Why You'll Love This Role

You will perform manual testing for exploratory, regression, and end-to-end scenarios when needed.

You will review and analyze business and technical requirements to define appropriate test coverage Collaborate closely with developers, product managers, and other stakeholders to ensure quality across the SDLC.

You will build API and service-layer test automation from scratch; test APIs both manually (via tools like Postman) and through automated scripts.

You will test internally built LLMs and AI-driven features for accuracy, consistency, and edge case behavior.

Evaluate third-party AI tools and services integrated into the Newsela platform.
