About the role

Mechanical Design Engineer responsible for establishing a complete development, testing, and production capability for warheads and SAFing devices, driving product design across munition systems including mechanical housings, casings, warhead assemblies, and mechanisms for autonomous defense platforms.

Responsibilities

  • CAD Design & Drafting: Lead mechanical design and detailed drafting for warhead assemblies, housings, and fuzing mechanisms using industry best practices.
  • Product Data & Configuration Management: Manage product data (PDM) and configuration across design cycles, maintaining clean engineering data packs and release documentation.
  • Prototype Assembly & Verification: Assemble mechanical prototypes, verify fit/function, and define assembly procedures for mission-representative environments.
  • Interface & Systems Integration: Own interface management with higher-level systems, drafting ICDs, MSDS, and packaging/marking specifications.
  • Thermal & Mechanical Analysis: Perform fundamental stress, thermal, and physical analysis based on operational requirements, including exposure, mechanical shock, and vibration.
  • R&D & Material Sourcing: Conduct research into advanced warheads and SAFing technologies; engage with suppliers to manage materials sourcing, non-conformances, and change requests.
  • Cross-Team Collaboration: Work with energetics, simulation and analysis, electronics, and flight test teams to support hardware testing regimes and rapid iteration.

Qualifications

  • Proven background in mechanical design drafting for military applications, ideally involving warheads, SAFing, or fuzing systems.
  • Expertise with production tooling and manufacturing processes (machining, pressing, stamping, milling, forging, casting, injection molding).
  • Solid understanding of military specifications, GD&T standards (ASME/ISO), material compatibility, and environmental survivability.
  • Hands-on experience running environmental and stress analyses (mechanical shock, vibration, thermal) on military systems.
  • Proficiency with Product Data Management (PDM) and configuration control workflows (e.g., Siemens Teamcenter).
  • Detail-oriented with exceptional documentation, organizational, and drafting standards skills.
  • Strong communication and collaborative skills, with a proactive approach to solving complex engineering challenges in a fast-paced environment.
