Experience developing, maintaining, and monitoring large data pipelines with an orchestration tool (Airflow, Dagster, or dbt) for batch and a streaming framework (Apache Beam, Kafka Streams, Flink, or similar).
Solid grasp of large-scale data fundamentals — partitioning strategies, SQL query performance optimization, cost/performance tradeoffs.
Experience developing data models that support scalable, cost-effective analytics and ML pipelines.
Experience writing data quality checks and unit and integration tests to ensure high-quality data and analytics.
Experience creating analytics solutions with visualization tools such as Looker or Tableau.
Proficiency with version control (Git).

Experience with containerization tools such as Docker.
Bachelor's or Master's degree in a relevant field, or equivalent practical experience.

Responsibilities

Design, build, and maintain scalable, reliable data pipelines (batch and streaming) with Airflow, Beam, and Python — including the data quality checks, testing, monitoring, and error handling that keep them trustworthy.
Design data models that make analytics and ML pipelines scalable, repeatable, and cost-efficient.
Write and optimize complex SQL (CTEs, window functions) and streaming pipelines in Python.
Partner with data science, engineering, and product to turn data needs into solutions.
Build RADAR's data product offering — turning our real time inventory and location data into actionable insights for our retail partners — and the visualizations and dashboards (e.g. Looker) that turn data into decisions.
Own the technical direction of the data platform — architecture, technology, standards, and roadmap.
Mentor data engineers and set the standards the team builds on for scalable and reliable data pipelines.
