AI Summary

Mechanical Engineer responsible for designing, building, and testing aerostructure components from concept to validated prototype, including integration with subsystems and rapid iteration.

About this role

Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.

We are seeking a Mid-Career Mechanical Engineer to support the design, build, and test of next-generation aircraft aerostructures, including fuselage, empennage, control surfaces, and landing gear systems. This role is hands-on and execution-oriented, with responsibility for taking hardware from concept through detailed design, fabrication support, and test validation.

Responsibilities

  • 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

    • Basic Qualifications

  • 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

    • Preferred Skills

  • 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

    • Additional Requirements

  • Willingness to work extended hours and weekends as needed to support critical development milestones
  • Willingness to travel up to 25% of the time
