Key skills for this 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.
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.
