• Hands-on ability with API tools and automation frameworks such as Postman, REST Assured, pytest, Playwright, Cypress, Selenium.

Responsibilities

• Define and execute end to end test strategies covering UI workflows, backend APIs, integrations and agentic interfaces.
• Test conversational and agentic behavior including multiturn context, tool selection, tool inputs/outputs and state transitions.
• Validate GenAI responses for task completion, grounding, relevance, consistency, citation behavior and safe failure.
• Perform functional, integration, regression, exploratory, negative, resilience and basic performance testing.
• Design API tests for contracts, authentication, authorization, validation, error handling, idempotency, rate limits and downstream failures.
• Test UI behavior across browsers and realistic user journeys, including loading states and clear error communication.
• Create and maintain test data, reusable test scenarios and traceable evidence for governance.
• Use logs, traces, payloads and observability tools to isolate defects across layers.
• Automate tests that reduce cycle time and production risk; exclude unstable or low-value scenarios.
• Communicate defects and quality risks clearly to engineers, product owners and security teams.

Responsibilities

• Define and execute end to end test strategies covering UI workflows, backend APIs, integrations and agentic interfaces.
• Test conversational and agentic behavior include multiturn context, tool selection, tool inputs and outputs, state transitions, retries, timeouts, handoffs, approvals and recovery from partial failure.
• Validate GenAI responses for task completion, grounding, relevance, consistency, citation behavior and safe failure, while recognizing that outputs can be non-deterministic.
• Perform functional, integration, regression, exploratory, negative, resilience and basic performance testing across application layers.
• Design API tests for contracts, authentication, authorization, validation, error handling, idempotency, rate limits and downstream failures.
• Test UI behavior across browsers and realistic user journeys, including loading states, interrupted sessions, feedback capture, accessibility basics and clear error communication.
• Create and maintain test data, reusable test scenarios and traceable evidence suitable for enterprise release governance.
• Use logs, traces, request and response payloads and observability tools to isolate defects and distinguish application, model, data, integration and platform issues.
• Automate the tests that materially reduce cycle time, manual effort or production risk, and keep unstable or low value scenarios out of the automation suite.
• Communicate defects and quality risks clearly to engineers, product owners, GenAI specialists, security teams and business stakeholders

Requirements

• Bachelor Degree with 6 years of experience in software quality engineering, test engineering or a similar hands-on role covering complex applications.
• Strong experience testing web user interfaces, backend services and REST APIs.
• Hands on ability with API tools and automation frameworks such as Postman, REST Assured, pytest, Playwright, Cypress, Selenium or equivalent.
• Working knowledge of Java, Python, JavaScript or TypeScript sufficient to build, review and troubleshoot test automation.
• Strong test analysis skills, including requirements review, risk assessment, boundary analysis, negative testing and traceability.
• Experience validating distributed systems and integrations, including asynchronous processing, queues, batch jobs and downstream dependencies.
• Ability to inspect logs, traces, network calls, payloads and database records to identify the actual failure point.

We regret that only shortlisted candidates will be contacted.
