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 seeking an experienced and detail-oriented Senior Environmental Test Engineer specializing in environmental testing and checkouts. This candidate will play a critical role in ensuring the reliability and performance of our space systems and components through testing procedures. You will be responsible for designing, implementing, and managing test protocols & equipment that focus on simulating environmental conditions our spacecraft will encounter during their lifecycle
