OpenX runs a supply-side advertising platform on a GCP-centered data stack (BigQuery, Dataflow, Spark, Airflow, dbt, Vertex AI) with Java, Scala, Go and Erlang on the serving side. Current hiring is commercially weighted rather than engineering-led, focused on building buyer development in the DACH region and pushing CTV supply into Canada and LATAM. Finance roles point to pressure on forecasting, month-end close and reporting automation.
