Company

hirify.global develops commercial space infrastructure, including in-orbit pharmaceutical processing, reentry capsules, heat shields, and satellite buses, with vehicles and equipment built, integrated, and tested in-house.

What you will do

• Own end-to-end manufacturing processes for propulsion systems, including valve assembly, tube fabrication, pressure vessel integration, and engine integration.
• Develop and maintain work instructions, process travelers, and process specifications for high-pressure fluid systems and propulsion hardware.
• Improve propulsion build processes, production cadence, work-cell layouts, and product flow for concurrent vehicle builds.
• Implement cleanliness protocols, contamination control procedures, and propellant compatibility requirements.
• Lead root cause analysis and corrective actions for leaks, contamination findings, assembly defects, and other propulsion non-conformances.
• Define tooling and test equipment requirements and collaborate with design engineering and supply chain to resolve hardware quality issues and prevent schedule delays.

Requirements

• B.S. in Mechanical Engineering, Manufacturing Engineering, or a related discipline, or equivalent professional experience, typically 3–6+ years.
• At least 3 years of manufacturing experience with propulsion systems, fluid systems, or high-pressure hardware in aerospace or a related industry.
• Hands-on experience with tube fabrication, tube bending, tube fitting installation, and high-pressure fluid-system assembly.
• Familiarity with propulsion cleanliness requirements, cleanliness verification methods, and contamination-control procedures.
• Experience reading and interpreting engineering drawings, P&IDs, and assembly models for fluid systems.
• Strong first-principles problem-solving skills, including diagnosing propulsion build defects and driving corrective actions to closure.
• Physical ability to regularly lift 25 lbs., bend, stoop, and stand for extended periods while working directly with flight hardware.
• U.S. person status is required to access export-controlled technology; employees must be lawfully authorized to work in the United States.

Nice to have

• M.S. in Mechanical Engineering specializing in Fluid Mechanics, Process Engineering, or a related discipline.
• Experience manufacturing and assembling propulsion systems for launch vehicles, spacecraft, or hypersonic vehicles, including valve assembly and pressure vessel integration.
• Experience testing high-pressure fluid systems or qualifying assemblies involving energetics and explosives.
• Experience with metals, composites, and plastics used in propulsion systems.
• Experience with propulsion manufacturing methods including welding, orbital welding, machining, and additive manufacturing.
• Experience with non-destructive examination, including ultrasonic testing, dye penetrant, and X-ray inspection.
• Experience transitioning propulsion assemblies from development to production while increasing build rate.
• Familiarity with hazardous-material handling and safety protocols for propellant loading and propulsion acceptance testing.

Culture & Benefits

• On-site work at the El Segundo production facility.
• Eligibility for incentives in the form of stock options and/or long-term cash awards.
• Inclusive equal-opportunity workplace with employment decisions based on merit, qualifications, and performance.
