Mechanical Engineer

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.

Responsibilities

• Structural design supporting vehicle subsystems such as hydraulics, fuel systems, propulsion, and avionics

• Perform structural and thermal analyses using both hand calculations and FEA

• Lead trade studies across mechanical, fluid, and avionics subsystems with an emphasis on mass efficiency, cost, and performance

• Collaborate with manufacturing, supply chain, and test teams to ensure designs are practical, producible, and aligned with program objectives

• Own hardware development from concept through design, fabrication, integration, and test

• Present technical content in internal reviews and represent the team in cross-functional and supplier/customer design reviews

Requirements

• Bachelor’s degree in mechanical engineering, aerospace engineering, or physics

• 1+ years of experience with electromechanical design, analysis, and testing (internships and significant student project experience qualify)

Preferred Skills and Experience

• Hands-on prototyping and mechanical assembly experience for complex systems

• Strong foundation in engineering fundamentals including statics, dynamics, heat transfer, fluid mechanics, vibe

• Proficiency in CAD (NX preferred), FEA (Ansys preferred), and PLM tools (Teamcenter preferred)

• Familiarity with mechanical testing under conditions such as vibration, fatigue, shock, vacuum, and thermal loads

• Experience collaborating across disciplines (e.g., fluids, avionics, manufacturing) to deliver integrated systems

• Demonstrated cradle to grave ownership of technically complex projects

Additional Requirements

• Willingness to travel up to 25% of the time
