Slack is looking for a Staff Data Engineer to join the Data Ingestion Team. As part of the Data Engineering organization, we build and operate the platform that ingests data into our Data Warehouse. We write software to manage the ingestion for thousands of stateful hosts and stateless real time logging events. Currently, our infrastructure handles 65PB+ of storage, processes ~900B records a day, 400+ ETL pipelines and 900+ Active Airflow DAGs. As Slack’s data grows (along with the number of customers, features and employees), the goal of the team is to build a highly scalable and resilient ingestion platform to acquire high quality data efficiently and provide easy to use workflow and orchestration capabilities for our downstream customers so that they can focus on their strengths.
You will build scalable services and tools to help partners implement, deploy and analyze data assets with a high level of autonomy and limited friction. You will play a meaningful role in making partner interactions with the Data Warehouse pleasant and productive. You will have deep technical skills, be a self-starter, detail and quality oriented, and passionate about driving data driven decisions and having a huge impact at Slack!
