Apex - Satellite Platforms Tech Stack

Configurable satellite buses for constellation-scale manufacturing

Defense and Space Manufacturing Los Angeles, California 201–500 employees Privately Held
apexspace.com LinkedIn

Apex designs and manufactures standardized satellite platforms (Aries, Nova, Comet) across LEO-to-GEO orbits. The tech stack reflects dual constraints of aerospace rigor and high-rate production: CAD/CAM tools (Altium, Siemens NX, CATIA, SolidWorks, ANSYS), embedded systems (C++, Rust, Embedded Linux, Yocto), and operations infrastructure (Kubernetes, Palantir Foundry, SAP). Active hiring is concentrated in engineering (77% of open roles) with balanced mid-to-senior distribution, signaling execution-phase scaling on avionics, GNC algorithms, and propulsion design while managing manufacturing yield and supply-chain risk.
