Ground Test Engineer II

Who We Are:  

Inversion builds advanced reentry systems to deliver next-generation capabilities from space.
 
Our mission is to make Earth radically more accessible by turning Low-Earth Orbit into an on-demand logistics domain. We see space not as a destination, but as a platform — one that unlocks unprecedented speed and global reach.
 
Our spacecraft are designed to deliver payloads anywhere on Earth in under an hour, operating through extreme reentry conditions and landing with high precision. These systems open the door to new ways of testing, delivering, and operating at hypersonic speeds.
 
Inherently dual-use, our technology is built to meet urgent national security needs while laying the groundwork for future commercial applications. Backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, and working with partners such as the U.S. Space Force and NASA, Inversion is pushing the boundaries of what’s possible in space-based defense and logistics.

What You’ll Do: 
Ground test is how Inversion builds confidence in new reentry systems before flight. As a Ground Test Engineer II, you will lead and support critical test campaigns that shape vehicle design, validate models, and retire technical risk. This role will focus on arc jet testing, wind tunnel coordination, post-test data processing, and a broad range of additional ground test activities for reentry vehicles. In this role, you will: 

• Lead arc jet test campaigns from early planning through execution, post-test inspection, and data review. 

• Coordinate wind tunnel testing with outside facilities, vendors, and internal engineering teams. 

• Develop and own test plans, procedures, instrumentation layouts, reports, and analyses. 

• Process and reduce test data to generate clear technical conclusions and actionable recommendations. 

• Support additional ground test activities for reentry vehicles including subsystem, component, and integrated hardware testing. 

• Coordinate logistics, schedules, facility interfaces, and hardware readiness for external test campaigns. 

• Lead test operations with a high degree of safety, accountability, and responsibility. 

Required Qualifications: 

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

• 2+ years of applicable hands-on experience testing hardware systems. 

• Experience with instrumentation, data acquisition, and post-test data processing. 

• Experience writing test procedures, reports, and technical documentation. 

• Demonstrated excellent verbal and written communication skills. 

• Capable of operating safely and effectively in fast-paced test environments. 

• Capable of working in a dynamic, fast-paced startup environment. 

Desired Qualifications: 

• Experience with arc jet, high-enthalpy, or hypersonic ground test campaigns. 

• Experience coordinating or executing wind tunnel tests. 

• Experience instrumenting hardware with thermocouples, pressure sensors, strain measurements, or other aerospace test sensors. 

• Experience using Python, MATLAB, or similar tools for data processing and analysis. 

• Experience with aerospace qualification or development testing for flight hardware.
