Flatiron Software Research Fellow, Center for Computational

Astrophysics

• Description
• Applications are invited for postdoctoral positions as Flatiron
• Software Research Fellows (FSRFs) at the Center for Computational
• Astrophysics (CCA). The CCA offers FSRFs the opportunity for
• independent scientific software development and scientific research in
• areas that have strong synergy with the CCA or other centers at the
• Flatiron Institute. The FSRF is distinct from the standard Flatiron
• Research Fellow position in that innovative software development is
• expected to be a core focus and driver of any FSRF's research program.
• The CCA will provide mentorship and career development support to each
• FSRF as well as guidance on trajectories within and outside academia.

• The mission of the Flatiron Institute is to advance scientific
• knowledge through computational methods, including data analysis,
• theory, modeling, and simulation. It currently houses five centers,
• focused on computational astrophysics (CCA), biology (CCB),
• mathematics (CCM), neuroscience (CCN) and quantum physics (CCQ), as
• well as a scientific computing core (SCC) that maintains
• state-of-the-art computing facilities for use by Flatiron scientists,
• and an initiative in computational catalysis (ICC).

• The CCA's particular mission is to create, develop, and disseminate
• computational methods, tools, and frameworks that allow scientists to
• build or analyze big astronomical datasets, and to use computational
• and statistical techniques to understand complex, multi-scale physics
• in astrophysical systems ranging in scales from planets to the
• Universe. Part of this mission is to develop, maintain, and contribute
• to open-source software packages and their communities. Examples of
• software project applications of CCA researchers include fluid
• dynamics and plasma simulations, radiative transfer, N-Body &
• dynamical simulations, GPU & other high-performance computing, machine
• learning models, probabilistic models for data, novel techniques for
• making measurements, visualization tools, and community-oriented
• foundational software tools. For examples of software developed or
• hosted at the CCA, please visit our website:
• https://www.simonsfoundation.org/flatiron/software/?type=39

• Please also visit
• https://www.simonsfoundation.org/flatiron/center-for-computational-astrophysics/
• for a full description of CCA research areas and scientific staff. We
• recommend candidates review our FAQ prior to submitting an
• application.

• Flatiron Software Research Fellows are expected to develop or
• substantially contribute to innovative astronomical software projects
• that enable new or foundational science programs that can be
• independently directed and involve substantial collaboration with
• other members of the CCA or Flatiron Institute. Software projects are
• expected to enable new science and to encourage community engagement
• and use of the resulting tools. FSRFs will be encouraged to build
• their technical skills through engagement and collaboration with
• software engineers and other FSRFs at the CCA, other Flatiron centers,
• and the Flatiron Institute's Scientific Computing Core (SCC). This
• includes attending and/or co-organizing software workshops and
• training hosted both by the CCA and the SCC. In addition to their own
• software development and research, Fellows help build the rich
• scientific community at the CCA and Flatiron Institute by:
• participating in seminars, colloquia, and group meetings; developing
• their software, mathematical, and computational expertise through
• internal educational opportunities; and sharing their knowledge
• through software releases and contributions, scientific publications,
• and/or presentations. Flatiron Software Research Fellows may also have
• the opportunity to mentor and educate graduate and undergraduate
• students through the CCA Pre-Doctoral Program, the CUNY Astrophysics
• Masters Program, the Simons-NSBP Scholars Summer Program, and the
• AstroCom NYC Program. FSRFs are welcome and encouraged to take
• advantage of CCA partnerships with the Simons Observatory, the Terra
• Hunting Experiment, Sloan Digital Sky Survey V, the Laser
• Interferometer Gravitational-Wave Observatory, Gaia, and the NASA
• SPHEREx mission.

• FSRF positions are generally two-year appointments that can be renewed
• for an additional three years, contingent on performance. All Fellows
• receive a research budget and have access to the Flatiron Institute's
• powerful scientific computing resources, including 2 HPC clusters with
• a combined 180,000 cores, 600 GPUs and 60PB of raw storage. FSRFs may
• be eligible for subsidized housing within walking distance of the CCA.
• These positions will be based in our New York City offices, with
• anticipated start dates between late August and early October 2027.

Responsibilities include but are not limited to:

• Developing, implementing, maintaining, and supporting scientific software relevant to astrophysics

• Engaging in astrophysical research using computational and/or theoretical tools

• Assisting in the organization of CCA and Flatiron-wide collaborative activities including seminars, workshops and meetings

• Actively participating in the preparation of manuscripts for publication and presentations at conferences

• Assisting in student mentorship

• Sharing expertise and providing training and guidance to CCA staff and visitors as needed, including participation in the Software Group and periodically running software tutorials
