Mechanical Engineer, Space Systems

IRPI is pioneering the hardware that sustains life and enables exploration beyond Earth.

We design and build flight systems for spacecraft, habitats, and suits, advancing systems that manage air, water, waste, and thermal control for human missions. Our portfolio spans CO₂ removal and air revitalization, hydroponics, biological sample processing, waste management, and fire safety, as well as condensing heat exchangers, propellant management devices, lunar lander components, and advanced suit subsystems.

What makes IRPI unique is how we integrate research, design, and fluid-thermal engineering to produce hardware that performs in challenging environments. From early-stage concepts to flight-qualified systems, we transform ideas into tested, mission-ready technology that expands the boundaries of human presence in space.

Your Mission

As a Mechanical Engineer at the mid-level , you’ll take ownership of subsystem design and testing for active NASA and commercial space programs. You’ll work hands-on across the full lifecycle—from concept development, CAD, and analysis through in-house prototyping, test execution, and flight integration. You’ll help drive design decisions, coordinate with partners, and ensure designs mature into reliable, high-performance hardware.

This role is ideal for engineers with at least a few years of experience who are ready to lead discrete efforts, mentor early-career teammates, and deepen their technical expertise while working on real flight projects.

This position requires access to export-controlled technology. Only U.S. citizens or nationals are eligible.

Key Responsibilities

• Lead design and analysis tasks for mechanical, thermal, and fluid systems supporting spaceflight hardware.
• Develop concepts, perform trade studies, and drive design reviews with cross-disciplinary input.
• Create and manage detailed SolidWorks models, assemblies, and drawings under configuration control.
• Generate, maintain, and release bills of materials for prototype and flight builds.
• Oversee and participate in the fabrication and assembly of test articles and flight hardware.
• Design and instrument test setups; execute tests and analyze performance data using Excel, MATLAB, or Python.
• Identify, troubleshoot, and resolve design or test issues with minimal supervision.
• Document results and present clear technical conclusions to internal and external stakeholders.
• Support integration and verification activities with NASA and commercial partners.
• Contribute to IRPI’s culture of continuous improvement, accountability, and technical excellence.

We’re looking for engineers who take pride in craftsmanship, think creatively across disciplines, and thrive in a fast-paced, high-accountability environment.
