Job Description

Aetherflux's mission is to deliver energy to planet Earth. Our work will make energy more accessible, establish American energy independence, power underdeveloped and disaster-stricken areas, and protect American warfighters. Background Aetherflux is taking a new approach to an old idea called space solar power. Our constellation of satellites will collect sunlight in Low Earth Orbit, convert it to electricity, and transmit power through infrared lasers to ground stations, providing reliable energy access where traditional delivery is expensive, challenging, or dangerous. Current energy systems rely on complex logistics and outdated infrastructure, making them vulnerable to natural disasters, extreme weather, and physical and cyber attacks. Aetherflux overcomes these challenges by enabling direct, on-demand, secure, and scalable 24-hour energy distribution from space. This can revolutionize energy generation and delivery, and enable new capabilities as we deliver power to remote regions, military bases, bespoke operations, and unmanned autonomous systems. Baiju Bhatt, who also co-founded Robinhood, founded Aetherflux in 2024. Inspired by his father’s career at NASA, Baiju earned his B.S. in Physics and M.S. in Mathematics at Stanford before starting Robinhood, now a public company that has helped over 20 million Americans access the financial system. Aetherflux is currently self-funded through a $10 million investment from Baiju. This is an ambitious mission that demands extraordinary talent. Aetherflux’s team has worked at places like Robinhood, SpaceX, NASA, Anduril, JPL, and the U.S. Navy, and is based in San Carlos, CA. If you're ready to solve complex technical challenges and help build the most important energy company in the world, we want to hear from you. Overview The Thermal-Mechanical Engineer will design, analyze, and implement thermal management solutions for our space-based power transmission platform.

Heat Transfer Optimization: Design heat exchangers, radiators, and phase change materials for optimal thermal performance. Vacuum & Radiation Considerations: Evaluate the effects of vacuum, radiation, and extreme temperature fluctuations on spacecraft thermal systems. Thermal Testing & Validation: Develop and execute thermal vacuum chamber tests, thermal cycling tests, and in-orbit validation plans. Integration with Mechanical & Electrical Systems: Collaborate with mechanical and electrical engineers to ensure seamless integration of thermal management solutions. Material Selection: Identify space-grade thermal materials, coatings, and insulation for spacecraft structures. Reliability & Safety: Conduct failure mode analysis and implement redundancy in thermal control systems. Collaboration: Work with optics, avionics, and propulsion teams to address thermal constraints in system design. Basic Qualifications Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field. 3+ years of experience in thermal engineering, thermal analysis, or spacecraft thermal systems. Proficiency with thermal modeling software such as ANSYS, Thermal Desktop, COMSOL, etc. Strong understanding of heat transfer principles, including conduction, convection, and radiation in space. Experience designing and testing radiators, heat pipes, and phase-change materials. Knowledge of spaceflight hardware qualification and environmental testing. Familiarity with vacuum chamber thermal testing and in-orbit thermal management strategies. Preferred Qualifications Master’s or PhD in Mechanical Engineering, Aerospace Engineering, or a related discipline. 5+ years of experience designing thermal systems for spacecraft, aerospace, or high-power laser applications. Experience with cryogenic cooling, thermoelectric cooling, and advanced thermal coatings. Hands-on experience with spacecraft thermal integration and flight testing. Familiarity with radiation shielding techniques and space-qualified thermal materials. Strong analytical skills and ability to solve complex thermal design challenges.
