About this position
Lawrence Livermore National Laboratory (LLNL) is advertising a Postdoctoral Researcher opening in Astronomy & Astrophysics, focused on astrometry, stellar remnants, and microlensing related research using NASA’s Nancy Grace Roman Space Telescope. The role sits in the Astronomy Astrophysics & Analytics Group within the Physics Division and involves building an astrometric detection and characterization pipeline.
The successful candidate will develop algorithms to find accelerating stars in Roman survey data, fit population models to infer mass/velocity/spatial distributions of stellar remnants, contribute to other astrometry tasks, and publish results in peer-reviewed journals and conferences. This is a full-time on-site position in Tracy, California, United States.
Eligibility highlights: applicants must hold a PhD in physics or astronomy (or closely related field) with emphasis on astrometry, microlensing, or similar areas; have experience working both collaboratively and independently; be proficient in Python and high-performance computing; and have a documented publication record. Preferred experience includes large astronomical survey pipelines and numerical inference / stellar population synthesis tools.
Funding: this is a paid postdoctoral appointment with a listed salary of $123,048 annually. The appointment may be extended up to three years. LLNL also mentions benefits such as relocation assistance, education reimbursement, and flexible benefits.
Application: apply through the official LLNL careers portal using the provided job link. Note that NDAA Section 3112 eligibility restrictions apply, and selected external applicants must pass a post-offer drug test and background check process if required.
