hirify.global develops in-space transportation vehicles and propulsion systems for orbital transport, payload deployment, precision reentry, and missions beyond Low Earth Orbit.

What you will do

• Own propulsion system development across requirements, architecture, design, analysis, implementation, integration, testing, and flight operations.
• Lead system-level trades covering fluids, thermodynamics, heat transfer, materials, mechanical design, component selection, and operations.
• Define system requirements, interfaces, verification strategies, configuration baselines, build and test scope, readiness criteria, and technical milestones.
• Plan and execute development, acceptance, and qualification test campaigns; review test and flight data and investigate anomalies.
• Identify technical and programmatic risks, develop mitigation strategies, and drive corrective actions to closure.
• Partner with manufacturing, integration, test, and mission operations teams; communicate technical decisions and mentor engineers.

Requirements

• Bachelor’s degree in engineering, physics, or a related technical discipline.
• 5+ years of professional experience in aerospace propulsion or a closely related field for the Senior level.
• Demonstrated experience developing bipropellant rocket propulsion systems.
• Strong foundation in fluid mechanics, thermodynamics, heat transfer, mechanics, and materials.
• Experience performing system-level engineering trades, including thermal-fluid analysis, materials selection, component selection, and operational analysis.
• Experience owning technical work from requirements definition through implementation and verification.
• Ability to lead effectively in small, highly collaborative, cross-functional teams.
• Strong written and verbal communication skills.

Nice to have

• Experience serving as the responsible engineer or technical lead for a flight propulsion system.
• Experience with spacecraft propulsion-system architecture, pressure systems, propellant management, valves, regulators, tanks, thrusters, or feed systems.
• Experience developing or executing propulsion development, acceptance, or qualification tests.
• Experience supporting launch or on-orbit spacecraft operations.
• Experience leading anomaly investigations, root-cause analysis, and corrective-action implementation.
• Experience mentoring engineers or establishing technical processes and best practices.
• For Staff-level candidates, a demonstrated record of setting technical direction, influencing across organizations, and delivering complex systems with limited oversight.
