Job Description

This posting will be open for application submissions for a minimum of seven (7) calendar days, including the ‘posting date’. Sandia reserves the right to extend the posting date at any time. : Sandia demonstrates its commitment to public safety in the national interest by requiring that all new hires attest to their vaccination status before commencing employment. The requirement also applies to those who are telecommuting and working virtually. Any concerns about the ability to meet this requirement should be directed to HR Solutions at (505) 284-4700. : Join a dynamic team that solves significant issues for our nation’s security! You could be the highly motivated Postdoctoral Appointee we are seeking to conduct research on emerging plasma simulation methods and applications! Ongoing modeling and code development efforts are part of state-of-the-art massively parallel Particle-In-Cell code. This Sandia proprietary code is used to model plasma generation through vacuum arc breakdown and the simulation of transient plasma generation and transport under non-equilibrium conditions using advanced computer science algorithms to accommodate large variations in spatial/temporal scales and densities. Dynamic plasma-surface interactions and circuit coupling, including integration with other code suites are of increasing interest. You can expect a dynamic team environment where physics models and code development occur in unison with validation and verification efforts as well as direct application to real world problems relevant to Sandia’s mission! Responsibilities include, but are not limited to: + Advance the plasma simulation capability on tasks which leverage candidate’s skills and experience. + Support code development and implementation in a workflow that is tightly coupled to verification and validation efforts. + Participate in theoretical and/or computational research to further scientific knowledge on plasma generation, transient plasma behavior, and plasma transport under non-equilibrium conditions. + Participate in peer review of research through presentation and publication of results within Sandia and the broader computational plasma physics community. + Collaborate with internal and external plasma physicists to understand modeling needs and priorities as well as emerging plasma simulation techniques.

+ Ph.D. in Physics, Electrical Engineering, Mechanical Engineering, Aerospace Engineering, Chemical Engineering, Computer Science, Applied Mathematics or other related science or engineering field shall be completed before starting this position. + Experience with theoretical and/or computational plasma physics + Record of peer-reviewed publications and presentations within the plasma science community + Ability to obtain and maintain a DOE Q clearance

+ Familiarity with the following: + Computational simulation methods for modeling plasma flow, generation and transport + Particle-based PIC or direct simulation Monte Carlo (DSMC) and/or particle-fluid (hybrid) codes + Dynamic plasma-surface interactions such as surface erosion, re-deposition and non-equilibrium effects + Code development in a modern programming language, particularly C or C+ + + Integration of disparate codes, such as coupling between plasma and circuit modeling codes or plasma and mechanical/thermal codes + Stability analysis and experimental plasma physics + Linux OS, HPC platforms, and post-processing/data analysis + Ability to work with multi-disciplinary teams

Department Description:

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 verifications. Applicants for employment need to be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted. Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.
