Playwright Engineer (Contract)

Your tasks

Responsibillities

• Define and execute end to end test strategies covering UI workflows, backend APIs, integrations and agentic interfaces.

• Test conversational and agentic behaviour including multi turn 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 behaviour and safe failure, while recognising 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, authorisation, validation, error handling, idempotency, rate limits and downstream failures.

• Test UI behaviour 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.

• Provide an evidence based release recommendation, including known limitations, residual risks and areas requiring monitoring.

• Partner with product owners, business users, architects, engineers and GenAI specialists to define the problem, target user journeys and expected business outcomes.

• Analyse proposed GenAI use cases and determine where deterministic application logic, retrieval, workflow orchestration, tool using agents or human approval should be used.

Requirements

Core Requirements

• 5 to 8 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.

• Experience with Git, pull requests, CI/CD pipelines, test reporting and defect management tools.

• Understanding of security and privacy testing fundamentals, including access control, sensitive data handling, input validation and auditability.

• Strong stakeholder communication and the confidence to challenge weak designs, vague expected outcomes and premature release decisions.
