Job Information

Los Alamos National Laboratory Post-Master's Researcher In Monte Carlo Particle Transport in Los Alamos, New Mexico

What You Will Do

You will perform research inthe area of Monte Carlo Particle Transport in the Monte Carlo Codes group (XCP-3). We are looking for candidates to performresearch in the areas of criticality safety, non-analog variance reductionmethods, and Monte Carlo transport on advanced computing hardware (such asGPUs).

XCP-3 provides the Monte Carlo particle transport simulation capability needed to accurately predict the interaction of radiation with matter. Our work supports a variety of Laboratory missions, including stockpile stewardship, nonproliferation, threat reduction,and energy and environmental sciences. We deliver technology, methods, production quality codes, and training to sponsors, primarily U.S. federal agencies, through research, development, and maintenance of high-quality software and documentation. Our predictive capability is the nation’s foremost predictive tool for nuclear criticality safety simulations and plays a central role in tying nuclear weapon simulations to the nuclear test database.

In this role you will perform research and development to improve Monte Carlo particle transport simulationin areas support the national-security programs and mission of the Laboratory. You will be expected to develop methods in the group’s production Monte Carlo particle transport codes, which include the Fortran code MCNP and C++ code MCATK.

What You Need

Minimum Job Requirements:

Scientific Background

You must have advanced knowledge (M.S. level) in one or more of the following technical areas: Monte Carlo radiation transport theory and modelling, computational parallelism, GPU programming.


Forthis role you will need proficiency in either Fortran, Python, or C++.


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

Education/Experience : Position requires an advanced degree (Master’s level) in a STEM field from an accredited college and university. Preference will be given to those with a M.S. in Nuclear Engineering, Computer Science, Physics, or Applied Mathematics, completed within the last five years or soon to be completed.

Desired Qualifications:

Additional Simulation and Software

It would be great if you had experience in performing modeling with radiation transport simulation codes (e.g. MCNP, GEANT, OPENMC, PARTISN, etc.) and a record of achievement in Monte Carlo radiation transport (theory, simulation, code development).

In addition, it would be helpfulif you had experience with modern software development techniques, GPU programming, and computational parallelism (MPI, OpenMP, C++Threads, GPU parallelism).

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
