• Contribute to the design and integration of advanced algorithms in one or more of the following areas, with opportunities to take on increasing responsibility over time:

  • Solvers and preconditioners for sparse structured linear systems

  • Solvers and preconditioners for sparse structured linear and nonlinear eigen systems

  • Tensor algebraic problems

  • Bayesian statistical methods, leading to robust and scalable UQ methods

  • Linear algebra and tensor algorithms for quantum computing

  • AI/ML algorithms for HPC code development

  • Novel algorithms for advancing AI/ML methodology

• Assist with code optimization and integration into Department of Energy (DOE's) applications running on the exascale computer systems with GPU accelerators

We are looking for:

• PhD or equivalent experience in applied mathematics, computer science, or a related field

• Demonstrated experience in developing algebraic solvers

• Proficiency in more than one computer programming language, such as Python, C/C++, CUDA, Fortran

• Knowledge of complexity and performance analysis and advanced data structures

• Knowledge of sparse matrix techniques

• Knowledge of methods for solving linear systems and eigenvalue problems

• Experience of MPI, OpenMP, and other parallel programming models

• Understanding of quantum many-body problem and tensor eigenvalue problem

• Excellent oral and written communication skills

• Ability to conduct independent research

• Ability to collaborate effectively with a multidisciplinary research team

Desired Qualifications:

• Postdoctoral experience in a relevant field

• Experience in programming massively parallel computer platforms
