streaming\nand data-warehouse workloads using technologies such as Spark, Kafka, Hadoop, Hive, HDFS, and Delta Lake.\nAutomate data-quality validation using Python, PySpark, Pytest.\nValidate ingestion, transformation, schema evolution, partitioning, reconciliation, completeness, accuracy, freshness, and business rules.\nTest distributed microservices, REST and GraphQL APIs, and event-driven architectures.\nBuild API, integration, component, and consumer-driven contract tests using tools such as Postman/Newman, REST Assured, or equivalent frameworks.\nValidate authentication, authorization, backward compatibility, retries, timeouts, circuit breakers, data consistency, idempotency, failure recovery, and service resilience.\nEvaluate scalability, performance, and fault tolerance under production-like traffic and data volumes.\nWeb and Browser Automation\nDesign and maintain\nscalable test frameworks using Playwright and Cypress.\nDevelop reliable end-to-end, API, integration, visual-regression, and accessibility test coverage.\nUse Playwright capabilities such as browser isolation, fixtures, auto-waiting assertions, network interception, API testing, tracing, screenshots, parallel execution, and test sharding.\nTest dynamic, data-driven interfaces and validate consistency across the browser, APIs, microservices, and data stores.\nImprove automation reliability through stable locators, deterministic test data, service virtualization, API mocking, and effective failure diagnostics.\nAgentic AI and LLM Testing\nDefine evaluation strategies for LLM applications, RAG systems, AI copilots, tool-using agents, and multi-agent workflows.\nBuild evaluation datasets from curated, production-derived, edge-case, and adversarial scenarios.\nMeasure task completion, accuracy, groundedness, retrieval quality, instruction following, tool selection, structured outputs, state management, and workflow completion.\nTest AI systems for prompt injection, jailbreaks, sensitive-data leakage, hallucination, insecure output handling, excessive agency, and unsafe tool use.\nValidate guardrails, least-privilege access, sandboxing, rate limits, human approvals, and recovery from failed or unexpected actions.\nImplement trace-based evaluation and continuous quality gates for agent decisions, tool calls, latency, errors, token usage, and cost.\nUse Playwright to test browser-capable AI agents, including navigation, form interaction, permissions, approval checkpoints, and error recovery.\n\nRequired Qualifications:\n\nBachelor's or Master's degree in Computer Science, Engineering, or a related field, or equivalent practical experience.\n10+ years of experience in software quality engineering, test automation, or software development, including senior technical leadership.\nStrong experience testing distributed data pipelines, microservices, APIs, or event-driven systems.\nHands-on experience with Spark, Kafka, Hadoop, Hive, or modern cloud-data platforms.\nAdvanced programming and automation skills in Python, and JavaScript/TypeScript.\nStrong browser-automation experience with Playwright or Cypress, including framework design, API testing, parallel execution, and CI integration.\nExperience with API contracts, service virtualization, distributed workflows, authentication, and failure handling.\nExperience with CI/CD
