You’ll be part of a global team supporting multiple SaaS environments that help make the world a safer place. We use Azure as our core, but host on multiple platforms due to specific needs and our rapid pace of development and acquisition. The environment is rapidly changing from IaaS to PaaS to server less. So you’ll need to both apply your current skillsets and learn new things on a daily basis to push the business forward. While you’ll ultimately need a diversity of expert level skills to succeed, having deep understanding and experience in just a couple of areas (monitoring, scripting, automation tools, etc.) may just get you in the door to a great career.
