Job Description


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\.


We are seeking an R&D postdoc to join our multi\-disciplinary team of mathematicians, engineers and computer scientists developing algorithms and software in combinatorial scientific computing to meet the challenges posed by next\-generation high\-performance computing hardware\. Increasingly heterogeneous architectures, reduced on\-node memory bandwidth, and ever\-growing demands for extreme levels of concurrency are driving the need for novel portable and highly scalable algorithms\. This position offers the opportunity for highly motivated and enthusiastic researchers to work in a collaborative environment to meet national computing needs in energy, climate, and national security\.

On any given day, you may be called on to:

+ Conduct innovative research and software development in high\-performance graph and hypergraph algorithms for physics\-based and data\-centric applications
+ Execute and optimize your software on state\-of\-the\-art testbed computers and supercomputers at Sandia and other DOE facilities
+ Collaborate with engineers, mathematicians and scientists across many disciplines
+ Publish in journals and conferences, and present at national and international venues
+ Develop, improve, and support Trilinos, a major Sandia software base for research, development and deployment of new algorithms


+ PhD, conferred within 5 years prior to employment, in computer science, mathematics, or related engineering or science discipline
+ Experience with graph/hypergraph algorithms, sparse linear algebra kernels and/or other combinatorial algorithms
+ Experience in large\-scale parallel programming
+ Experience with object\-oriented programming in C\+\+
+ Technical publications in HPC conferences and journals, and/or released software used by applications


+ Experience in graph partitioning or load balancing
+ Experience in task mapping for parallel computing
+ Experience in performance\-portable parallel programming \(e\.g\. Kokkos\)
+ Experience in architecture\-aware algorithm development and implementation for GPU and Xeon Phi architectures
+ Experience developing or working with Trilinos
+ Experience developing and deploying robust parallel software
+ Experience working in collaborative software teams

Security Clearance:

This position does not currently require a Department of Energy \(DOE\)\-granted security clearance\.

Sandia will conduct a pre\-employment drug testing, and a pre\-employment background review that includes personal reference checks, law enforcement record checks, and employment and education verifications\. Further, employees in New Mexico must pass a U\.S\. Air Force background screen for access to the work site\. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, rendering the inability to perform the duties assigned and resulting in termination of employment\.

If hired without a clearance, and one subsequently becomes required or you bid on positions that require a DOE\-granted security clearance, a pre\-processing background review that includes personal reference checks, law enforcement record and credit checks, and employment and education verifications may be conducted prior to a required federal background investigation\. Applicants for DOE\-granted security clearances must be U\.S\. citizens and be able to obtain and maintain the appropriate DOE security clearance as required for the position\.
