About Apex

Apex manufactures satellite buses at scale, combining software, vertical integration, and hardware designed for manufacturing. Our spacecraft enable earth observation, communications, and other applications that provide humankind access to space.

The Role

You will own the validation of flight hardware from first build through system-level testing. This is a highly multidisciplinary role focused on structural and mechanical testing, with strong crossover into electrical and system-level validation.

Responsibilities

Own structural test strategy and execution across components, subsystems, and fully integrated spacecraft
Develop and operate fluid, hydraulic, and pressurized systems, including high-pressure and cryogenic environments
Design and integrate data acquisition and instrumentation (strain gauges, load cells, pressure transducers, thermocouples)
Write and automate test procedures and scripts (primarily Python) for execution and data analysis
Lead test operations end-to-end, including setup, execution, and post-test review
Troubleshoot hardware and drive root cause analysis on structural test failures
Partner cross-functionally with design, analysis, avionics, and manufacturing to close the loop between test results and design

Requirements

Bachelor's degree in mechanical, aerospace, or related engineering field
3+ years of experience in spacecraft, launch vehicle, or complex structural testing
Background designing large-scale structural test stands or load application systems
Strong fundamentals in structural mechanics, including strength, stability, and fatigue
Experience with structural analysis (hand calcs and/or FEM) and test correlation
Hands-on experience with instrumentation and lab equipment (strain, load, pressure, thermal measurements)
Experience designing, building, or operating structural test systems and hardware
Experience with test automation and scripting (Python or similar)
Ability to operate in fast-paced, high-ownership environments with evolving requirements

Nice To Haves

Experience with environmental testing (TVAC, vibration, shock, EMI/EMC)
Familiarity with NX/Teamcenter, Nastran, or ANSYS
Experience working with high-pressure or cryogenic systems
