Job Title: Test Automation Specialist – Data Testing

About the Role

We are seeking talented Test Automation Specialists to design, build, and maintain automation frameworks focused on data-related testing. The successful candidates will play a crucial role in enhancing our regression testing capabilities, improving test coverage, and increasing the speed and reliability of our data platform releases. This position straddles the fields of test automation engineering and data engineering: the ideal candidate will be equally comfortable working with enterprise data platforms and pipelines as well as automation tooling.

Key Responsibilities

  • Design, build, and maintain an automation framework for regression testing of data platforms and pipelines.
  • Develop automated test cases covering data ingestion, transformation, validation, and reconciliation scenarios.
  • Execute and maintain automated test execution cycles, integrating with CI/CD pipelines.
  • Identify gaps in existing test coverage and proactively design automated checks to address them.
  • Collaborate with data engineers, QA, and business teams to understand data flows and translate them into robust test scenarios.
  • Troubleshoot test failures, distinguishing between actual data/application defects and test/environment issues.
  • Document test frameworks, test cases, and results in a clear, maintainable manner.
  • Continuously enhance automation coverage, execution speed, and reliability.

Job Requirements

Experience:

  • Strong demonstrable understanding of data platforms and enterprise data, including data warehouses, data lakes, ETL/ELT pipelines, data models, and data governance concepts.
  • Hands-on experience building test automation frameworks (e.g., for regression testing) rather than solely executing pre-built scripts.
  • Experience with automated test case design and automated test execution, ideally in data-centric environments.

Essential Skills:

  • Proficiency in at least one programming/scripting language commonly used in test automation (e.g., Python, Java, or similar).
  • Experience with SQL and querying large/enterprise datasets to validate data accuracy and integrity.
  • Familiarity with CI/CD tools and integrating automated tests into deployment pipelines.
  • Strong analytical and problem-solving skills, with a keen attention to data quality and detail.

Nice to Have Skills:

  • Experience with cloud data platforms (e.g., Snowflake, Databricks, BigQuery, Azure Synapse, or similar).
  • Experience with test automation/ETL testing tools (e.g., Selenium, pytest, dbt tests, Great Expectations, or similar).
  • Exposure to financial services or enterprise data environments.
  • Experience working in Agile/Scrum delivery teams.

Culture Fit:

  • A genuine curiosity about how enterprise data platforms work, beyond just testing them.
  • A fast learner with an adaptable mindset, able to thrive in BJB's dynamic and quick-learning culture.
  • A self-starter who can navigate ambiguity and evolving requirements.
  • Strong communication skills, able to collaborate effectively with both technical (data engineering) and non-technical stakeholders.
