Job Description
Curinos is building a Data Validation Suite that ensures the accuracy, consistency, and reliability of our data APIs and backend data pipelines. We are looking for a QA Automation Engineer with strong API and UI automation skills, data testing aptitude, and a proven ability to leverage AI-powered tools across all QA activities. You do not need to be a full Data Engineer — we will train you in our Databricks workflows and ETL validation processes.
Responsibilities
1. API & UI Automation
- Build, maintain, and execute automated API validation suites using Postman/Newman and Python across multiple environments and datasets
- Design, develop, and maintain UI automation frameworks using Selenium or Playwright to validate data-driven web applications, dashboards, and reports
- Develop end-to-end automated test suites validating full data flow from backend data pipelines and APIs to front-end UI visualizations
- Ensure data rendered in UI components accurately matches underlying data sources and business logic
- Contribute to scalable and reusable automation frameworks with configuration-driven API coverage and maintainable Page Object Models
- Leverage AI coding assistants (e.g., GitHub Copilot, Claude) to accelerate test development and auto-generate test cases from OpenAPI/Swagger specifications and UI requirements
- Apply AI-powered visual testing and self-healing locator capabilities to detect UI regressions and reduce test maintenance effort
2. Data Validation & Quality Assurance
- Design and execute comprehensive data quality validation across platforms, including source-to-target mappings, transformation logic, and business rule enforcement
- Perform SQL-based data analysis in Databricks to validate completeness, accuracy, null handling, referential integrity, duplication, and aggregation correctness
- Validate schema evolution, data freshness, and cross-system reconciliation across upstream sources, data lake/warehouse, and downstream APIs
- Develop and maintain Python-based data quality frameworks, validation libraries, and automation pipelines
- Capture, version, and compare API responses across test runs using JSON baseline comparisons
- Ensure adherence to data governance, audit, and control requirements, with strong focus on financial and regulated datasets
- Use AI/ML-driven data profiling to detect anomalies, distribution shifts, and pattern deviations
3. Reporting & Root Cause Analysis
- Identify, analyze, and report data quality and automation failures, performing root cause analysis in collaboration with engineering and data teams
- Build and maintain quality dashboards using Power BI, Databricks SQL, or Python to track historical trends and validation outcomes
- Define, monitor, and report data quality KPIs including accuracy, completeness, timeliness, consistency, and validity
- Use AI-based summarization tools to auto-generate execution reports, defect summaries, and quality trend insights, including predictive indicators where applicable
4. Collaboration & Agile Practices
- Collaborate closely with Data Scientists, Engineers, Product Managers, and stakeholders to define data requirements and quality expectations
- Participate actively in Agile ceremonies and contribute to sprint planning, execution, and retrospectives
- Document test strategies, automation coverage, validation workflows, and API contracts in Confluence
- Leverage AI assistants for test planning, coverage gap analysis, risk-based prioritization, and consistent documentation maintenance
