The Role
This role involves leading project planning, hardware delivery, manufacturing processes, and integration testing for aerospace products.
Summary Generated by Built In
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.

This role sits at the intersection of engineering design, manufacturing, integration and test for flight vehicles. You'll be embedded with design and production teams, owning everything from hardware design, tooling, testing and flight readiness to process development and vehicle assembly. We are hiring entry-level through senior-level. 

Responsibilities

  • Lead detailed project planning and drive hardware delivery on aggressive timelines. 
  • Collaborate directly with high level design concepts turning them into detailed designs including final geometry, material selection and DFM. 
  • Drive the transition from prototype to production for complex aerospace assemblies. 
  • Ruthlessly question process complexity—delete parts, eliminate waste, simplify flow. 
  • Design and implement full-stack build processes—factory layout, tooling, test flow, and vehicle integration. 
  • Develop and run test procedures for flight hardware. 
  • Serve as a force multiplier across production, test, and design teams. 

Basic Qualifications

  • Strong engineering first principles. 
  • Bachelor's degree in mechanical, aerospace, manufacturing, or related engineering field. 
  • Hands-on experience with physical hardware (internships, labs, project teams all count). 
  • Proven ability to design, build, break, and iterate quickly. 
  • Comfort with CAD, test equipment, hand tools. 
  • Familiarity with manufacturing processes (machining, welding, forming, etc.) and GD&T fundamentals. 

Preferred Skills and Experience

  • Designed and released flight hardware. 
  • Familiarity with Siemens Teamcenter and NX. 
  • Leadership experience on project teams or in mentorship roles. 
  • You’ve built something that’s flown, broken, or both. 
  • Experience standing up production lines or test infrastructure in a fast-paced environment. 

Additional Requirements

  • Must be available to work extended hours and/or weekends as needed to support critical milestones. 
  • Must be willing to travel to test sites, other Hermeus offices, and partner locations as needed (up to 25% travel) 

U.S. EXPORT CONTROL COMPLIANCE STATUS 
The person hired will have access to information and items subject to U.S. export controls, and therefore, must either be a “U.S. person” as defined by 22 C.F.R. § 120.62 or otherwise eligible for deemed export licensing. US persons include U.S. citizens, U.S. nationals, lawful permanent residents (green card holders), and asylees and refugees with such status granted, not pending.

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.
