There comes a point in the life of every engineer where they find themselves gnashing their teeth at the inefficiency and awkwardness of their build and development tooling. Most of us just grit our teeth and ignore it, but there’s something very satisfying about actually oiling the gears so they work properly. If the idea of being a real force multiplier for your team makes you feel proud, then come and help us make our development tooling world-class!
