On behalf of Beeswax, Sigma Software is looking for a Lead Data Platform Engineer to join Data Platforms Engineering (DPE) team. This team provides external customers and internal teams with queryable access to the billions of daily events in the bidding platform. It operates a large-scale distributed system that ingests millions of events per second and applies business rules to process and provide the events to customers in real time. The team also builds ETL pipelines using Snowflake Data Warehouse and synthesizes data sets that power customer dashboards, reports, and business intelligence tools.


Our customer is a rapidly growing US AdTech company Beeswax. Founded by three ex-Googlers, it has a highly technical team and an excellent technological culture.

Beeswax provides extremely high-scale Bidder-as-a-Service solutions in advertising technology, works with global businesses, and has to date raised $28M (incl. the most recent Series B raise of $15M).

Sigma Software works together with Beeswax to enable the delivery of numerous key components of the platform, and is looking for engineers to complement Beeswax engineering team and drive further development of the platform.


The project is about building the next generation of real-time bidding software that enables sophisticated marketers to break free from the limitations and constraints of opaque, one-size-fits-all programmatic buying platforms.

The streaming applications are written in Java, use Kinesis and handle a variety of scaling and configuration challenges. Batch ETL is managed by Airflow DAGs. Having an excellent working knowledge of SQL is critical as we do a number of the ETL steps in Snowflake, and a poorly written query could have a significant performance and cost impact.

As a Lead Data Platform Engineer, you will be involved in direct ownership and technical supervision of globally distributed engineering teams, including engineers in Ukraine and the U.S.
