Software engineer multi-classing

I can think of specific instances where I've done each of these roles in my software engineering job:

• Tech support
• Sysadmin
• DevOps
• QA (oh do I have a story about this one)
• Management
• Release management
• Agile coach
• Security engineer/pen tester
• Compliance
• Custodian

As well as customer relations. I don't know that I've ever done much product management, though.
