Job Description
: We are seeking a Postdoctoral Appointee to develop models and design computational tools to simulate microstructural evolution during advanced manufacturing processes for ceramics and metals. Reponsibilities include, but are not limited to: + Developing models and codes to simulate microstructural evolution during additive and advanced manufacturing of ceramics and metal, particularly sintering of ceramic powders
Required:
+ Ph.D. in Materials Science, Physics or related Engineering discipline (e.g. materials, chemistry, mechanical, etc.) received within the last 5 years + At least three years' high-level experience in scientific computer programming for massively parallel computing clusters + Experience with using, developing, and programming multi-physics microstructural evolution models particularly, Potts and phase-field models + Ability to obtain and maintain a Department of Energy security clearance
Desired:
+ Experience with using, developing, and programming discrete simulation methods such Potts and cellular automata, and continuum thermodynamic methods such as phase-field + Experience with using molecular dynamics to simulate sintering of powder particles + Knowledge of materials processing, especially powder processing and experience in modeling microstructural evolution during such processes + Knowledge of computational modeling and simulation, including mathematical modeling and solution of coupled systems of partial differential equations (PDEs) + Strong verbal and written communication skills and an ability to interact well with fellow technical workers of diverse technical backgrounds + Candidates must be able to publish and to present cutting edge technical work at technical conferences, and have a proven publication track record + Knowledge of materials mechanics and experience in coupling mechanics with microstructural evolution models + Experience with the SPPARKS software package (http://spparks.sandia.gov), use and application of FFT methods + Experience with code verification and modern software quality practices
Department Description:
The Multiscale Sciences Department develops advanced materials simulation capabilities at scales ranging from electronic and atomistic scales to the continuum engineering scale that utilize high-performance computational methods to solve currently intractable problems of national importance. The department is involved in national security and nuclear energy modeling and simulation initiatives. The department also leads efforts to develop peridynamics and non-local gradient free methods for solid mechanics applications involving fracture, failure, and fragmentation.

Security Clearance:
Position requires a Department of Energy (DOE) granted Q-level security clearance. Sandia is required by DOE directive to conduct a pre-employment background review that includes personal reference checks, law enforcement record and credit checks, and employment and education verifications. Applicants for employment must be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. 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 the DOE, rendering the inability to perform the duties assigned and resulting in termination of employment.
EEO Statement:
Equal opportunity employer/Disability/Vet/GLBT : This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia's discretion up to five additional years. The PhD must have been conferred within five years prior to employment. Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance. |
