We manage the build pipeline that delivers Quip and Slack Canvas’s backend. A year ago, we were chasing exciting ideas to help engineers ship better code, faster. But we had one huge problem: builds took 60 minutes. With a build that slow, the whole pipeline gets less agile, and feedback doesn’t come to engineers until…
