Test Engineer II

Advanced Reentry Technologies

Who We Are:

Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space. By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions.

The company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach.

Headquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry.

Design and procure test fixtures, structural interface plates, and test ground support equipment (GSE) using CAD software.

Configure, calibrate, and operate data acquisition (DAQ) hardware and sensor suites, including accelerometers, thermocouples, RTDs, and strain gauges.

Analyze post-test data, perform signal processing, and verify test results against design margins and structural requirements.

Lead the troubleshooting of test anomalies, instrumentation dropouts, and hardware failures, performing rigorous root-cause analysis.

Coordinate with external test facilities, vendors, and internal schedulers to ensure on-time test execution.

Required Qualifications

Bachelor’s degree in Aerospace Engineering , Mechanical Engineering, Electrical Engineering, or equivalent technical experience.

Typically 2 + years of hands-on experience in aerospace environmental testing (vibration, shock, thermal vacuum, or acoustic testing) at the subsystem or vehicle level.

Proven experience authoring comprehensive test plans, executing qualification/acceptance testing, and post-processing test data.

Direct, hands-on experience with data acquisition systems (DAQ), sensor signal conditioning, and instrumentation setup.

Experience designing mechanical test fixtures, interface plates, or test GSE in CAD (Siemens NX or equivalent).

Working understanding of aerospace testing standards .

Demonstrated excellent verbal and written communication skills.

Proven ability to work effectively in a fast-paced environment .

Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.

Desired Qualifications

Experience with spacecraft, launch vehicle, or high-reliability tactical hardware qualification campaigns.

Familiarity with test automation and data processing script development using Python, MATLAB, or LabVIEW.

Experience working with external test labs and managing vendor-facing test execution.

Prior experience working in startups and/or small independent teams.
