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 Senior Embedded Software Engineer on Apex's Flight Software team, you will write the software that runs on the custom avionics hardware powering our satellite buses. You will work closely with avionics, GNC, propulsion, and hardware engineers to design and deliver the software for the components that make up the spacecraft, owning that software from the design phase all the way through flight. You will contribute across the full breadth of development, from architecting new systems and prototyping early ideas to writing the mission critical code that ultimately flies.
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.
Senior: $155K - $210K
Staff: $200K - $250K

Apex was founded to solve one of the space industry’s biggest challenges: the satellite production bottleneck. While reusable launch vehicles have solved many orbital access challenges, scaled satellite manufacturing remains a critical bottleneck to constellation deployment. Apex’s solution: productized, configurable spacecraft designed for manufacturing and delivered at scale.
Our three product lines — Aries, Nova, and Comet — serve a broad range of customer missions through configurable designs optimized for operations from LEO to GEO. These platforms will ensure the U.S. and its allies maintain a strategic advantage in the New Space Race, providing the foundation for today’s most critical constellations and tomorrow’s next-generation architectures.
Today, Apex is delivering standardized satellite buses at scale by blending traditional aerospace techniques with new space mentalities and lessons from high-rate terrestrial manufacturing. Since our founding, our focus remains the same: short lead times, constellation-scale production, and highly reliable spacecraft.
We can’t wait to see what you build on Apex’s platforms. Let's get to orbit.
