Job Overview

We are seeking a highly skilled Senior QA Engineer specializing in AI and Machine Learning to join our growing team. The ideal candidate will play a pivotal role in ensuring the quality, reliability, and performance of our AI-driven products and platforms. This position requires a strong foundation in software testing, automation, and QA strategy, combined with an understanding of machine learning workflows such as RAG pipelines, inference APIs, and generative AI applications. The successful candidate will collaborate closely with ML engineers, data scientists, and developers to design and execute comprehensive test plans that validate model behavior, system integrations, and end-to-end user experiences.

Responsibilities

• Design and execute manual and automated test cases for backend APIs, frontend interfaces, and end-to-end AI workflows.
• Conduct exploratory testing of new generative AI features and user interactions.
• Develop and maintain automated test frameworks for UI and API.
• Build automation scripts for AI/ML pipelines using pytest, unittest, or custom frameworks.
• Create comprehensive test plans, manage defects, and report results using Jira, or similar tools.
• Validate RAG (Retrieval-Augmented Generation) pipelines, including embedding accuracy, retrieval quality, and model response evaluation.
• Test AI agents and orchestration flows, ensuring correctness in multi-step reasoning and tool invocations.
• Perform performance and scalability testing for ML inference endpoints (SageMaker, Bedrock, custom APIs), monitoring latency and throughput.
• Conduct integration testing across data ingestion, preprocessing, inference, and output pipelines.
• Validate UI/UX and Gen AI interaction flows, ensuring a consistent and intuitive user experience across devices and browsers.
• Automate end-to-end test scenarios, including document upload, retrieval, summarization, and inference workflows.
• Integrate and maintain automated test suites within CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins).
• Collaborate closely with ML engineers, data scientists, and developers to reproduce issues, validate fixes, and ensure model reliability.
• Ensure security, compliance, and data privacy standards are upheld for sensitive datasets during testing.

Skills & Experience

• Strong experience in manual testing of backend APIs, frontend apps, and full-stack systems.
• Hands-on with test automation tools: Selenium, Playwright, Cypress, Postman, REST-assured, or Python-based frameworks.
• Proficient in test case design, bug reporting, and defect tracking (Jira, Trello, or equivalents).
• Familiarity with AI/ML workflows — especially LLM-based applications, RAG pipelines, embeddings, and model inference.
• Experience with performance testing tools or frameworks; understanding of latency, throughput, and scaling metrics.
• Knowledge of CI/CD automation and integrating tests into build pipelines.
• Understanding of API testing principles: CRUD operations, authentication, edge cases, and error handling.
• Familiar with UI/UX validation and cross-browser compatibility testing.
• Strong analytical and communication skills — able to describe AI-related issues clearly and reproducibly.
• Awareness of security and compliance practices for testing sensitive or proprietary data.

Education:

• A Master's degree in Machine Learning, Computer Science with a preference for specialization in the NLP domain.
