The Princeton University Department of Astrophysical Sciences invites applicants for one or more postdoctoral or more senior research positions in weak lensing cosmology within the Princeton Astronomical Data Group (led by Robert Lupton, Michael Strauss, and Jim Gunn). Join and grow our fast-paced group in the development and commissioning of the software pipelines for the Large Synoptic Survey Telescope (LSST) and the Hyper Suprime-Cam (HSC) instrument on the Subaru Telescope. The department currently plays a leading role in exploiting the HSC survey data, presenting opportunities to become deeply involved in the HSC weak lensing analyses. Additional instrumental efforts of the Astronomical Data Group include the 2400-fiber Prime Focus Spectrograph (PFS) for Subaru, and all members of the department will have the opportunity to join the planned PFS survey team.

The successful candidate(s) will lead the internal validation of components of the science pipelines (e.g., shear estimation, PSF estimation, deblending, coaddition) on weak lensing estimates. As a member of the LSST project team, this role will collaborate closely with other parts of the geographically distributed LSST construction team and with the LSST Dark Energy Science Collaboration. As a member of the Department of Astrophysical Sciences, this role comes with full rights to HSC survey data and an invitation to join the HSC weak lensing collaborations. An ideal candidate would have a research record in shear estimation, PSF modeling, or other image processing algorithms relevant for weak lensing on large imaging surveys, experience in software development with Python or C++, and a collaborative spirit. A Ph.D. in a related field is required.

We are seeking to recruit from as diverse a pool of talent as possible, and endeavor to preserve the Department of Astrophysical Sciences' reputation as a pleasant workplace with a lively and friendly scientific atmosphere which recognizes that technical innovations are an important intellectual contribution to the science produced by major astronomical surveys.

Applicants must apply online at and submit a CV, a brief statement of research interests, and contact information for three references. Applicants should apply by September 1st, 2018, for full consideration, but applications will continue to be accepted until the position is filled. Initial appointment is a one-year term, with the expectation of renewal. This position is subject to the University's background check policy.
