iRocket (Innovative Rocket Technologies Inc.) is pioneering fully autonomous, fully reusable small launch vehicles to enable responsive, lower-cost access to space. We combine advanced propulsion, reuse, and sustainable propellant technologies to push the frontier of commercial space.
The Role:
We are seeking a Propulsion Engineer to join our propulsion team and contribute to the design, development, testing, and qualification of propulsion systems for our launch vehicles. You will work closely with integration, test, design, and manufacturing teams to bring propulsion systems from concept to flight readiness.
Support design, development, and testing of propulsion systems (e.g. liquid rocket engines, pressure-fed or pump-fed systems, component-level systems)
Participate in test campaigns, including planning, instrumentation, execution, and post-test analysis
Develop and maintain test procedures, control sequences, and configuration files for propulsion testing
Troubleshoot issues in propulsion subsystems (fluid, mechanical, thermal) during testing and integration
Collaborate with cross-functional teams (mechanical, thermal, controls, electronics, systems) to ensure subsystem integration
Perform calculations and simulations to support sizing, performance prediction, and optimization
Support Test Readiness Reviews (TRRs), Failure Review Boards, and design reviews
Implement continuous improvements to increase test efficiency, safety, and reliability
Analyze test data, generate reports, and identify corrective actions
Requirements
Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or a related discipline
2+ years of experience in propulsion, test, or fluid/thermal systems development and testing
Familiarity with liquid or hybrid rocket engine systems, fluid dynamics, thermodynamics, and heat transfer
Experience with instrumentation, sensors, data acquisition, control systems
Proficiency with scripting or programming (Python, MATLAB, etc.)
Ability to read and interpret engineering drawings, P&IDs, and technical specifications
Strong problem-solving, data analysis, and communication skills
Ability to work in multidisciplinary teams and in a fast-paced, evolving environment
Experience with cryogenic fluids, high-pressure systems, or oxidizer/fuel systems
Experience with CAD, simulation tools (CFD, thermodynamics, structural), or propulsion modeling
Familiarity with propulsion test stands, plumbing, valve systems, or turbomachinery
Experience in space, launch vehicle, or high-reliability systems
Experience in formal test planning, instrumentation, and control software
