Description
Senior Software Engineer, Frontend - 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. We’re shaping a development environment where engineers stay in flow with fast builds, minimal friction, and tooling that feels intuitive rather than intrusive. As part of the DevXP Pillar, we focus on enhancing developers' experiences and productivity through tooling, processes, and support. As part of this team you will be making the development inner loop faster of hundreds of developers by making the FE toolchain efficient and reliable.
