Senior Test Engineer - Data Platforms

Test Engineer – Data Platforms Role Overview

We are seeking an experienced Lead Test Engineer to take full ownership of the testing approach for data pipelines and data products within a modern Azure data platform. This role is hands‑on: you will design, implement, and execute test strategies across the stack, working alongside data engineers, BI developers, and architects to ensure robust, high‑quality, and reliable solutions.

The platform leverages Azure Databricks, Azure Data Factory, Azure Data Lake Storage, and Power BI. As the sole test specialist, you will embed quality engineering into every stage of delivery, acting as the authority on data testing practices.

• Test Ownership & Strategy

  • Establish automated testing frameworks and ensure they are embedded in delivery processes.
  • Act as the subject matter expert for data testing, advising engineers and stakeholders.
• Hands‑on Testing
  • Design and execute test cases across data ingestion, transformation, storage, and presentation layers.
  • Implement automated validation for data pipelines (Databricks notebooks, ADF workflows, ADLS layers).
  • Validate Power BI dashboards and reports for data accuracy, performance, and usability.
  • Perform exploratory, regression, and performance testing as required.
• Quality Assurance
  • Set up data quality checks, reconciliation processes, and monitoring.
  • Ensure compliance with data security and governance requirements.
  • Integrate test execution into CI/CD pipelines to enforce quality gates.
• Collaboration
  • Work closely with data engineers to embed testing at source.
  • Partner with architects and product owners to define acceptance criteria.
  • Represent testing considerations in sprint planning and delivery reviews.

• Strong track record as a Test Engineer in data engineering or analytics projects.
• Expertise in testing Azure data services:
  Databricks, ADF, ADLS, and Power BI.
• Proficiency in SQL and data profiling for test design and validation.
• Hands‑on experience with test automation frameworks for data (e.g., Python/Pyspark, Great Expectations, Pytest, dbt tests, or equivalent).
• Practical knowledge of CI/CD integration (Azure Dev Ops, Git Hub Actions, or similar).
• Excellent problem‑solving skills and the ability to work independently as the sole testing specialist on a delivery team.

• Familiarity with public sector delivery frameworks and regulated data environments.
• Experience of data performance testing and monitoring.
• Knowledge of Agile delivery methods and Dev Ops practices.
