What are good, well paying cybersecurity roles that involve knowing Linux?

I graduated almost 3 years ago and have been working full time in the field since (in security engineering). I recently got my Red Hat Certified System Administrator certification, as I really like Linux. What are good, well paying roles in cybersecurity that Linux would be used in? Would pentesting be one? Someone had mentioned to me recently that if I like "breaking puzzles", I could find pentesting an interesting option. Thoughts?
