Job description

What You Will Do

The Eulerian Codes Group (XCP-2) is looking for exceptional candidates to develop and optimize cutting‑edge algorithms for massively parallel multi‑physics codes on heterogeneous high‑performance computing platforms. XCP‑2 staff span a wide range of computational physics disciplines including software engineering, numerical fluid and solid mechanics, materials science, radiation hydrodynamics, plasma physics, turbulence, magnetohydrodynamics, high explosives, nuclear physics and engineering, and neutral and charged particle transport. The duties of our well‑compensated professionals include research and development of applied physics and engineering models, the implementation of these methods into production codes using excellent software development practices, the testing and validation of these methods, and the education and support of users as they adopt these methods.

What You Need

Minimum Job Requirements

Technical Knowledge

For this role you must have demonstrated professional knowledge in software modernization and performance optimization.

High Performance Computing

Candidate will require demonstrated experience with massively parallel numerical development and simulation, and experience deploying numerical algorithms to heterogeneous computing architectures.

Software Engineering & Design

You will need to have recognized proficiency with modern C++. Applicants with experience in Fortran and C languages and the development of multi‑physics scientific codes, including software engineering practices and user support, will be given preference.

Collaboration

Teamwork is essential to the success of our group. As such you will need to have demonstrated the ability to function effectively in a team environment with a willingness to learn new skills and be flexible in work assignments. This includes exhibiting professional conduct in interactions with co‑workers and supervisors.

Communication

Communication skills are critical in our group. Excellent written and oral communication skills are required.

Clearance

This position requires the ability to obtain a DOE Q Clearance, which typically requires US Citizenship.

Education / Experience

Position requires a Bachelor's degree in a STEM field from an accredited college or university and 2 years of related experience, or an equivalent combination of education and experience directly related to the occupation.

Desired Qualifications

C++ Expertise

Candidates that demonstrate experience in C++ template metaprogramming and compile time programming techniques along with C++ standards knowledge will be given preference.

Mission Focus

Candidates that demonstrate experience with LANL's mission and research environment including impact on programmatic deliverables for the nuclear weapons program will be given preference.

Education

B.S. degree in applied mathematics, physics, engineering or related field. M.S. or Ph.D. may be preferred.

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.

Position Commitment

Regular appointment employees are required to serve a period of continuous service in their current position in order to be eligible to apply for posted jobs throughout the Laboratory. If an employee has not served the time required, they may only apply for Laboratory jobs with the documented approval of their Division Leader. The position commitment for this position is 1 year.

Note to Applicants

• Due to federal restrictions contained in the current National Defense Authorization Act, citizens of the People's Republic of China—including the special administrative regions of Hong Kong and Macau—as well as citizens of the Islamic Republic of Iran, the Democratic People's Republic of Korea (North Korea), and the Russian Federation, who are not Lawful Permanent Residents ("green card" holders) are prohibited from accessing facilities that support the mission, functions, and operations of national security laboratories and nuclear weapons production facilities, which includes Los Alamos National Laboratory.
• Applicants should submit a CV/Resume and cover letter. The cover letter should be composed of a one-page career narrative followed by a bulleted list of the applicant's relevant experience for each requirement.
• Contact: Brandon Smith ([e-mail])

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 leave
• Award‑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.
