What You'll Do:

  • Serving as the senior technical lead and trusted advisor for key aerospace and defense programs.
  • Leading AM strategy, qualification plans, and adoption pathways across complex customer missions.
  • Running technical design reviews, engineering workshops, and program strategy sessions with customer leadership.
  • Translating mission and performance requirements into optimized metal AM solutions that balance cost, risk, and reliability.
  • Developing high-impact proposals, white papers, and technical recommendations for advanced AM applications.
  • Driving implementation of DfAM best practices, simulation-based optimization, and qualification approaches for mission-critical hardware.
  • Working cross-functionally with business development, manufacturing, and quality teams on capture strategies and program execution.
  • Acting as the primary technical interface from concept through qualification and production.
  • Mentoring engineers and elevating the organization's customer-facing AM technical depth.
  • Ensuring compliance with aerospace standards: AS9100D, NADCAP, MIL-SPEC, ITAR, and other regulatory requirements.


What You Need to Bring:

  • Recognized expertise in metal additive manufacturing for aerospace and defense applications.
  • A proven ability to influence design, qualification, and engineering decisions at primes, OEMs, and government agencies.
  • Deep knowledge of LPBF/DMLS, DED, and hybrid AM processes and relevant alloys (Ti, Ni, Al, Cu).
  • Strong background in aerospace materials science, metallurgy, and thermal-mechanical behavior of AM components.
  • Proficiency in CAD (NX preferred), AM simulation tools, and FEA, with the ability to present technical findings clearly.
  • Demonstrated success presenting to executive and non-technical customer stakeholders.
  • Understanding of AS9100D, NADCAP, MMPDS, MIL-SPEC, and aerospace certification and qualification pathways.
  • Leadership skills to mentor and guide engineering teams in both technical execution and customer engagement.
  • Bachelor's degree required (Mechanical, Aerospace, or Materials Engineering).
  • Master's degree preferred.
  • 10+ years in aerospace/defense AM engineering, advanced design, or manufacturing applications.
  • Eligibility to obtain and maintain a DoD SECRET Security Clearance (required for employment).


Benefits:


  • Comprehensive medical, dental, and vision insurance
  • 401(k) retirement plan
  • Dynamic, collaborative culture focused on innovation and professional growth
