Laser Plasma Interaction Computational Physicist

Deploy, configure, and extend existing simulation tools such as WarpX and LPSE to model laser plasma interaction phenomena relevant to Xcimer’s laser architecture.

Develop workflows, simulation setups, post-processing pipelines, and benchmarking methodologies for efficient and repeatable simulation execution.

Lead the design and development of in-house LPI simulation software focused on collisional kinetics and paraxial laser propagation models.

Architect simulation software using modular, extensible, and maintainable scientific software frameworks with strong emphasis on composability and long-term scalability.

Implement and validate core physics models including collisional plasma kinetics, paraxial laser propagation, stimulated Raman scattering (SRS), stimulated Brillouin scattering (SBS), filamentation, and cross-beam energy transfer (CBET).

Perform verification, convergence studies, and benchmarking against existing tools, published results, and experimental data to ensure numerical robustness and model credibility.

Optimize simulation software for high-performance computing environments, including parallelization and scalability across modern compute architectures.

Maintain rigorous software engineering practices including version control, automated testing infrastructure, documentation, and reproducibility standards.

Collaborate cross-functionally with laser architecture, gas optics, radiation hydrodynamics, experimental physics, and other engineering teams to prioritize simulation efforts and integrate modeling outputs into broader system development activities.

Contribute to Xcimer’s long-term computational modeling strategy by identifying opportunities to integrate new physics capabilities and couple simulation domains through shared modular architectures.
