About Slack Product Security:

Our Product Security Team supports the following tenet of Slack’s mission: make people’s working lives more secure. We’re serious about building a simple-to-use yet secure product, and most importantly, protecting our customers’ data. We take a systematic approach to security and strive to ensure we provide low friction, and high-impact security across everything we do. As a member of the Product Security team, you care about shipping secure products and ensuring the way in for the bad actors is never through the front door (or the back)! You are passionate about enabling our developers to ship secure products. You think about your team as not fixing bugs but developing effective ways to prevent them. Your work will directly impact the way millions of people, teams, and businesses get things done using Slack.

Slack has a positive, diverse, and supportive culture—we look for people who are inquisitive, inventive, and work to be a little better every single day. In our work together we aim to be smart, humble, hardworking, and, above all, collaborative. If this sounds like a good fit for you, read on ahead!
