What you should have - U.S. Citizenship or Permanent Residency (Green Card holder). We are unable to provide visa sponsorship for this role. - 10+ years of software, platform, or infrastructure engineering experience, including time spent supporting data-intensive systems or data platforms. - Excellent communication skills and the ability to collaborate across cross-functional teams. - Proven experience in building, deploying, and operating distributed infrastructure at scale. - Strong technical background with big data and infrastructure technologies — such as Pinot, StarRocks, Trino, EMR, Airflow, Hive Metastore, Kubernetes, or equivalent systems. - Proficiency in Python, Golang, Bash, and SQL. - Proficiency with CI/CD (GitHub Actions), Vault, Terraform, Chef, and Grafana. - Deep understanding of infrastructure reliability, observability, and cost efficiency principles. - Hands-on experience supporting data pipelines or data engineering workflows is a strong plus. - A strong sense of ownership and a drive to deliver high-impact, autonomous results. What we value Slack has a positive, diverse, and supportive culture—we look for people who are curious, inventive, and collaborative. We seek engineers who care deeply about craftsmanship, reliability, and empowering others. In our work together, we strive to be smart, humble, hardworking, and—above all—collaborative.
