Occasionally participate in 2nd line support during office hours, and sometimes out of hours (for which you’ll be paid an allowance and further hourly payment when on call)

Possibly manage a small number of less experienced developers

Help with hiring, taking part in recruitment of other developers

All our developers should have:

Experience of software development with significant knowledge of Ruby

A systematic approach to solving problems

Experience working in agile environments
