Team Overview

We’re building a scalable feature platform that powers Ads ML by making high-quality features easy to build, share, and maintain. Our small but growing team works on projects like batch feature management, impression feature store, training set generation, and event-driven features—with streaming feature management on the horizon.

We are looking for an engineer with deep experience in building high-scale data infrastructure and ML platforms to help evolve and scale our feature management systems.

What You’ll Do

• Design and build data infrastructure that supports large-scale feature computation, transformation, and storage.
• Develop frameworks for batch and event-driven features with a focus on reliability, scalability, and ease of use.
• Drive improvements in data quality and governance through validation, anomaly detection, drift monitoring, and feature lineage tracking.
• Partner with ML engineers to ensure smooth integration of feature engineering workflows into ML production systems.
• Contribute to training set generation pipelines and ensure reproducibility and feature versioning for model development.
• Help shape the future of the platform by exploring streaming feature management and other next-gen capabilities.

What You Bring

• 5+ years in infrastructure/platform engineering or large-scale distributed systems.
• 2+ years hands-on experience with SQL-based cloud data warehouses (e.g., BigQuery, Snowflake, Redshift, Databricks)
• Proficiency with large-scale feature computation frameworks (Spark, PySpark, or Scala).
• Expertise in distributed systems (scaling, partitioning, fault tolerance, caching).
• Familiarity with ML production systems, especially ML feature platforms, is a big plus
• Knowledge of MLOps workflows – from feature engineering to training to online serving
