Low Level Programming and DevOps Expert

I have over 20 years in the industry starting out as a Linux SysAdmin / Network Engineer and now doing more Systems / Low level Programming, R&D, and occasional DevOps. Looking for opportunities involving low level / embedded systems / backend software development. Happy to also do automation / SysAdmin / DevOps as well. Although not my forte, I like to do robust automated testing / QA for software to ensure they meet (potentially undocumented) requirements.
