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 as 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.
We are seeking a seasoned spacecraft electrical engineer to work on a closely integrated team who will drive the design of the avionics, flight computer and power systems to meet the requirements of our bus. You will have an opportunity to approach this from a clean sheet design and inform coupled trades across the vehicle architecture. You will be innovative in your approach to push the limits of design and performance, while disrupting and making an impact on the industry. This role reports directly into the Director of Spacecraft.
