About The Position

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. As a member of the flight Software team, you will design, develop, and own the software driving the autonomous operation of Apex's satellite buses. You will be responsible for developing mission critical systems that operate reliably 24/7, ensuring that Apex's spacecraft continue to operate in all scenarios. In this role, you will work closely with both internal teams and external customers, aligning your solutions with company objectives and user requirements. We are looking for motivated engineers who are eager to solve complex problems with a focus on practicality and scalability, and who thrive in a dynamic, fast-paced environment.
