CodeWeavers in St Paul, MN
<a href="https://www.codeweavers.com/about/general/jobs/" >
You might recognize CodeWeavers as the main force behind the Wine project. We're a small company, fewer than 20 people in our main office.
We're looking for a quality C programmer to do Linux systems programming work. Specifically stuff like mail servers (Dovecot, Postfix), display technologies (X server, SPICE), and just general open source systems programming.
It's a very fun workplace. I've been employed here more than five years and I can't imagine a better work environment. Link above contains the full job listing at a Linked-In jobs page, and an email address if you prefer that contact method.
