About the Position


As a member of the Cloud Engineering team, you are part of a team responsible for ensuring availability, reliability, responsiveness and scalability across all Contrast production services. You are deeply hands-on with our cloud-based infrastructure, database systems, automation, monitoring and systems telemetry. You work with our engineering team to design and build system infrastructure that is automated, elastic, and reliable. You support our databases in such a way that our colleagues in application engineering see you as a reliable subject matter expert for performance, modeling and data integrity. In a teammate, we expect you to challenge conventional wisdom and encourage everyone to have simpler solutions. It is your nature to share what you know so that everyone you encounter is just a bit better at using MySQL. Ideal candidates have expertise in maintaining and improving the use of MySQL. You’ll work with these systems through infrastructure as code using Terraform, Cloudformation and Helm Charts. All of our work is currently done in the AWS ecosystem. Cloudformation will leave our stack this year.
