shaders (GLSL), custom materials, and WebGL rendering pipelines.
Strong understanding of component architecture, hooks, and React ecosystem tools.
Working knowledge of Next.js for routing, performance optimization, and SSR.
A strong eye for UI/UX, particularly in the context of 3D interaction.
Comfortable writing tests and practicing clean coding principles.
Nice to Have
Experience with post-processing effects, instancing, or GPU optimization techniques.
Familiarity with state management with React Context.
Experience working with canvas-based or shader-heavy applications.
Contributions to open-source libraries in the Three.js or React ecosystem.
Compensation Range: $180K - $220K
