You will work with real-time data streams, optimize for performance and reliability across browsers, and collaborate closely with Product, Design, Search Infrastructure Engineers, Machine Learning Engineer, and Quality Engineers to spec, build, test, and deploy new features. We have frontend engineers in almost every team across Slack, and in that role, you’ll be making some of the most significant decisions for the company.
