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.

Requirements

• Strong engineering first principles.
• Bachelor's degree in mechanical, aerospace, manufacturing, or related engineering field.
• 1+ years of 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 releasedflight 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.
• 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)
