Mesh Generation Postdoc
- Req. Number: IRC140990
- Organization : XCP-4/Continuum Models And Numerical Methods
- City, State: Los Alamos, New Mexico
What You Will Do
Join our world-class team! Now is your chance to make a difference in supporting our national security mission. The XCP-4, Continuum Models and Numerical Methods, group of Los Alamos National Laboratory is seeking qualified candidates for a postdoctoral position researching methods at the intersection of computational geometry, mesh generation and machine learning.
XCP-4 is responsible for the design and implementation of a wide variety of physical models and simulation setup software including high explosive, turbulence, solid dynamics and damage models, and is a leader in the development of numerical methods for hydrodynamics simulations, remap and computational meshes.
The successful candidate will contribute within a collaborative team environment to research, develop, implement, and integrate methods for machine learning aided block structured mesh generation algorithms. The candidate will be part of a multi-disciplinary team that also includes research and development on methods for field remapping, material interface tracking, code-to-code linking, and automated simulation workflows. All the work is done in high performance computing environments with multi-core CPUs and GPUs using UNIX operating systems.
The successful candidate will have strong skills in the domain areas of unstructured and block-structured mesh generation, mesh adaptivity, geometric modeling methods and computational geometry. They will actively participate in team decisions on algorithms and research and collaborate with team members to develop and maintain software; therefore, the ability to work well in a team environment is extremely important, as is the ability to interact with users in an efficient and productive manner.

Directive 206.2 - Employment with Triad requires a favorable decision by NNSA indicating employee is suitable under NNSA Supplemental Directive 206.2. Please note that this requirement applies only to citizens of the United States. Foreign nationals are subject to a similar requirement under DOE Order 142.3A.
Clearance: Q (Position will be cleared to this level). Selected applicants will be subject to a background investigation conducted by or on behalf of the Federal Government, and must meet eligibility requirements* for access to classified matter. This position requires a Q clearance. and obtaining such clearance requires US Citizenship except in extremely rare circumstances. Dependent upon the position, additional authorization to access classified information may be required, which may or may not be available to dual citizens. Receipt of a Q clearance and additional access authorization ultimately is a decision of the Federal Government and not of Triad.
*Eligibility requirements: To obtain a clearance, an individual must be at least 18 years of age; U.S. citizenship is required except in very limited circumstances. See DOE Order 472.2 for additional information.
New-Employment Drug Test: The Laboratory requires successful applicants to complete a new-employment drug test and maintains a substance abuse policy that includes random drug testing. Although New Mexico and other states have legalized the use of marijuana, use and possession of marijuana remain illegal under federal law. A positive drug test for marijuana will result in termination of employment, even if the use was pre-offer.
Internal Applicants: Regular appointment employees who have served the required period of continuous service in their current position are eligible to apply for posted jobs throughout the Laboratory. If an employee has not served the required period of continuous service, they may only apply for Laboratory jobs with the documented approval of their Division Leader. Please refer to Policy Policy P701 for applicant eligibility requirements.
Equal Opportunity: Los Alamos National Laboratory is an equal opportunity employer. All employment practices are based on qualification and merit, without regard to protected categories such as race, color, national origin, ancestry, religion, age, sex, gender identity, sexual orientation, marital status or spousal affiliation, physical or mental disability, medical conditions, pregnancy, status as a protected veteran, genetic information, or citizenship within the limits imposed by federal, state, and local laws and regulations. The Laboratory is also committed to making our workplace accessible to individuals with disabilities and will provide reasonable accommodations, upon request, for individuals to participate in the application and hiring process. To request such an accommodation, please send an email to applyhelp@lanl.gov or call (505)-664-6947 opt. 3.
