About the assignment

We are looking for a Senior Data Engineer for an interim position in our Trust Intelligence & Calling department. Note: We prefer on-site but we're considering remote candidate as well. We are re-architecting our data pipelines to meet stricter requirements on user-data lifecycle: encryption, retention, and deletion across historical and derived data. You lead the technical migration and establish the engineering processes that keep the pipelines reliable after it.

 

Responsibilities

  • Propose and drive the architecture for user-data handling across Airflow, Spark, dbt, and BigQuery: encryption points, derived tables, backfills, partitions.
  • Migrate existing pipelines one at a time without changing their output, behind a regression harness you build.
  • Design the processes the team keeps after the migration: pipeline change review, testing standards, incident post-mortems, release checklist.
  • Remove duplicated steps and copy-pasted logic as you pass through each pipeline.
  • Build verification jobs that prove the data-lifecycle rules hold end to end.
  • Pair with and mentor a data engineer on the team, with the goal that the team owns the migrated pipelines independently.
  • Share pipeline maintenance and incident handling; fix root causes.
  • Document decisions as short architecture decision records.

 

Requirements

Mandatory

  • Deep hands-on experience with Airflow, Spark, dbt, BigQuery, and Python.

  • At least one pipeline migration you led technically from start to finish.

  • Experience refactoring a live pipeline while proving its output is unchanged.

  • Experience introducing engineering processes (testing, review, incident handling) to a team and making them stick.

  • Mentoring experience with a concrete outcome.

Nice-to-have

  • A prior project on encryption at rest, data retention, or deletion compliance (for example GDPR).

  • Envelope encryption with a key manager (for example GCP KMS), BigQuery AEAD functions, or Tink.

  • BigQuery column-level security, policy tags, Data Catalog.

  • Config Connector (KCC) for managing GCP resources from Kubernetes.

  • Events with Kafka.
