QA Engineer

Linnworks is the global leader in the eCommerce automation sector, focused on giving clients back their time to grow and lead their brands. They are seeking a QA Engineer responsible for ensuring features and fixes behave as intended across web UI and APIs, providing hands-on testing and clear feedback to facilitate confident deployments.

Responsibilities:

• Plan, execute, and document manual test cases for web UI features and cross-cutting user journeys
• Validate that the UI correctly reflects and handles responses and errors from underlying APIs
• Perform exploratory testing to uncover edge cases, usability issues, and unexpected behaviour
• Maintain lightweight smoke and regression scenarios for critical end-to-end flows
• Design and execute manual API tests using tools such as Postman, curl, or similar
• Validate request and response structures, status codes, error handling, and data integrity
• Chain API calls to simulate realistic workflows and ensure correct behaviour independent of the UI
• Identify gaps in API behaviour, validation, and documentation based on real-world usage patterns
• Participate in refinement, planning, and design discussions to surface testability and quality concerns early, particularly around API contracts and UI/API interactions
• Collaborate with engineers to clarify expected behaviour, edge cases, and acceptance criteria for both UI and API changes
• Provide clear, concise feedback on risks, issues, and test results to engineers, Product, and the QA Team Lead
• Help the team make sensible trade-offs when time, scope, and quality risk are in tension by explaining the impact of different options
• Translate requirements, user flows, and API specifications into structured test conditions and scenarios
• Prioritise testing effort based on risk, impact, and customer usage, not blanket coverage
• Reproduce, investigate, and document issues with clear steps, including failing UI flows and/or API requests and responses
• Verify fixes at both the API and UI layer, checking for regressions before changes are released
• Maintain and organise reusable API request collections (for example, in Postman) to support consistent testing
• Suggest pragmatic opportunities where small amounts of automation or scripted checks can reduce repetitive manual work or speed up feedback loops
• Use available tools (logs, monitoring, feature flags, test data management) to make UI and API testing more effective

Requirements:

• Solid experience in a manual QA or software testing role, ideally in a SaaS or product environment
• Strong ability to design and execute tests for both web UIs and APIs
• Comfortable using tools such as Postman and curl, including working with authentication, headers, and payloads
• Comfortable working with issue trackers, pre-production environments, and basic debugging tools (for example, browser dev tools, logs)
• Clear, direct written and verbal communication when describing defects, risks, and test outcomes
• Any experience with test automation (UI or API) is a bonus, but not essential
