For example, I stumbled upon ockam.io during my last job search (no affiliation, and never interviewed with them as they weren't actively hiring when I wrote to them last year). I vaguely remember there being a few others, though I can't remember any names off the top of my head (it has definitely gotten harder searching for those kinds of companies as most job ads are drowned out by all the blockchain jobs). Old job posts on https://this-week-in-rust.org/ often contain a few interesting companies.
(Shameless plug: If anyone is interested in working at a non-profit focusing on non-blockchain cryptography in the field of multi-party computation, the company I'm working at is hiring at the moment and the salary ranges [for a 4-day work week] are listed: https://sinefoundation.notion.site/SINE-Job-Board-d28eda00c5...)
(We’re mostly remote, but not entirely — we do have a local contingent in New York, but it accounts for less than half of our people, with the rest scattered throughout the Americas and Europe).
