Job description

Exowatt is revolutionizing the energy landscape for the AI era with our groundbreaking P3 system that captures solar energy, stores it as heat, and generates electricity on demand. Founded in 2023 and backed by leading investors including Andreessen Horowitz, Sam Altman, and Felicis, we're committed to providing clean, modular, and scalable power that meets the rapidly growing demands of AI infrastructure. Our mission is to make sustainable renewable energy always available and almost free, enabling technological advancement while protecting our planet.

We are seeking a Mechanical Engineer to join our optics team. The team owns the full design-to-commissioning lifecycle for our tracker hardware: precision optical elements and the structures that position them, solar tracking architectures, structural analysis under wind and gravity loading, and the instrumentation that turns prototypes into measured systems. The core problem is deceptively hard: hold optical precision on a large structure that moves all day, outdoors, under wind, gravity, and thermal swings, all at a cost that can scale to thousands of units.

At its core, this is a builder's role. Your main focus will be optomechanical assemblies: designing, fabricating, assembling, aligning, and testing the hardware that positions optical elements (lenses and mirrors, for example) on our trackers. The full loop is yours: idea to CAD to built hardware to test data, learning from what breaks and turning the next revision around in days, not months. You will spend most of your time hands-on in the shop, at the assembly bench, and on the test stand. The work spans structures, optics, precision assembly, sensors, and the code and AI agents that read them. This is an AI-native team: agents already drive our simulation campaigns and babysit our long-running tests, and we expect you to work at that level from day one. Everything around your hardware that is code, calculation, or documentation is something an agent should be running for you. Expect real ownership, a steep learning curve, and senior engineers who will review your work closely and push you to grow fast.

This position is based in Miami, FL. If selected, relocation to Miami, FL is required. Exowatt provides relocation assistance.

What We Offer:

• Competitive salary and equity options.
• Comprehensive benefits package, including health, dental, and retirement plans.
• A dynamic work environment that fosters creativity and innovation.
• Opportunities for professional growth and development in a rapidly evolving industry.
• Relocation assistance.
