Senior Software Engineer, Frontend Builds & Tooling - Slack
The Frontend Developer Experience team empowers developers to write, build, test, and deploy code seamlessly across mobile, desktop, and multiple operating systems while solving unique scaling challenges. That means improving reliability, speeding up feedback loops, reducing cognitive load, and actively listening to developer pains to prioritize the work that matters most.
