Job Title Climate, Ocean & Sea-Ice Modeling (COSIM) Scientist (Scientist 3)
Location Los Alamos, NM, US
Organization Name T-3 / Fluid Dynamics & Solid Mechanics

What You Will Do

Los Alamos National Laboratory is a multidisciplinary research institution engaged in science and engineering on behalf of national security. This staff scientist position is within the Theoretical Division in the Climate, Ocean and Sea-Ice Modeling (COSIM) Team, which develops advanced ocean and ice models for the study of climate, climate change, and its impacts on regions and societal assets throughout the globe.

The COSIM team seeks a staff scientist to work on a broad range of activities related to sea-level rise, particularly as driven by the interaction of the Antarctic ocean and land-ice system. We seek expertise in computational physics, high-performance computing, and analyses of the coupled ocean-land ice system. In terms of computational physics, we seek research talents for the development of advanced algorithms to improve the fidelity, performance and portability of global ocean and land-ice models with a focus toward high-resolution, grand-challenge scale coupled simulations. With respect to simulation analyses we encourage research that lead to improved description, fidelity and understanding of high-resolution, coupled, ocean-and-land ice system dynamics. Our models are components of the newly developed U.S. Department of Energy climate model, the Accelerated Climate Model for Energy (ACME ). A particular focus of ACME is fully-coupled, global, high-resolution simulations of the Earth system. Within this broad activity, the focus of Los Alamos National Laboratory is the development of a modeling system capability to produce probabilistic estimates of sea-level rise.

The successful candidate will be required to:

  • Contribute to the completion of milestones related to coupled ocean-land ice system modeling.

  • Develop solutions to a wide range of complex computational physics problems by using new techniques and unconventional methods, particular for overcoming challenges related to the dynamic coupling of ocean-and-land ice models.

  • Report on completed work in technical reports, peer reviewed papers, and presentations.

  • Lead technical decision-making and direction at the project or team level.

  • Coordinate the work of others and serve as a role model for creative technical leadership within the team.

What You Need

Minimum Job Requirements:


  • Demonstrated scientific excellence as evidenced by submission and publication in refereed journals.

  • Demonstrated ability to work both independently and collaboratively with other project members to create or improve numerical models, and the ability to analyze and interpret climate model simulation data. 

  • Experience and knowledge of computational physics and/or climate modeling.

  • Demonstrated experience and success in proposal writing, project management and mentoring. 

Desired Skills:

  • Experience in construction, validation and application of coupled ocean-land ice models.

  • Experience with the ACME, MPAS-Ocean and/or MPAS-Land Ice modeling system is advantageous.

  • Experience or desire to work on community-based model evaluation activities related to the testing and fidelity of coupled ocean-land ice simulations.

  • Experience with the development, verification and validation of complex physical simulations is advantageous.

  • Expertise in current or emerging computer programming in languages compatible with high-performance computing (e.g. Fortran90, C, C++, Legion, Kokkos); expertise in shell scripting and/or data-analysis languages (e.g. Python, Matlab, R). 


A Ph.D. plus five or more years of experience in geophysics, fluid dynamics, solid mechanics, climate modeling, computational science, physics, applied mathematics, or a closely related field.
