Experience with Ruby is preferred, but not strictly required — you're ready to pick it up and write clean, idiomatic code. You are familiar with Software Engineering, Distributed Systems, Systems Architecture, and Service Oriented Architecture, and have a solid understanding of enterprise architecture patterns, (micro)services, and their trade-offs.
