Our ideal candidate is a professional who has experience in the domain of data engineering, and knows how to design, implement and maintain data storages and pipelines using industry standard tools.

• products that are out of stock are not advertised
• regulatory requirements are met

• Participate in defining and monitoring SLAs, and follow SRE best practices to ensure the stability and availability of the system
• Build APIs for internal and external consumers of the data
• Affect the ROI for billions of dollars in ad spend

What We Are Looking For

• 3-5 years of industry experience
• Strong programming skills (e.g., Python, Scala and/or Java)
• Some experience with data processing frameworks (e.g., Spark, Flink, Databricks, Snowflake, BigQuery, Redshift, ClickHouse)
• Familiarity with streaming systems (e.g Kafka, Kinesis)
