Sift Tech Stack

Fraud detection platform powered by machine learning and behavioral data

Computer and Network Security San Francisco, California 201–500 employees Founded 2011 Privately Held

Sift operates a fraud-detection platform built on Python, Java, and Kafka, ingesting behavioral signals across payment, account, and content-abuse vectors. The tech stack reflects a data-intensive operation: Snowflake for analytics, Spark for batch processing, GCP/AWS for multi-region deployments, and Kubernetes for orchestration. Current hiring skews engineering-heavy (7 of 20 open roles), with active projects around multi-region infrastructure and bot-detection automation—indicating infrastructure scaling and operational complexity rather than feature velocity.
