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.
Key Responsibilities
Lead the end-to-end design and development of high-temperature solar receivers optimized for solar field integration
Develop thermal and optical models to predict receiver performance, including flux distribution, heat transfer efficiency, and thermal stress analysis
Select and qualify materials capable of withstanding extreme temperatures (800°C–1000°C+), thermal cycling, and high solar flux environments
Design receiver geometries (cavity, external, tubular, particle-based) to maximize energy absorption while minimizing thermal losses and mechanical fatigue
Collaborate with solar collection and controls teams to optimize aiming strategies and flux distribution on receiver surfaces
Interface with heat exchanger and thermal storage engineers to ensure seamless integration of receiver output with downstream systems
Develop and execute testing protocols for receiver prototypes, including high-flux testing and accelerated life cycle evaluation
Drive design-for-manufacturing initiatives to reduce receiver cost and improve producibility at scale
Stay current with advances in receiver technology, high-temperature coatings, and selective absorber materials
Requirements
Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Materials Science, or related field; Master's or PhD preferred
7+ years of experience in thermal systems design, with significant focus on high-temperature receiver or heat exchanger development
Demonstrated expertise in solar thermal receiver design for tower-based or central receiver systems
Strong background in heat transfer (conduction, convection, radiation), thermodynamics, and fluid mechanics
Proficiency with thermal simulation tools (ANSYS, COMSOL, SolarPILOT, or equivalent)
Experience with high-temperature materials including ceramics, refractory metals, and advanced alloys
Hands-on experience taking receiver designs from concept through prototype testing and into production
Experience with molten salt, liquid sodium, or particle-based heat transfer media
Knowledge of selective absorber coatings and high-temperature surface treatments
Familiarity with optical modeling and ray-tracing software for flux analysis
Background in solar field optimization and aiming point strategies
Publications or patents in solar thermal receiver technology
