Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge. For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles. Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more. We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet.  ABOUT THE ROLE Apex is looking for a Materials and Processes (M&P) Engineer who will serve as the company technical focal for metallic materials and associated manufacturing processes used on spacecraft, propulsion systems, mechanisms, structures, avionics hardware, and flight-support equipment essential for our satellite operations. The M&P engineer will define product requirements, inform material and design trades, perform analyses and testing on materials, drive test campaigns, and develop a materials database and usage list. You will validate decisions through prototypes and build and qualify flight hardware as we scale volume.
