Position Summary
The Lead QA Automation Engineer is a senior individual contributor responsible for designing, developing, and maintaining automated test solutions across Ontada’s product ecosystem, with a strong focus on AI-enabled and GenAI-powered systems. Reporting to the QA Manager, this role drives high-quality automation for UI, API, backend, and data layers, while ensuring AI/ML features meet expectations for correctness, reliability, safety, and compliance.

This role partners closely with Product, Engineering, and Operation teams to validate both traditional software workflows and AI-driven behaviors, including prompt-based systems, retrieval-augmented generation (RAG), and model-integrated services

Key Responsibilities

Quality Engineering Ownership & Execution

• Own and execute test strategy, planning, and execution for assigned features, services, or product areas

• Identify functional, integration, and non‑functional quality risks early; communicate risks, impacts, and recommendations clearly.

• Author comprehensive test strategies, test plans, and test cases aligned with product requirements and acceptance criteria.

• Perform exploratory testing to uncover complex, edge‑case, and systemic defects.

• Coordinate end‑to‑end validation across multiple environments to ensure release readiness.

Test Automation & Framework Development

• Design, develop, and maintain automated test suites across UI, API, service, and data layers.

• Contribute to the enhancement and maintainability of automation frameworks using tools such as Selenium, TOSCA, etc.

• Develop robust API automation using RestAssured, Postman, or equivalent frameworks.

• Implement effective test data strategies, including synthetic data generation and environment setup.

• Integrate automated tests into CI/CD pipelines to support fast and reliable feedback cycles.

• Leverage AI‑assisted development tools (e.g., GitHub Copilot, Claude Code, or similar) to accelerate test automation development, refactoring, and debugging while maintaining code quality and security standards.

• Use AI tooling to assist with test case generation, edge‑case identification, and data‑driven scenario expansion, validating all outputs through engineering judgment and established QA practices.

AI / GenAI Quality Engineering

• Design and execute test strategies for AI/ML and GenAI‑powered features, including LLM‑based workflows.

• Validate prompt behavior, prompt templates, and prompt chaining across different scenarios and data contexts.

• Perform negative testing for AI systems, including prompt injection, jailbreak attempts, hallucination risks, and unsafe outputs.

• Test Retrieval‑Augmented Generation (RAG) pipelines, including:

  • Embedding quality validation

  • Retrieval accuracy, recall, and relevance

  • Chunking and indexing strategies

• Validate AI outputs for accuracy, consistency, explainability, and compliance in regulated environments.

• Collaborate with Engineering and Operations teams to test model integrations, configuration changes, and inference pipelines.

• Utilize AI‑powered tools to support prompt analysis, test scenario exploration, and hypothesis generation when validating LLM‑based features and AI workflows.

• Critically evaluate AI‑generated suggestions and outputs to ensure accuracy, safety, reproducibility, and regulatory compliance.

Backend & Data Testing

• Perform advanced backend testing across SQL and NoSQL data systems.

• Validate data ingestion, transformations, persistence, and integrity across services and environments.

• Coordinate testing of asynchronous workflows and integrations (e.g., message queues, APIs, batch processes).

Agile Collaboration

• Work closely with Product Owners and Business Analysts to refine user stories, define acceptance criteria, and ensure testability.

• Partner with developers during design and implementation to support shift‑left testing.

• Participate actively in sprint planning, grooming, retrospectives, and release readiness reviews.

• Collaborate with onshore and offshore QA team members to ensure consistent execution and quality standards.

Quality Governance, Compliance & Continuous Improvement

• Ensure testing activities align with HIPAA and other regulatory, security, and data‑privacy requirements.

• Contribute audit‑ready documentation, including test plans, execution evidence, and reports.

• Participate in root‑cause analysis for quality or performance issues and support corrective actions.

• Identify opportunities for improving QA processes, tools, and documentation; contribute suggestions through established continuous improvement channels.

• Research and evaluate new QA, automation, or performance testing, AI assisted tools and techniques as appropriate.
