We are seeking a highly skilled Mechanical Engineer to support the development of next‑generation munition and UAV-integrated systems within a fast‑paced defense engineering environment.

This role is ideal for candidates who enjoy owning the full mechanical design lifecycle — from concept development and CAD design through prototyping, testing, and production transfer.

• Design munition housings, internal structures, and arming mechanisms in CAD
• Develop mechanical safety architectures with hardware and software teams
• Define materials, tolerances, finishes, and fasteners for rugged environments
• Build and iterate prototypes using 3D printing and CNC methods
• Execute mechanical qualification testing including drop, shock, vibration, and environmental testing
• Manage BOM, weight distribution, and center‑of‑gravity calculations
• Collaborate closely with multidisciplinary engineering teams on integration activities

• 5+ years of experience designing rugged mechanical assemblies in industries such as:
  • Defense
  • Aerospace
  • UAV Systems
  • Automotive
  • Similar regulated environments
• Strong proficiency with parametric CAD tools such as:
  • Solid Works
  • Creo
  • Fusion 360
  • NX
  • Onshape
• Experience creating manufacturing‑ready drawings including GD&T and tolerance stack‑ups
• Hands‑on prototyping experience with FDM/SLA printers, machining, mills, and lathes
• Strong understanding of mechanical failure modes and product reliability
• Strong written and verbal English communication skills

• Experience with safety & arming mechanisms or rugged defense systems
• Familiarity with MIL‑STD‑810 or related environmental testing standards
• Experience with FEA/structural simulation tools
• Background in injection molding or metal‑casting DFM
• UAV/FPV integration experience is highly preferred

Candidates must be comfortable completing an initial 1‑month onsite training period in Kearneysville, WV, before relocating back to their selected work location.
