Original job description

About Aether

Aether is building a comprehensive AI-driven platform for the built world. Our core software is used by solar, roofing, and heat pump companies to deliver advanced 3D modeling, simulation, quoting, and financing tools - all in one powerful interface. We combine deep technical rigor with real-world utility, leveraging physics-based modeling, AI, and scalable infrastructure.

Founded by alumni of UC Berkeley, École Polytechnique, and ETH Zurich, we bring experience from leading energy and software companies.

Aether is a recent graduate of YCombinator, and has raised over $6M in funding. Check us out: https://www.aethergtm.com

About the Role

We're looking for a sharp, ambitious Frontend Engineer with strong CAD / 3D skills to take ownership of key parts of our in-browser solar configurator - a Three.js-powered design engine that lets users model rooftops and design solar systems in 3D.

You'll join our existing configurator team and work directly with our CTO, computational engineers, and product team. While the CAD engine is already in production, we’re building entirely new 3D functionality (e.g. full 3D site visualization, generative design workflows, performance tuning, etc.) that will require strong technical skill and creativity.

Beyond 3D, you'll also take on regular frontend features across the Aether platform - this is a hybrid CAD + product role for someone excited to stretch across UX, engineering, and real-time geometry.

We use Three.js and React Three Fiber (R3F) as part of our tech stack, and expect deep familiarity with 3D frontend work and strong problem-solving instincts. If you're looking for a role where you can own complex features, help scale a production configurator, and work on tools that power the clean energy transition - this is it.

What You’ll Do

Contribute to and expand our Three.js-based solar configurator (CAD interface)
Build and optimize 3D geometry tools and visual design workflows
Take ownership of both new CAD/3D features and regular product-facing frontend tasks
Collaborate with backend and computational teams on data flows, simulations, and rendering
Translate solar physics concepts into usable design tools
Help define best practices and architecture for frontend + 3D stack
Drive key UX and interaction decisions with design team
Ensure configurator is performant, stable, and intuitive across edge cases

Requirements

3+ years of experience building interactive frontends or 3D web apps
Strong knowledge of Three.js, React Three Fiber (R3F), WebGL, and modern JavaScript (ES6+)
Solid intuition for UX and interface design in 3D space
Strong math/geometry background (vectors, transforms, spatial reasoning)
Experience with modern frontend tools (React, Vite, Git, etc.)
Comfortable working in fast-paced, high-ownership environments
While you’ll own major 3D features, you’re also comfortable working in tandem with another CAD engineer on shared systems and workflows
You’re comfortable jumping between deeply technical CAD logic and more traditional product UI work.

Bonus Points

Background in engineering, physics, math, or computational science
Experience with rooftop design tools, CAD interfaces, or solar-related software
Familiarity with performance optimization for real-time rendering
Experience with shaders or low-level WebGL
Understanding of solar/energy data, simulations, or ML integration

Why Join Aether

Build tools that directly accelerate clean energy adoption
Own core parts of a 3D design engine used by real solar installers
Work with a fast-moving, talented team across design, engineering, and ML
Help shape a critical vertical in a scaling YC-backed startup
