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
