We are looking for a Senior Mechanical Engineer – Test with 4+ years of experience to own the mechanical test and qualification system for our spacecraft hardware. This is not a role for running pre-defined procedures — you will be responsible for designing, building, and scaling the entire test infrastructure from scratch, and defining what it means for our vehicle to be flight-ready.

This is a deeply hands-on role at the intersection of mechanical systems, instrumentation, and data acquisition, ideal for someone who has built test systems themselves and wants full ownership in a fast-moving startup environment.

What will you be doing?

• Own the end-to-end test and qualification pipeline for spacecraft components and vehicles, from requirements definition through execution, data analysis, and certification

• Design and build custom mechanical test infrastructure, including fixtures, jigs, stands, and portable test racks integrating sensors, power, and control systems

• Define and execute test strategies and plans across a wide range of environments, including load, vibration, shock, deployment, and drop testing

• Develop and implement data acquisition and control systems (LabVIEW, Python, MATLAB), and perform data reduction and analysis to drive engineering decisions

• Determine instrumentation approaches (strain gauges, load cells, displacement, temperature, etc.) and work cross-functionally to integrate sensors and wiring

• Partner closely with design, systems, and manufacturing teams to ensure tests are meaningful, traceable to requirements, and representative of real flight conditions

• Build the internal test standards, processes, and documentation required to qualify hardware for flight and meet regulatory and certification requirements
