Job description

What You Will Do

The Eulerian Codes Group (XCP-2) in the X-Computational Physics (XCP) Division is seeking talented and motivated postdoc candidates. The Eulerian Codes Group is responsible for developing and maintaining large scale, massively parallel multi-physics codes used in national security applications. This appointment will focus on development and implementation of new methods for scalable performance on modern computer architectures. The successful candidate is expected to work in a team environment with computational scientists, theoreticians, and experimentalists, become familiar with production software carpentry practices, and publish results.

What You Need

• A PhD in Physics, Astrophysics, Applied Mathematics, Engineering, or related field
• Solid background in numerical methods
• Proficiency in Fortran, C/C++, or Python
• Strong record of publications
• Strong oral and written communication skills
• Ability to obtain a DOE Q Clearance, which typically requires US Citizenship

Desired Qualifications:

• Experience in modeling highly-coupled physics experiments for compressible flows
• Solid background in numerical methods for solving systems of partial differential equations in fluid dynamics or related fields
• Experience with massively parallel numerical development and simulation
• Experience with deploying numerical algorithms to future computing architectures
• Experience with code development relevant to computational physics

Education

A Ph.D. in Applied Mathematics, Physics, Engineering, Computational Science, or a closely related field completed within the past five years or soon to be completed.

Work Location

The work location for this position is onsite and located in Los Alamos, NM. All work locations are at the discretion of management.

Where You Will Work

Located in beautiful northern New Mexico, Los Alamos National Laboratory (LANL) is a multidisciplinary research institution engaged in strategic science on behalf of national security. Our generous benefits package includes:

• PPO or High Deductible medical insurance with the same large nationwide network
• Dental and vision insurance
• Free basic life and disability insurance
• Paid childbirth and parental leaveAward-winning 401(k) (6% matching plus 3.5% annually)
• Learning opportunities and tuition assistance
• Flexible schedules and time off (PTO and holidays)
• Onsite gyms and wellness programs
• Extensive relocation packages (outside a 50 mile radius)

Additional Details

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. No Clearance: Position does not require a security clearance. Selected candidates will be subject to drug testing and other pre-employment background checks.

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.
