The Experience

Slack is looking for a senior software engineer to join the Data Ingestion Team.

Currently, our infrastructure handles 180PB+ of storage, processes ~1T records a day, 400+ data pipelines and 1500+ 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 leveraging modern Streaming and Lakehouse technologies.

As a Senior Engineer, you will play a key role in driving our streaming and lakehouse strategies while also building highly scalable services and tools to help our customers acquire large volumes of high quality data at scale and making customers’ interactions with the ingested data pleasant and productive.

• Automate and handle the lifecycle of datasets (schema evolution, metadata management, change and backfill management, deprecation and migration).
• As one of the tech leads, comfortably collaborate with cross functional partners and lead technical initiatives independently end to end.
• Be a role model and a multiplier, coaching and mentoring other engineers across the team and the org.
• Write, review, or provide feedback on a technical design proposal from others.

• You are proficient in object-oriented and/or functional programming languages: SQL, Python, Java/Scala, Go or equivalent
• You are skilled at crafting and building robust distributed microservices with tools like Kubernetes, Docker, AWS ECS/EKS, Terraform, Grafana, etc.

Even Better If:

• You are familiar with AI-assisted software development and automation and have hands on experience of Claude Code/Codex or equivalent
• You have excellent written and verbal communication and interpersonal skills; able to effectively collaborate with cross functional partners and explaining sophisticated technical concepts to non-technical stakeholders
