About the role

Apex is seeking a highly technical Mechanisms & Actuators Engineer to support the development of spacecraft electromechanical systems, with a primary focus on Solar Array Drive Assemblies (SADAs), reaction wheels, and other high reliability mechanisms critical to spacecraft operation.
This role will own and drive the development, integration, testing, and qualification of flight mechanisms and actuator systems from early architecture through delivery. You'll work across mechanical, avionics, controls, GNC, and production teams to develop reliable, scalable, and flight-proven electromechanical hardware capable of surviving demanding space environments and mission lifetimes.
We're looking for someone who understands how to design and deliver electromechanical systems, who can operate effectively in a fast-paced spacecraft development environment.

Conceptualize, design, assemble, and test spacecraft electromechanical systems including SADAs, reaction wheels, deployment actuators, and other high-reliability mechanisms.
Own actuator and mechanism development from concept through qualification and flight delivery.
Support architecture development, trade studies, component selection, and performance analysis for flight mechanisms and motor-driven systems.
Collaborate closely with avionics, controls, GNC, and software teams on actuator electrical, mechanical, and controls interfaces.
Support mechanism integration, hardware bring-up, troubleshooting, and environmental testing including vibe, TVAC, and life cycle testing campaigns.
Drive root cause investigations and failure analysis activities related to actuator or mechanism performance.
Develop manufacturing, assembly, and test strategies for scalable spacecraft production.
Partner with suppliers and internal teams on component development, qualification, procurement, and hardware validation.
Contribute to spacecraft-level integration efforts and support flight hardware through build, test, and launch campaigns.
Create and maintain design documentation, requirements, interface definitions, test plans, and verification reports.

5+ years of experience developing electromechanical systems, mechanisms, rotary actuators, for aerospace or other high-reliability applications.
Experience owning or contributing to the development and delivery of long-life electromechanical actuators for space vehicles.
Strong understanding of motors, bearings, geartrains, and rotating systems
Hands-on experience with mechanism integration, testing, troubleshooting, and hardware bring-up.
Familiarity with environmental qualification testing including vibration, thermal vacuum, shock, and lifetime testing.
Strong analytical and problem-solving skills with the ability to debug complex system-level issues.
Ability to operate effectively in fast-paced development environments with high ownership and autonomy.
Experience with Solar Array Drive Assemblies (SADAs), reaction wheels, control moment gyroscopes, gimbals, or deployment systems
Familiarity with motor driver electronics, embedded control implementation, and/or motor feedback devices
Experience with rotor dynamics analysis and/or rotary balancing techniques

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.
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.
