We are looking for a seasoned Senior QA Engineer to join our advertising technology team. You will own quality across the full stack — from data pipelines and backend services to customer-facing UI — and embed testing excellence into every stage of our CI/CD delivery process. You thrive in fast-paced environments, ramp up on new business domains quickly, and bring a data-driven mindset to every challenge.

CORE RESPONSIBILITIES

Regression Test Suites

Design and maintain comprehensive suites covering UI workflows and PySpark-based backend data pipelines.

Functional Testing

Validate ongoing feature releases against acceptance criteria, ensuring correctness across edge cases and integrations.

Load & Smoke Testing

Execute load tests to validate system performance under realistic traffic, and run smoke tests to catch critical regressions fast.

CI/CD Integration

Integrate regression suites into CI/CD pipelines using CD best practices, enabling automated quality gates on every merge.

Data Analysis & Validation

Analyze test results and system outputs to surface trends, flakiness, coverage gaps, and data quality issues.
