Company

hirify.global is a defense technology startup founded in 2023 that develops autonomous, scalable, decentralized defense platforms and advanced propulsion systems.

What you will do

• Design and maintain propulsion test stands and ground-support systems for static-fire and development testing.
• Plan, lead, and support component-level and full-scale integrated rocket-engine hot-fire test campaigns.
• Collect and analyze pressure, temperature, and thrust data using high-speed sensors and instrumentation.
• Validate propulsion-system performance against specifications and support rapid hardware iteration.
• Execute hazardous operations involving high-pressure systems and cryogenic propellants, including liquid oxygen.
• Collaborate with engineering, manufacturing, and flight-test teams during development programs.

Requirements

• 3+ years of experience in propulsion, aerospace, automotive, industrial testing, mechanical development, or a related technical environment.
• Experience with mechanical assemblies, fluid or pressure systems, propulsion hardware, test operations, troubleshooting, and hardware iteration.
• Ability to interpret technical drawings, schematics, assembly instructions, and test procedures.
• Hands-on experience with shop equipment, torque tools, tubing tools, pressure equipment, and diagnostic instrumentation.
• Strong systems-thinking and troubleshooting skills, with willingness to work extended hours and travel short-term during active campaigns.
• Must be authorized to work in the United States; employment may require authorization to access U.S.-controlled technology under EAR and ITAR without export-license sponsorship.
