    Spreedly Systems Engineer Work Sample

Being a company founded by developers, it's in our DNA to automate as much as we can and deploy as often as possible in order to allow for rapid development, innovation, and reduced human error. Spreedly relies on many internal services for its infrastructure. Your role as a Systems Engineer at Spreedly will involve:

understanding how all the pieces that comprise the infrastructure fit together
knowing how best to maintain and secure that infrastructure
automating provisioning, testing, and maintenance as much as possible
measuring and monitoring system fitness
delivering services that other engineering teams can utilize in support of their development efforts
communicating well with the rest of the team and the wider technical community

This script allows you to upload multiple cookbooks automatically.
Use -d to download the cookbooks
Use -p to purge cookbooks

Using either option will require some user input
