Directed by Antoine Georges and co-directed by Andrew Millis, the Center for Computational Quantum Physics (CCQ) is a leading international center for the study of equilibrium and non-equilibrium many-body quantum systems, with applications to condensed matter physics, materials science, chemistry and related fields. The development of the concepts, algorithms and code libraries needed to advance the field is fundamental to the work of the center. Research projects currently pursued at CCQ cover a broad range of methods and interest, see:

CCQ currently comprises more than 40 scientists at various career stages from recent Ph.D.s through senior scientists, also including data scientists, support staff and scientific visitors, and is planning to grow to 50+. The institute has a vigorous visitor and workshop programs and strong interactions with scientists from neighboring institutions.

The CCQ seeks a data scientist or associate data scientist with a background in computational physics/chemistry methods and software development. Depending on experience and qualification, the position may be at the associate data scientist or data scientist level. This full-time position offers an exceptional long-term career opportunity at the interface of science and computing, with flexibility to be immersed in frontier scientific research while focusing on computing, algorithms, and technical support.

The occupant of this position will report to a senior research scientist at CCQ and will be responsible for developing the core library and algorithms for a CCQ software suite for quantum Monte Carlo methods, featuring auxiliary-field and related approaches for both model systems and real materials. The position also supports the associated scientific community by creating documentation, responding to user questions, and addressing bug reports. This position may be expected to: provide training through mentoring junior scientists; giving lectures and tutorials at the Flatiron Institute; and external activities such as summer schools. The scientific output of this position also includes publications produced in collaboration with scientists at the Flatiron Institute and elsewhere. Interactions with staff across the Flatiron Institute including domain scientists, data scientists, and the scientific computing core provide unparalleled opportunities for professional development.
