Principal GNC Engineer

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. 

Based out of Apex’s global headquarters in Playa Vista, the Principal Guidance Navigation and Control (GNC) is responsible for leading GNC development for Apex’s growing fleet of spacecraft platforms. You will demonstrate a firm grasp of spacecraft GNC concepts and applications. You will work with all facets of the engineering life cycle: spacecraft concept and algorithm development, flight software implementation, subsystem requirements development, detailed GNC design, subsystem integration & test (I&T), and vehicle I&T. You will be responsible for planning and maintaining the development schedule to support the Space Systems Control Software organization in executing leading edge programs and products. You will work closely with related teams, including Systems, Avionics, Flight Software, Mission Operations, and Ground Software. You will also directly interact with customers to ensure mission success.
