Slack is looking for an expert Engineer to join us in Data Engineering. You will conceptualize, design, build and integrate scalable systems, platforms and tools that power the Data Warehouse.

As Slack’s data grows, the goal of the Data Infrastructure team is to provide the best blend of the tools and technologies that will strengthen the efficiency and dependability of the way we make decisions. Our Data Warehouse powers processing of our large and diverse datasets to allow our partners to focus on their strengths: data applications, data modeling, data analysis, search or machine learning.
