QA Engineer | Freelance Remote Contract (UK candidates only) Outside IR35 12 months About Elsewhen: Elsewhen, a London-based consultancy, designs and builds technology solutions for clients like Spotify, Google, Inmarsat, and Zego. Over the past decade, we have built a workplace prioritising impact, drive, and friendliness. We value outcomes over hours and agility over rigid processes. Work Environment: Remote-first setup: Fully remote work with the option to use a WeWork membership for those who prefer occasional office access. Join our team: https://www.elsewhen.com . Role: We are building an AI-powered knowledge platform that lets users ask natural language questions and get structured answers from complex data graphs. Your job is to make sure it works, is accurate and can be trusted. You’ll be responsible for validating how we interpret user intent, how we translate that into graph queries, and how we return meaningful, correct results. This is not a "click around and raise bugs" role. You'll be hands-on with data, APIs, automation, and AI behaviour. You'll work closely with engineers, data, AI/LLM specialists, and product management to define what "correct" looks like, then prove it at speed and at scale. What You’ll Do: Test natural language-to-graph behaviour Verify that a user's question is translated into the correct graph query Check that the answer returned is consistent, relevant, and complete Challenge ambiguity and edge cases in user intent Validate data accuracy Confirm that entities, relationships, and metadata in the graph are correct Spot broken or missing links in the knowledge graph Raise and track data quality issues with engineering / data teams Build and maintain automated tests Design and implement automated test suites for UI, API, and graph query flows Use Python (Pytest) / Selenium or similar to cover high-value user journeys Contribute to a shared automation framework and improve test reliability over time Test APIs and system integration
