Company

hirify.global develops commercial space infrastructure, including pharmaceutical-processing payloads, reentry capsules, heat shields, and satellite buses.

What you will do

• Own pharmaceutical manufacturing payloads from concept through design, integration, launch, in-orbit operation, reentry, recovery, and iteration.
• Design precision fluid systems using valves, pumps, pistons, manifolds, tubing, fittings, seals, filters, sensors, and thermal-control hardware.
• Perform fluid, thermal, structural, and mechanism analyses using hand calculations, Python, MATLAB models, and FEA.
• Build, instrument, and test prototype and flight hardware for flow, mixing, filtration, sealing, leakage, pressure drop, thermal stability, contamination sensitivity, and reliability.
• Translate inputs from pharmaceutical science, business development, and spacecraft subsystem teams into payload requirements.
• Develop requirements, interface-control documents, verification plans, test reports, recovery procedures, and mentor junior engineers and interns.

Requirements

• Bachelor's degree in Mechanical, Aerospace, Mechatronics, Biomedical, Chemical, or a related engineering discipline.
• 4+ years of experience designing, integrating, testing, and troubleshooting electromechanical hardware.
• Strong mechanical and fluid systems expertise with breadth in an adjacent discipline such as avionics, software, thermal systems, optics, test, or precision instrumentation.
• Experience delivering hardware for rigorous environments such as aerospace, defense, semiconductor manufacturing, or biotech manufacturing.
• Experience with precision fluid-handling components, compact fluidic assemblies, thermal-control hardware, and integrated hardware development.
• Must be authorized to work in the United States as a U.S. person eligible to access export-controlled technology under ITAR requirements.

Nice to have

• Full-cycle ownership of precision fluid-handling hardware for spacecraft, semiconductor, biotech, analytical-instrument, or medical-device applications.
• Experience with P&IDs, fluid schematics, component sizing, pressure-drop analysis, leak testing, flow characterization, and 0D/1D fluid or thermal modeling.
• Experience with aerospace environmental testing, including vibration, TVAC, and EMI/EMC.
• Familiarity with microgravity fluid behavior, capillary-driven flows, two-phase flow, cGMP principles, cleanroom practices, or regulated hardware environments.

Culture & Benefits

• Regular full-time employment with flexible PTO and 12 paid holidays.
• Company-paid medical, dental, and vision insurance with FSA and employer-matched HSA options.
• Parental leave, family-building support, wellness reimbursement, and sponsored medical memberships.
