Hermeus is a aircraft manufacturer focused on rapid design, build, and test of high-Mach and hypersonic aircraft.
The Role
Design and analyze mechanical and structural subsystems for high-speed aircraft, perform hand calculations and FEA, lead trade studies, collaborate across disciplines, own hardware from concept through test, and present technical content in reviews.
Summary Generated by Built In
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

Basic Qualifications

  • 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

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.

What We Do

Hermeus is a high-speed aircraft manufacturer focused on the rapid design, build, and test of high-Mach and hypersonic aircraft for the national interest. Working directly with the Department of Defense, Hermeus delivers capabilities that will ensure that our nation, and our allies, maintain an asymmetric advantage over any and all potential adversaries. Utilizing an integrated, hardware-rich, iterative development approach to aircraft design and build, Hermeus aims to deliver advanced air power at a pace not seen in the U.S. since the 1950s. Hermeus’ current Quarterhorse Program is actively unlocking unmanned high-speed flight. One program, four aircraft – each purpose-built to unlock a specific technical challenge, advance learnings, and incrementally de-risk critical technology in the pursuit of hypersonic aircraft. Today, Hermeus is building its second Quarterhorse vehicle, Mk 2, after having designed, built, and flight tested its predecessor, Mk 1, in 18 months. Capable of reaching speeds of Mach 3+, Quarterhorse Mk 2 will be the fastest uncrewed military aircraft in service for national defense. The final iteration of Quarterhorse, Mk 4, will be capable of transitioning from turbofan to ramjet mode utilizing a Hermeus-developed turbine-based combined cycle (TBCC) propulsion system to achieve sustained speeds of Mach 5+. Hermeus' approach of build-fly-build lays the groundwork for unlocking hypersonic flight at a pace and cost previously deemed impossible. America needs fast planes fast – and Hermeus is delivering them.

Why Work With Us

We prioritize hardware and people. Cutting-edge technology is only made possible by bringing together a world-class team. At Hermeus, you will be challenged – but also empowered. We encourage calculated risks taking and learning from our mistakes. Iteration is the name of the game.
