This position requires access to export-controlled technology. Only U.S. citizens or nationals are eligible. Applications will be accepted on an ongoing basis until the requisition is closed.

IRPI develops advanced space-exploration hardware for lunar, Martian, and low-Earth-orbit missions-spanning propellant management, hydroponics, life-science lab tools, heat exchangers, suit subsystems, and waste-management devices. We transform ideas into qualified flight hardware through rapid analysis, design, prototyping, and testing. If you are a mechanically minded engineer who loves turning bold concepts into real space systems, we want to meet you.
Your Mission

Join a fast-moving, cross-disciplinary team that turns advanced concepts into space-qualified hardware. As an entry-level Mechanical Engineer, you will learn from senior engineers while contributing directly to design, analysis, prototyping, and testing of flight-ready components for low-Earth-orbit, lunar, and Martian missions.
Key Responsibilities

Design Support:

• Assist senior engineers with layouts and trade studies for mechanical, thermal, and fluid systems.
• Contribute ideas during whiteboard sessions and design reviews.

Model & Document

• Build and revise SolidWorks parts, assemblies, and detailed drawings.
• Maintain bills of materials and configuration control.

Prototype & Build

• Operate additive manufacturing equipment, basic CNC, and shop tools to fabricate prototypes and fixtures.
• Assemble test articles and assist in flight-hardware builds.

Experiment & Validate

• Instrument hardware, execute test procedures, and collect data for a variety of fluid-thermal systems.
• Troubleshoot test setups and document deviations.

Data Reduction

• Process test data using Excel, MATLAB, or Python; generate clear plots and engineering conclusions.

Collaboration & Growth

• Work closely with multidisciplinary IRPI teams, NASA partners, and suppliers.
• Seek mentorship, embrace feedback, and contribute to a culture of continuous improvement and high integrity.

This role is ideal for early-career engineers who are hands-on, have a strong work ethic, are curious, and eager to develop full-lifecycle hardware skills while supporting real space missions.

Requirements
Minimum Qualifications

• B.S. in Mechanical Engineering (or closely related field)

• Solid grasp of thermodynamics, heat-transfer, fluid mechanics, and strength of materials.

• Proficiency in SolidWorks for parts, assemblies, and detailed drawings (or equivalent 3D CAD)
• Demonstrated hands-on aptitude-prototype fabrication, test-rig assembly, and use of common shop tools
• Clear, concise technical writing and verbal communication skills

Preferred Qualifications

• M.S. in Mechanical or Aerospace Engineering with a research/design focus
• 1-2 years professional experience gained through internships, co-ops, senior projects, or research assistantships
• Working knowledge of FEA/CFD and data-analysis scripting in MATLAB or Python
• Experience with test instrumentation and data acquisition (e.g., LabVIEW)
• Familiarity with additive manufacturing and CAM workflows
• Exposure to aerospace qualification standards (NASA-STD-5001, MIL-STD-1540, or similar)

Benefits
Compensation & Perks

• Base salary: $78,000 - $95,000 DOE
• Medical and Dental Insurance
• Retirement Plan Contributions
• Paid vacation, sick leave, and U.S. holidays
• Paid parental leave
