Overview
We are seeking highly skilled and experienced QE Test Engineers/ SDETs within a complex, multi-vendor data migration transformation programme. This role is for hands-on quality engineering professionals responsible for the design, implementation, and execution of automated data tests within the enterprise data platform. The ideal candidate will have a strong background in testing the implementation of data solutions on AWS infrastructure and a variety of core and supplementary technologies. This role requires a solid understanding of data engineering, cloud services, and the ability to assure quality solutions. This role operates within an agile delivery team in a Data Factory model and focuses on technical validation of data pipelines, transformations, and analytical outputs to ensure high levels of data quality, accuracy, and reliability for a data migration transformation programme.
Responsibilities
- Design, develop, and execute automated data tests in line with functional requirements, non-functional requirements and acceptance criteria; validate data quality dimensions.
- Implement source-to-target reconciliation, schema validation, and transformation testing in ETL/ELT environments.
- Collaborate with cross-functional teams in a multi-vendor environment to translate business requirements into technical testing solutions.
- Translate data mappings, business rules, and transformation logic into automated test scenarios; develop reusable and maintainable test scripts using approved automation frameworks.
- Test data feed pipeline migrations repointing from an existing Data Warehouse to a new AWS Data Lakehouse architecture, with AI ETL accelerators, Python/PySpark, SQL and YAML configurations; test initial bulk and subsequent deltas from legacy to new.
- Execute automated test suites as part of sprint-based delivery and regression cycles.
- CI/CD & Delivery: Run automated tests within CI/CD pipelines and scheduled testing runs; ensure test assets are version controlled and aligned with delivery processes; support release activities by validating data readiness and quality gates.
- Documentation & Reporting: Maintain documentation for test cases, test results, and quality metrics; provide clear status updates on testing progress and outcomes; support audit, governance, and compliance related to data quality.
- Collaboration & Engagement: Work with Data Engineers, Platform Engineers, Product Owners, Business SMEs, and third-party partners to ensure connected technical testing solutions; review implemented Unit tests for data processing applications.
Qualifications
- Experience in data engineering testing; strong knowledge of AWS data pipelines, Data Warehouse, Data Lakehouse, ETL/ELT processes, data quality concepts, and related testing methodologies.
- Experience building advanced test automation frameworks from scratch using object-oriented and scripted languages; breadth across different tech stacks.
- Proficiency in JavaScript/TypeScript, Java, C#, Python (two or more); strong understanding of object-oriented programming.
- Experience in AWS cloud services (AWS Glue), Python/PySpark, SQL, YAML configurations, and CI/CD tools (GitHub Actions or similar).
- Knowledge of AI-driven testing solutions and automation accelerators; solid understanding of data feeds architectures and best practices.
- Strong problem-solving, data quality, defect management, and reporting skills (e.g., JIRA, XRAY, ADO); API/interface testing is a plus.
- Non-functional testing experience and AWS fundamentals; AWS Certified Data Engineer is a plus; familiarity with HDFS.
- Understanding of data governance and data security considerations; ability to work in a multi-vendor environment.
Benefits and Inclusion
- We offer tailored benefits supporting physical, emotional, and financial wellbeing; Learning and Development opportunities; and flexible work options.
- We are an equal opportunities employer and are committed to promoting equity and diversity; we actively collaborate with individuals who have disabilities and long-term health conditions to remove barriers to employment.
