About the role
Build QA processes from scratch by establishing testing standards for a product team that doesn't yet have dedicated QA, embedding quality practices into sprint planning, backlog refinement, and the development lifecycle. Own quality across the product: take end-to-end responsibility for testing our Site Intelligence product, from customer-facing tools to the internal systems that support them. Build test automation: assess the current state of testing, select the tools and technologies best suited to the product, and design and implement a scalable test automation strategy and framework aligned with existing company-wide QA approaches. Lead backend API and UI test automation by designing, building, and maintaining automated test suites for backend microservices, asynchronous data workflows, and public and internal APIs. Validate complex cross-system integrations by testing data flows across multiple connected systems, including crawlers, internal configuration tools, metadata engines, and reporting APIs, to identify edge cases before production releases. Integrate automated testing into CI/CD pipelines by partnering with infrastructure teams to establish staging and release candidate environments and embed quality checks into the deployment process. Collaborate closely with product managers, engineers, tech leads, and cross-functional teams to align the testing strategy with product goals and engineering priorities - integrating QA within an established team of developers that owns testing on their side, without slowing down delivery.

About you
