Job description

We are seeking an innovative and detail-oriented Agentic AI Test Engineer to join our AI Engineering team. The ideal candidate will have strong expertise in AI/ML testing, LLM validation, autonomous AI agents, and software quality engineering. You will be responsible for validating the performance, reliability, safety, and accuracy of AI agents, multi-agent systems, and GenAI-powered applications across mobile, web, and enterprise environments. This role requires a strong blend of AI testing (70%) and software automation/quality engineering (30%) to ensure robust and scalable AI-driven products.

The candidate will have responsibilities across the following functions:

Agentic AI and GenAI Testing (70%):

• Design and execute testing strategies for Agentic AI systems, autonomous workflows, and LLM-powered applications.
• Validate AI agents' reasoning, planning, memory, tool usage, and decision-making capabilities.
• Perform functional, regression, performance, and behavioural testing for AI agents.
• Develop test scenarios for prompt engineering, response validation, hallucination detection, and output consistency.
• Evaluate AI model performance using metrics such as accuracy, reliability, latency, relevance, and safety.
• Conduct multi-agent orchestration testing and agent-to-agent interaction validation.
• Test integrations with LLMs (GPT, Claude, Gemini, Llama, etc. ), APIs, vector databases, and retrieval systems (RAG).
• Ensure compliance with AI governance, ethical AI, bias testing, security, and privacy standards.
• Identify risks related to hallucination, prompt injection, data leakage, adversarial attacks, and model drift.
• Create automated validation frameworks for AI-generated outputs.

QA and Automation Testing (30%):

• Develop and maintain automation test scripts using frameworks such as Selenium, Playwright, Appium, Cypress, or API automation tools.
• Perform functional, API, integration, and end-to-end testing.
• Work with CI/CD pipelines for automated quality validation.
• Conduct defect tracking, root cause analysis, and collaborate with engineering teams for issue resolution.
• Create and maintain test plans, test cases, and quality documentation.

Requirements:

• Bachelor's/Master's degree in Computer Science, Engineering, AI, or related field.
• 4+ years of QA/Test Automation experience with exposure to AI/GenAI testing.
• Hands-on experience in LLM testing, Prompt Testing, RAG validation, and Agentic AI systems.
• Strong understanding of AI evaluation frameworks, model behaviour analysis, and autonomous systems testing.
• Experience with Python, Java, or JavaScript for automation and testing.
• Knowledge of Prompt Engineering, LangChain, LangGraph, CrewAI, AutoGen, MCP, OpenAI APIs, or AI orchestration frameworks.
• Experience with API testing tools such as Postman or Rest Assured.
• Familiarity with cloud platforms (AWS, Azure, GCP) is a plus.
• Strong analytical, debugging, and problem-solving skills.

Good to Have:

• Experience in AI Safety Testing / Responsible AI.
• Exposure to Mobile Testing (Android/iOS) using Appium.
• Understanding of MLOps, vector databases, embeddings, and RAG pipelines.
• Experience with performance testing tools such as JMeter or Locust.
