Engineering Manager, Infrastructure

Slack has a positive, diverse, and supportive culture—we look for people who are curious, 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, why not say hello? 

Our Infrastructure team is the scalability of Slack! We build all of the back-end systems that ensure that Slack has high availability, is incredibly performant for any size team anywhere in the world.  We operate at tremendous scale with systems that process millions of events per second. Our systems enable our product engineers to move fast and build awesome features rapidly on top of them.

We know we’ve done our job correctly when none of our users think about us. We don’t typically ship new user-facing features, but rather ensure our systems are incredibly performant, highly available, reliable, resilient, and scalable. In other words, Slack just works seamlessly.

We are a small team making a large impact. We rapidly iterate and work closely with other teams in engineering to ensure we build resilient systems that can scale. We have a strong commitment to quality and understand that simplicity and reliability should be the primary aspects of the systems that we build. We are scrappy, independent, and pragmatic. Infrastructure is a diverse and inclusive team that treats their colleagues exceptionally well.

Slack's API and web backend is built on PHP/Hack, and our backend services are written in Java and Go. Our data infrastructure is built on Kafka, Hadoop, Hive, Presto, Spark, and MySQL.
