Cap-Exempt H-1B Position — No lottery required
**What You Will Do** Sigma Division is seeking postdoctoral candidates to develop and apply computational models for manufacturing process development, optimization, materials compatibility, and lifetime prediction. This position will support a broad range of metals and materials processing efforts, with a primary emphasis on casting, heat treatment, thermal-mechanical distortion, and process-structure-property relationships. The successful candidate will work with a mentor and interdisciplinary teams of scientists, engineers, technicians, and technologists to build predictive models, validate those models against experimental data, and translate results into actionable guidance for Los Alamos National Laboratory mission programs. The Sigma Complex is a unique prototyping and fabrication facility that provides materials, components, manufacturing science, and process development to Los Alamos experimental programs. Sigma Division works across a wide materials space, including metal alloys, ceramics, composites, and unconventional materials, and supports national security missions through research, development, and applied manufacturing capabilities. Modeling efforts may include, but are not limited to: - Metal casting, solidification dynamics, and heat-transfer-driven process behavior - Casting and heat-treatment distortion, residual stress, and thermal-mechanical deformation - Mass transfer, fluid flow, gas-solid interactions, and diffusion modeling - Heat treatment response, microstructure evolution, thermodynamics, and kinetics - Electrochemical forming, etching, corrosion, and related materials compatibility phenomena - Coupling of computational simulation with experimental process data for model validation and process optimization Specific projects and processes will be shaped by the candidate's expertise and interests, mission needs within the team, and available funding. The postdoctoral researcher will be expected to help guide the technical direction of the
