Senior Frontend Engineer - Search, Learning & Intelligence

The Search, Learning, & Intelligence (SLI) team at Slack is looking for experienced frontend engineers to help build features that make Slack smarter the more companies use it. Our goal is to help users feel less overwhelmed by Slack’s information avalanche and give them superpowers to find fast answers — whether from their coworkers, search, or bots.  We’re hiring engineers to help us build scalable, reliable data-driven product features and the services and infrastructure that back them.
