Collaborate with our development teams to deliver a highly performant and reliable live production platform
Ensure that your team members have the means and the environment to do meaningful, fun, efficient, and effective work

Cloud experience is desirable, preferably including AWS EC2, S3, RDS, and relevant auxiliary services
Networking experience, e.g. switch and firewall configuration and routing, is desirable
Experience with transforming growing environments of large-scale systems, including migration to modern architectures
