* Experience with AWS or another major cloud platform and deploying production data pipelines.
* Experience with a services language such as Go, Rust, or TypeScript.
* Strong understanding of data lineage, versioning, reproducibility, and data quality.
* Experience building backfill and reprocessing systems.
* High ownership and ability to operate independently in a startup environment.
* U.S. citizenship required.
Strong Plus
* Founding or early data-platform engineering experience.
* Experience with sensor, audio, video, telemetry, or geospatial data.
* Airflow, Prefect, MLflow, W&B, or similar tooling.
