Our client is a technology consultancy. Ready to work somewhere that cares more about how you build software than how fast you can ship it?

We don't measure developers by the number of tickets you complete. We care about engineering craft, clean design and thoughtful problem-solving. Our client consultants deliver in complex environments, pairing often and working with others who take pride in doing things properly: TDD, emerging design, refactoring and leaving code better than they found it.
