As a Mechanical Engineer, this role will join Interlune's engineering team and be responsible for the physical design, development, and implementation of the critical hardware that will make space resource utilization possible. This position would be full time at the Interlune Research lab (IRL) in Houston, TX. Applicants from all industries are welcome, with particular emphasis in complex, multi-disciplinary system development. Familiarity with and prior experience in the space, oil and gas, construction, or mining industry are valuable but not required. Responsibilities: • Drive the detailed mechanical design of vacuum system components and assemblies, including pumps, valves, tubing, and heat exchangers, through all lifecycle phases and demonstrate extreme ownership. • Develop and design mechanical systems to scale from laboratory testing to production. • Conduct analysis for sizing components including hand calcs and FEA. • Apply an understanding of electro-mechanical principles to integrate sensors, instrumentation, controls, and power distribution seamlessly with vacuum hardware. • Lead design reviews as system and subsystem designs are established and refined. • Oversee the procurement, assembly, and integration of mechanical and vacuum system hardware. • Develop and execute test plans to verify and validate system performance from the component level through to fully integrated system tests. • Serve as a key design expert, collaborating with other subsystem teams to ensure seamless hardware integration and meet all mission requirements. Required Qualifications: • B.S. in Aerospace Engineering, Mechanical Engineering, or related technical subject area. • 3+ years of experience in the design of electro-mechanical systems using a CAD software design package (e.g. Solidworks, NX, CATIA, or Creo) and Geometric Dimensioning and Tolerancing (GD&T). • Direct experience designing and troubleshooting hardware for high vacuum systems. • Recent, practical hands-on experience with hardware assembly, integration, and testing. • Familiarity with common manufacturing methods (machining, welding, hand and power tools, etc.). • Ability to operate effectively with minimal direction, maintaining a high attention to detail and aspiration for technical excellence, and have a demonstrated track record of resourcefulness and success from previous work. Desired Qualifications: • M.S. or Ph.D.in Mechanical Engineering, or related technical subject area. • Direct experience designing or operating ultra-high vacuum chambers. • Proficiency with FEA software (e.g., ANSYS Mechanical, NASTRAN, Abaqus) and fluid analysis tools. • Experience programming or configuring control systems (LabVIEW, Python) for vacuum automation. • Functional knowledge of electrical systems, data acquisition (DAQ), sensor integration, and wiring schematics to ensure cohesive electro-mechanical design.
