Red Hat just posted project management and engineering internships for Summer 2020.
The engineering internships are a great opportunity for those interested in getting involved with open source software projects, distributed systems, kubernetes, and the project management internship is an opportunity to guide and manage how these things get built.
FWIW, the RH engineering office is on 21st/Broadway and has a small startup feel to it (about 15-18 of us work here).
