About the Role

We are looking for a highly skilled AI Tool / Agent Testing Engineer to evaluate, validate, and ensure the reliability of AI agents, AI automation tools, and agentic workflows used across our analytics platform. This role blends test engineering, GenAI understanding, Python/PySpark proficiency, and agent development lifecycle knowledge. You will work closely with Data Science, AI Engineering, and Platform teams to ensure that AI agents behave predictably, safely, and in alignment with business and compliance requirements.

Responsibilities

• Agent & AI Tool Testing
• Design and execute test strategies for LLM agents, multi agent workflows, and automation tools.
• Validate reasoning paths, tool calls, workflows, and guardrails.
• Assess regression, functionality, performance, safety, and hallucination risks.
• Agent Development Lifecycle (ADLC)
• Partner with AI engineers on prompts, knowledge sources, skills, and tool integrations.
• Validate interoperability with APIs, databases, vector stores, and orchestration frameworks.
• Ensure accuracy, consistency, tool-call reliability, trace quality, and guardrail adherence.
• GenAI & Workflow Validation
• Test RAG systems for grounding and factual correctness.
• Validate sequential, loop, and parallel agent workflows.
• Ensure compliance with AI governance and security standards.
• Test Automation Frameworks
• Build Python/PySpark utilities to automate scenarios, input generation, metrics, and trace analysis.
• Develop reusable test harnesses for agent evaluation pipelines.
• Documentation & Reporting
• Produce test plans, scenario libraries, coverage reports, and defect logs.
• Deliver insights to Data Science & Engineering teams to improve reliability.

Qualifications

• 58 years of overall experience in software engineering, data science, or AI/ML development, with at least 3+ years focused on AI/LLM/GenAI testing or agent-based systems.

Required Skills

• Python expertise in scripting, automation, and debugging.
• Strong PySpark experience in distributed testing, data validation, and pipeline testing.
• Hands-on knowledge of GenAI concepts, including LLMs, prompting, context management, RAG pipelines, agent tool-calling, and multi-agent orchestration.
• Experience with agent development and deployment frameworks such as LangGraph, AutoGen, CrewAI, Copilot Studio Agent SDK, and Vertex AI/OpenAI agent frameworks.
• Solid understanding of agent architecture covering skills, tools, connectors, memory, guardrails, and observability.
• Familiarity with modern GenAI/agent evaluation frameworks such as Langsmith evaluation, AutoGen agent-behavior assessment utilities etc. for benchmarking reliability, grounding, tool-use correctness, and multi-agent performance.
• Strong foundation in functional and regression testing, scenario and edge-case testing, LLM safety and hallucination testing, and workflow validation.
• Experience creating evaluation datasets and defining success criteria for AI behavior.
• Good understanding of API testing frameworks, data engineering concepts, cloud workflow execution (Azure/GCP/AWS), and CI/CD pipelines for test automation.
• Excellent communication skills for cross-functional collaboration.
