Principal Guidance, Navigation, and Controls Engineer

About VardaLow 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 RoleAs a Principal Guidance, Navigation, and Controls Engineer, you will own the full life cycle of GNC development at Varda, from design through to unit, hardware-in-the-loop, on-vehicle functionality, and flight testing. You will perform system analyses, including simulations and Monte Carlo, to satisfy specifications and requirements and to drive system-level architectural and business decisions. You will contribute to a sophisticated multi-degree of freedom in-house aerospace simulation and test framework and develop and maintain design descriptions and supporting documentation.
