Job summary

Cowboy Space Corp. is seeking a senior hydrodynamic design engineer to own the rocket turbopump pump flowpath design from concept to test. You will drive efficiency, head-rise, axial thrust, and rotordynamics across operating regimes.

You will collaborate with manufacturing, support hot-fire campaigns, and develop modeling tools for the organization while mentoring engineers on complex turbomachinery challenges in a fast-moving space infrastructure company.

Qualifications

• Bachelor’s degree in Aerospace, Mechanical, or related engineering.
• 12+ years of turbomachinery hydrodynamic or aerodynamic design experience.
• Experience with pump sizing and suction analysis.
• Hands-on experience taking rotating hardware from design through build and test.

Responsibilities

• Own pump primary and secondary flowpath hydrodynamic design from concept through qualification.
• Drive hydrodynamic design for maximum efficiency and suction performance while meeting head-rise and rotordynamic requirements.
• Ensure hardware performs across transients, deep throttle, inlet NPSH, and cycles.
• Lead hydrodynamic analysis (meanline/throughflow, CFD) and validate against test data.
• Define and execute pump test campaigns.
• Work with manufacturing to iterate and resolve fabrication/assembly issues.
• Support hot-fire operations and post-test design iteration improvement.
