About Our Team:

The Soft Material Sciences R&D Department conducts applied research on the structure and behavior of complex engineered material systems exhibiting coupled physical processes that span multiple length and time scales. This research encompasses theoretical/computational and experimental methods and analysis of energetic (propellants, explosives, pyrotechnics) and soft materials (complex fluids, aerosols, polymers, powders and particles) and multiphase/composite systems. We support partner organizations in scientific assessments for design, production, performance and safety of material systems (e.g., critical components) as well as in the development and manufacturing of novel materials for high consequence, extreme environment applications.

Posting Duration:

This posting will be open for application submissions for a minimum of three (3) calendar days, including the 'posting date'. Sandia reserves the right to extend the posting date at any time.

Security Clearance:

Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education…
