Role

Summary:

This role goes beyond traditional QA; the ideal candidate should be capable of validating, evaluating, and improving AI-powered systems, agents, copilots, and LLM-driven workflows while building scalable automation frameworks and intelligent quality solutions. You will work closely with Engineering, AI/ML, Platform, Product, and Dev Ops teams to ensure reliability, safety, observability, scalability, and quality of modern AI-native applications and Agentic systems.

• Design, validate, and optimize testing strategies for AI-powered applications, copilots, chatbots, RAG pipelines, and autonomous AI agents.
• Develop AI evaluation (Evals) frameworks for:
  Hallucination detection Groundedness Toxicity & bias validation Response quality Context relevance Prompt regression testing Determinism & consistency Safety and guardrail validation
• Build automated validation pipelines for LLM outputs using structured assertions, semantic scoring, embeddings, and evaluation metrics.
• Create synthetic datasets and benchmark datasets for AI testing scenarios.
• Test multi-agent orchestration workflows and agent memory/context retention.
• Validate MCP (Model Context Protocol) integrations and tool interoperability.
• Work on Context Engineering, Prompt Engineering, and Prompt Optimization strategies.
• Evaluate latency, token usage, model cost optimization, throughput, and scalability.

• Develop and maintain scalable UI/API automation frameworks using:
  Python (mandatory)
  Robot Framework (preferred)
  Playwright/Selenium/Cypress.
• Automate testing for: REST APIs GraphQL APIs Event-driven systems Streaming systems Webhooks Microservices MFE (Micro Frontend) architectures.
• Build reusable automation libraries, utilities, and AI-assisted testing workflows.
• Integrate automation into CI/CD pipelines and quality gates.

• Validate RAG architectures including Chunking strategies Embedding quality Retrieval accuracy Re-ranking Vector search relevance
• Work with vector databases such as:
  Pinecone Weaviate ChromaDB Qdrant FAISS
• Build or validate AI agents leveraging:
  Lang Chain, Lang Graph, CrewAI, Auto Gen, Semantic Kernel OpenAI SDKs
• Validate AI workflows involving:
  Tool calling Function calling Agent memory Agent planning/execution Multi-modal AI systems Structured outputs

• Build and maintain quality workflows integrated with:
  Git Hub Actions Jenkins Git Lab CI/CD Azure Dev Ops
• Work with Docker and Kubernetes environments.
• Perform cloud-based testing and deployments across AWS/Azure/OCI/GCP.
• Validate distributed systems reliability and resiliency.
• Monitor AI system behaviors using observability platforms/logging/tracing tools.
• Contribute to shift-left and quality engineering best practices.
