RF Test 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.

About the Role

We are seeking an RF Test Engineer to support the development, integration, and validation of spacecraft communication and RF systems. This role focuses heavily on flatsat and communications rack testing, RF subsystem characterization, automated test development, and environmental test campaigns. You'll work closely with RF, avionics, software, and integration teams to validate hardware performance from component-level bring-up through spacecraft-level environmental testing. This is a highly hands-on role requiring strong RF fundamentals, comfort operating advanced lab equipment, and the ability to troubleshoot complex integrated systems in fast-moving development environments.
