About Varda Low Earth orbit is open for business. Varda is accelerating the development of commercial space infrastructure, from in-orbit pharmaceutical processing to reliable and economical reentry capsules. Varda's W-Series vehicles are built, designed, and operated by Varda in-house, including the pharmaceutical processing payloads, the capsules, the C-PICA heat shields, and the satellite buses. From life-saving pharmaceuticals to more powerful fiber optics, there is a world of products used on Earth today that can only be manufactured in space. Varda is accelerating innovation in the orbital economy by creating both the products and infrastructure needed so space can directly benefit life on Earth. Our mission is to expand the economic bounds of humankind. Our team is uniquely suited to accomplishing this goal, with leadership and staff comprised of veterans from SpaceX, Blue Origin, major pharmaceutical companies and Silicon Valley. Varda was founded in January 2021 by Will Bruey and Delian Asparouhov with significant backing from world class investors including Khosla Ventures, Lux Capital, Founders Fund, Caffeinated Capital, General Catalyst, and Also Capital. Varda is headquartered in El Segundo, California, where we have offices and a production facility where our vehicles, equipment, and materials are built, integrated, and tested. Varda also has offices in Washington, DC and Huntsville, AL. Join Varda, and work to create a bustling in-space ecosystem. About this Role As the Thermofluids Engineer , you will be responsible for driving fluid system design for thermal management on the spacecraft through analysis, test, and validation. This role supports development and characterization of thermomechanical and fluid systems for payload, vehicle, and propulsion applications. You will be responsible for defining performance metrics, operational requirements, and hardware requirements for ground testing and flight. Day-to-day responsibilities include sizing thermofluid and system and component performance via hand calculations, simulation, and testing. Familiarity with typical thermomechanical hardware (valves, pumps, accumulators, heat exchangers, etc.), 0D and 1D fluid networks, and fluid system modeling is essential. Successful candidates thrive on solving hard problems, adapting to dynamic requirements, and collaborating across multiple domains. You will gain significant ownership, see your contributions rapidly come to life. This role is open at the Eng II level, with levels determined based on candidate experience.
