Software Development New York, NY 201–500 employees Founded 2018 Privately Held

Astronomer builds Astro, a managed orchestration platform centered on Apache Airflow, serving over 900 enterprises. The stack reveals a data-centric business: Snowflake, Databricks, dbt, and BigQuery dominate the analytics layer, while Kubernetes and multi-cloud infrastructure (AWS, Azure, GCP) signal operational scale. Current hiring is sales-led (8 roles) with strong engineering velocity (7 roles, mostly senior/staff), and active projects span observability, IDE tooling, and community contribution—indicating a shift toward making data pipelines more visible and developer-friendly as scale challenges (Kubernetes, observability, search) become acute.
