PCB Designer / Altium Librarian

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 a highly detail oriented PCB Designer who will also serve as the Altium Librarian, responsible for both high quality PCB layout and the integrity of our electronic component library. This role is critical to ensuring design consistency, manufacturability, and configuration control across all avionics hardware programs. The ideal candidate combines strong layout skills with a disciplined approach to library management, part creation, and data governance within a controlled engineering environment.

Responsibilities:

- Perform schematic capture support and PCB layout for complex, high-reliability electronics (multilayer, high-speed, mixed-signal, and power designs)

- Execute constraint-driven layout including impedance control, differential routing (e.g., Ethernet), and power integrity considerations

- Collaborate with electrical, mechanical, and thermal engineers to ensure design integration

- Generate and review fabrication and assembly drawings, stackups, and design notes

- Support DFM/DFA reviews with fabrication and assembly vendors

- Iterate designs based...
