Simons Foundation (the parent institution of Flatiron Institute, where I work) has just announced grants to support professors working on scientific software, with a plan to support 6 new fellows per year. From the call for proposals:

A Scientific Software Fellowship provides five years of 50 percent salary support of the awardee’s academic-year salary and fringe benefits, whether normally paid over 9 or 12 months, along with a yearly $50,000 research allowance for the awardee…

Letters of intent are due 8 December 2023.

It’s clear these are not career transition awards and will instead go to people already involved in scientific software. While this call is aimed at physics, astrophysics, and mathematics professors, stats might qualify (you should check if you’re interested). I’m not involved in reviewing the grants—that’s the folks across the street.
