Senior Mechanical Engineer, Space Systems

IRPI • Wilsonville, OR

3d

About The Position

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 the most demanding 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.

Requirements

• B.S. or M.S. in Mechanical, Aerospace, or related engineering field.
• 7+ years of experience designing, analyzing, and testing mechanical and thermal-fluid systems; M.S. counts as 1 year toward this requirement.
• Demonstrated technical depth: you are the person who has solved hard problems, not just contributed to the team that did.
• Proven end-to-end ownership of subsystems through design, analysis, test, and — ideally — flight or qualification.
• Expert-level proficiency in SolidWorks or equivalent CAD, including manufacturing drawings, GD&T, and tolerance analysis.
• Hands-on experience with prototyping, machining, or additive manufacturing; you build and test, not just simulate.
• Strong command of test instrumentation, data acquisition, and analysis (Excel, MATLAB, or Python).
• Excellent written and verbal communication; able to present technical conclusions clearly to internal and external stakeholders.
• U.S. citizenship or nationality (required for export-controlled work).

Nice To Haves

• Experience at a small space company, startup, or small-team R&D environment.
• Direct experience with NASA program lifecycles, formal design reviews (PDR/CDR), or flight qualification processes.
• Familiarity with aerospace standards (NASA-STD-5001, MIL-STD-1540, or similar).
• Track record of mentoring engineers or leading small technical efforts.

Responsibilities

• Own the design, analysis, and test of complex mechanical, thermal, and fluid subsystems across multiple active projects.
• Mentor mid-level and early-career engineers: review their designs, analyses, and test plans; give direct, constructive feedback; and help them develop sound engineering judgment.
• Balance hands-on problem-solving with program-level judgment — know when a detail warrants a deep dive and when it's good enough to move forward.
• Lead trade studies, develop design concepts, and drive technical decisions through PDR, CDR, and into flight.
• Produce and review detailed SolidWorks models, assemblies, and drawings; enforce configuration control discipline across the team.
• Author and maintain bills of materials for prototype and flight builds; coordinate with suppliers and fabricators.
• Plan and lead test campaigns: design test setups, write procedures, execute tests, and deliver clear engineering conclusions from the data.
• Diagnose and resolve complex design, analysis, or test anomalies — and document your reasoning rigorously.
• Serve as a technical point of contact with NASA and commercial partners during reviews and integration activities.
• Contribute to IRPI's culture of continuous improvement, accountability, and technical excellence.

Benefits

• Comprehensive medical and dental insurance for employees and families
• Employer contributions to help you build long-term security
• Generous paid vacation, sick leave, and holiday schedule
• Paid parental leave and flexibility to support work-life balance
• Annual bonus opportunities tied to company and individual success
• Hands-on experience with flight hardware, close collaboration with principal engineers, and the opportunity to shape technical direction on cutting-edge space programs
