You will be: - Proposing and driving the architecture for user-data handling across Airflow, Spark, dbt and BigQuery, including encryption points, derived tables, backfills and partitioning. - Migrating existing pipelines one at a time while keeping their outputs unchanged, using a regression harness you build. - Designing and introducing processes the team will use after the migration, including pipeline change reviews, testing standards, incident post-mortems and release checklists. - Refactoring pipelines to remove duplicated steps and copy-pasted logic. - Building verification jobs to demonstrate that data-lifecycle rules are followed end to end. - Pairing with and mentoring a data engineer, with the goal of enabling the team to own the migrated pipelines independently. - Sharing pipeline maintenance and incident handling, and addressing root causes. - Documenting key decisions in concise architecture decision records. Your profile: - Deep hands-on experience with Airflow, Spark, dbt, BigQuery and Python. - A track record of technically leading at least one pipeline migration from start to finish. - Experience refactoring a live pipeline and proving that its output remained unchanged. - Proven ability to introduce engineering practices such as testing, code review and incident handling, and help a team adopt them consistently. - Mentoring experience with a concrete outcome. - A hands-on approach to technical decisions, combined with the ability to support and guide other engineers. Work from the European Union region and a work permit are required. Nice to have: - Experience with encryption at rest, data retention or deletion compliance, for example GDPR. - Experience with envelope encryption and a key manager such as GCP KMS, BigQuery AEAD functions or Tink. - Experience with BigQuery column-level security, policy tags or Data Catalog. - Experience with Config Connector (KCC) for managing GCP resources from Kubernetes. - Experience working with Kafka events.
