About the role
About Mach Industries Founded in 2022, Mach Industries is a rapidly growing defense technology company focused on developing next-generation autonomous defense platforms . At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 220 employees , we operate with startup agility and ambition. Our vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security.
The Role Mach Energetics is seeking a Propulsion Test Technician Lead to support the development, integration, and testing of next-generation propulsion and energetic systems for advanced defense applications. In this role, you will work directly on propulsion hardware and test infrastructure that enable rapid development, validation, and deployment of mission-critical systems. Key
Responsibilities Set up, operate, troubleshoot, and maintain propulsion test stands and associated ground support equipment, including high-pressure gas systems (GN2, GHe), pneumatic systems, and hydraulic infrastructure. Assemble, integrate, and test propulsion hardware including rocket engines, valves, regulators, feed systems, tubing, and propellant lines for development and qualification testing. Execute proof pressure, burst, leak, and flow testing procedures to validate propulsion hardware performance and structural integrity. Install, route, and calibrate instrumentation including pressure transducers, thermocouples, load cells, and other sensors used during propulsion test operations. Interface with data acquisition (DAQ) systems to support test setup, sensor verification, and collection of accurate test data during operations. Support hot-fire and cold-flow test campaigns by preparing hardware, performing system checkouts, and assisting with real-time test execution. Troubleshoot test anomalies and “no-go” conditions by identifying whether failures originate from hardware, instrumentation, fluid systems, or test setup configurations. Collaborate closely with propulsion and test engineers to rapidly iterate on hardware configurations and improve test reliability and operational efficiency. Maintain detailed records of test configurations, calibration activities, maintenance actions, and operational procedures. Adhere to strict safety procedures while operating around hazardous propellants, high-pressure systems, energetic devices, and other hazardous test environments. Support maintenance and upkeep of test facilities, cleanroom environments, tooling, and propulsion test infrastructure to ensure operational readiness. Required
