About IRPI

IRPI is pioneering the hardware that sustains life and enables exploration beyond Earth. Our team develops flight systems for spacecraft, habitats, and suits—covering everything from CO₂ removal and air revitalization to hydroponics, sample preparation, waste management, and fire safety. We design condensing heat exchangers, phase separation and filtration devices, propellant management systems, Lunar lander hardware, space station hardware, and advanced suit subsystems.

What sets IRPI apart is the way we unite research, mechanical design, and fluid / thermal engineering to deliver robust solutions that are rapidly prototyped, tested, and made flight-ready. We thrive on turning bold ideas into hardware that expands the boundaries of human presence in space.

Your Mission

As a Senior Mechanical Engineer , you will own the development of advanced spaceflight hardware—from concept through qualification. You’ll take technical leadership on key projects, mentor early-career engineers, and collaborate directly with NASA and commercial partners to deliver systems that sustain human life beyond Earth.

Your immediate focus will be a novel additively manufactured condensing heat exchanger for low-gravity applications , while also contributing across IRPI’s portfolio of thermal and fluid systems. This role is ideal for an engineer with deep mechanical / thermal / fluid expertise who thrives in a hands-on, fast-paced environment and is ready to deliver hardware that will be integrated into spacecraft systems.

Key Responsibilities

• Lead the design, analysis, and prototyping of technologies and subsystems for spacecraft and life-support applications.
• Own R&D or subsystem development across the full lifecycle : analysis, CAD, computation, prototyping, assembly, test, and qualification.
• Develop and maintain engineering documentation, including test plans, design reviews, and compliance materials.
• Plan and execute validation campaigns, including instrumentation setup, data collection, and root-cause analysis.
• Interface directly with NASA program managers, commercial space operators, and suppliers, among others.
• Mentor and review the work of junior and mid-level engineers, setting high standards in design and testing.
• Contribute technical expertise to proposal, projects, and commercial development programs.
• Shape internal best practices for mechanical design, analysis, and testing of flight hardware.
