Test Lead – Data Testing
12 months contract
Onsite in Zurich, Switzerland
About the Role
We are looking for Test Lead to design, build, and maintain automation frameworks focused on data-related testing. The successful candidates will play a key role in strengthening our regression testing capability, improving test coverage, and increasing the speed and reliability of our data platform releases.
Key Responsibilities
· Define end-to-end test strategy, test plan, scope, approach, entry/exit criteria, and quality gates across
· Lead test planning, estimation, scheduling, and coordination of SIT, E2E, Regression, and UAT activities across cross-functional teams
· 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 close 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 genuine data/application defects and test/environment issues
· Document test frameworks, test cases, and results in a clear, maintainable way
· Continuously improve automation coverage, execution speed, and reliability
Required Skills & Experience
· Proven experience leading end-to-end test management for large-scale data transformation, migration, or enterprise platform modernization programs
· Strong, demonstrable understanding of data platforms and enterprise data — data warehouses, data lakes, ETL/ELT pipelines, data models, and data governance concepts
· 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 attention to data quality and detail
Preferred / Nice-to-Have
· Experience with cloud data platforms (e.g., Snowflake, Databricks, BigQuery, Azure Synapse, or similar)
· Hands-on experience building test automation frameworks (e.g., for regression testing) rather than only executing pre-built scripts
· Experience with automated test case design and automated test execution, ideally in data-centric environments
· Proficiency in at least one programming/scripting language commonly used in test automation (e.g., Python, Java, 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
Candidate Profile / Culture Fit
· Deep understanding of data — genuinely curious about how enterprise data platforms work, not just how to test them
· Fast learner, adaptable mindset — able to quickly get up to speed within our fast-paced, quick-learning culture
· Self-starter who can work with ambiguity and evolving requirements
· Strong communicator, able to work closely with both technical (data engineering) and non-technical stakeholders
