• Strong verbal and written communication skills; ability to work effectively in multidisciplinary teams.
• Rapid understanding of mechanical/structural designs and ability to develop creative solutions to emerging concerns.
• Understanding of Geometric Dimensioning and Tolerancing (GD&T) and its impact on production.
• Computer Aided Design software familiarity, especially Creo and/or Solid Works.
• Experience with Structural and Thermal analysis, including Finite Element Analysis.
• Clear understanding of design and manufacturing optimization principles.
• Knowledge of Designing for Excellence (DFX) engineering practices.
• Experience in manufacturing or production of aerospace or missile systems for government-sponsored programs.
• Ability to work effectively on both small and large development teams, internally and externally, within Sandia.
• Experience creating and understanding product documentation such as design documents, assembly procedures, and Interface Control Documents.
• Experience working in a Design Agent and Production Agent collaborative situation.
• Commitment to ongoing personal and professional development.

Applicants must be able to obtain and maintain a DOE Q‑level security clearance, which requires U.S. citizenship. Background investigation and drug testing will be conducted as part of the hiring process.
