Our department provides technical and programmatic leadership in lethality, vulnerability, and threat assessment for national security missions. The department supports the Missile Defense Agency and other DOE and DoD customers by delivering technically defensible, decision-quality analyses for defensive and offensive applications, from endgame lethality through post-intercept outcomes.

Our work focuses on extreme engagement environments, including hypervelocity kinetic impacts, high-explosive shock loading, nuclear blast loading, and high-rate structural response. We use Sandias capabilities in shock physics, advanced solid mechanics, coupled hydro-structural analysis, high-fidelity simulation, and engineering-level assessment tools to evaluate weapon effectiveness, target response, survivability, and lethality/vulnerability criteria. Our work brings together analysts, modelers, experimentalists, systems engineers, and program leads to solve technically challenging problems with direct national security impact.

The department also supports threat engineering efforts by integrating expertise across Sandia, the Intelligence Community, and mission partners to develop comprehensive threat packages for current and emerging threats. These efforts may include computer-aided design/drafting, aero-thermal analysis, trajectory analysis, uncertainty characterization, and other specialized technical areas needed to support robust lethality and threat assessments.

Through this work, our team helps customers and decision-makers better understand current and emerging threats, characterize and bound uncertainty, and make informed decisions about weapon effectiveness, target response, and survivability across a broad range of engagement scenarios.

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.
