We continuously innovate to help businesses identify ideal customers, reach key decision-makers, and accelerate growth through data-driven insights. The Opportunity We're looking for a Software Engineer III to join the Analytical Data team - the team that builds and runs the lakehouse for ZoomInfo's Data organization. ZoomInfo's data about people and companies is produced by many teams and used by many more: analysts, data scientists, product managers, and, increasingly, AI agents. We are building one governed source of that data for all of them. Each dataset is written once as Apache Iceberg tables, kept on both Google Cloud Storage and Amazon S3, and queried in place by BigQuery, Snowflake, and Starburst/Trino - no separate copy or export pipeline per engine. The goal is that anyone in the Data organization, person or agent, can query fresh, trusted data without an engineer in the loop. This is a hands-on data engineering role. You will work across streaming and batch ingestion, Iceberg table management, multi-engine access, data contracts with producer teams, and the observability that shows the data is fresh and complete. Datasets run to hundreds of millions of records, and most refresh daily. What You'll Do • Build and run Kotlin and Apache Beam pipelines on Google Cloud Dataflow that load data from Kafka and cloud storage into Apache Iceberg tables. • Keep large Iceberg tables correct, fast, and cost-efficient with good partitioning, Spark maintenance jobs (compaction, deduplication, snapshot expiry, orphan-file cleanup), and reconciliation against the source. • Make each dataset queryable from BigQuery, Snowflake, and Starburst/Trino through Iceberg catalogs and stable consumer views. • Work with producer teams on schemas and data contracts, and keep publishing a new dataset simple and documented. • Build the observability that shows each dataset is fresh, complete, and within budget: Datadog dashboards and monitors today, AI agents for alert triage next. • Own your pipelines in production, from incident response to the fix that keeps the problem from coming back. • Ship through code review, CI/CD, staged releases, and unit, integration, and end-to-end tests, with infrastructure managed in Terraform across GCP and AWS. • Work daily with data consumers, producer teams, and platform teams, and help shape the platform's technical roadmap. Must-Have Qualifications Data Engineering and Distributed Systems • 3+ years of professional software engineering experience, with a focus on data engineering or distributed systems. • Strong programming skills in Kotlin, Java, or Python. Our ingestion pipelines are written in Kotlin and our table maintenance and orchestration in Python, so you will work in both. • Hands-on experience with Apache Beam (ideally on Google Cloud Dataflow) or Apache Spark. • Experience with Apache Kafka or a similar streaming platform in production pipelines. • Experience with very large datasets and distributed systems, inc
