With these powerful audiences and analytics on their side, brands can build a sustainable marketing engine, creating impactful ways to engage consumers and fostering profitable growth with full-funnel solutions tuned to their data and goals.

About the role and the team

Our data engineering team architects data ingestion/pre-processing, data quality/governance and impactful machine learning pipelines. You will work in scalable ETL workflows as well as preprocessing data for machine learning models.

We run a cloud based stack with assets in both AWS and GCP. We use Kubernetes, Jenkins, Terraform, for our CICD infrastructure. We leverage React on top of a Springboot stack with PostgresQL as our primary relational database. The data engineering pipelines are based in S3 with a databricks/deltalake store with Scala/Spark being the tool of choice for our ETL pipelines running on Airflow/Jenkins and Kubernetes. We also have our proprietary data asset, the PebblePost Identity graph, that uses Neo4J and interfaces with Spark streaming. In addition we have real time streaming pipelines built using Kafka (MSK) for processing behavioral intent signals from our brand customers.

Our reporting infrastructure leverages our delta lake via a combination of tools including AWS Athena, Metabase and Sisense. We are continuously evolving our architecture to match our growing scale and recently incorporated graph databases and streaming pipelines to evolve our Identity solution.
