Your future duties and responsibilities:

Get ready to be part of something big! We're gearing up for a hardware and software refresh on our current system.

Picture this: DevOps / automation will be our secret weapon. We're revamping our deployment and testing processes, and that means exciting opportunities for you to dive into the world of automation and make a real impact.

Think configurable PowerShell DSC/Ansible scripts guiding the way as we seamlessly deploy our applications across different environments.
So, if you're ready to be part of a team that's not just keeping up with the times but setting the bar for innovation, then buckle up – because the ride ahead is going to be electrifying. Join us on this journey as we revolutionize our system and pave the way for a brighter, more automated future!
