You are excited by new technology and new approaches to development, and are keen to promote their use in an enterprise setting. You are detail oriented, and don't mind getting your head down writing or reviewing code. You are happy to be on-call, though you aim to contribute to our software in such a way as to limit or even remove the need for anyone to be on-call.
