  • Own R&D-focused structural design and development supporting vehicle subsystems such as hydraulics, fuel systems, propulsion, and avionics, with an emphasis on rapid prototyping and iteration 
  • Perform first-principles structural and thermal analyses using hand calculations and FEA to inform early design decisions and experimental validation 
  • Execute trade studies across mechanical, fluid, and avionics subsystems focused on performance, mass efficiency, and technical risk reduction 
  • Design, build, and test prototype hardware, owning development from concept through fabrication, integration, and experimental validation 
  • Collaborate closely with manufacturing and test teams to transition prototype concepts toward scalable, production-aware designs 
  • Support hands-on integration, troubleshooting, and test campaigns to quickly iterate and mature hardware 
  • Present technical findings in internal design reviews and contribute to cross-functional and supplier/customer technical discussions 
  • Bachelor’s degree in mechanical engineering, aerospace engineering, or physics 
  • 2+ years of experience in mechanical design, analysis, and experimental testing (internships and significant student project experience qualify), preferably in an R&D or prototype environment 
  • Strong hands-on experience with rapid prototyping, hardware build, and mechanical assembly of complex systems 
  • Solid foundation in engineering fundamentals including statics, dynamics, heat transfer, fluid mechanics, and vibration 
  • Proficiency in CAD (NX preferred), FEA (Ansys preferred), and PLM tools (Teamcenter preferred) 
  • Experience designing and testing hardware in early development environments, with awareness of design-for-manufacturing and production considerations 
  • Familiarity with mechanical testing under vibration, fatigue, shock, vacuum, and thermal loads 
  • Demonstrated ability to collaborate across disciplines (fluids, avionics, manufacturing) to deliver integrated experimental systems 
  • Proven ownership of technically complex projects from concept through test and iteration 
  • The salary range listed for this role is intended as a general guideline. Final compensation will be determined based on a variety of factors, including role scope and responsibilities, relevant experience, education and training, key skills, market data, and business needs.

    At Hermeus, compensation is only one part of our total rewards package. We offer competitive pay, equity, and a range of benefits designed to support our team.
