Senior Data Developer

What you'll do

• Design and build scalable ETL/ELT pipelines for BigQuery, using Python and SQL.
• Lead our implementation of DataForm for version-controlled, testable SQL transformations.
• Define and maintain engineering standards: code review, CI/CD, monitoring, and testing.
• Work with analysts, product engineers, and the AI team to turn business needs into robust data models.
• Mentor teammates and help level up how Journey works with data.

• Migrating legacy Databricks ETL to GCP-native tooling.
• Building cross-cloud ingestion pipelines (e.g., S3 or ADLS → BigQuery) as we consolidate data from partners.
• Setting up a DataForm-based transformation layer from scratch.
• Defining CI/CD and monitoring standards for the data platform.

What you'll bring

• Strong production experience with Google Cloud Platform, especially BigQuery (partitioning, clustering, cost/performance tuning).
• Hands-on experience with DataForm.
• Advanced SQL proficiency—window functions, complex joins, and query optimization.
• Solid Python skills for pipeline engineering and tooling.
• Thorough understanding of ETL/ELT: orchestration, idempotency, data quality, observability.
• Comfort with CI/CD practices and Git-based workflows (GitHub Actions, GitLab CI, etc.).
• 5+ years in data engineering, with at least 2 years focused on GCP.

• Experience with Databricks or PySpark in production environments.
• Familiarity with AWS or Azure data services.
• Exposure to Infrastructure-as-Code (Terraform).
• Knowledge of data streaming technologies (Pub/Sub, Dataflow, Kafka).
• Partnering with analytics or ML teams.
• Ability to communicate clearly with non-technical colleagues.

What you'll get

• Direct ownership and influence over a critical business platform.
• You will join a team of disruptive thinkers, digital specialists and tech pioneers.
• High quality hardware and development tools.
• Flexible working — in the beginning we expect mostly office collaboration but over time you will get more remote flexibility.
• Regular company off-sites.

• In it together: We've got each other's backs. No ego, no silos.
• Driven by success: When our clients win, we all win.
• We're pioneering: The biggest risk is not taking any.
