Job Description

Why You'll Love This Role:

As a Senior Full-Stack QualityEngineer, you will be a critical force in ensuring that mission is delivered through reliable, high-quality software. You will work alongside talented product engineers to test complex front-end applications powered by cloud-based back-end services, internal LLMs, and third-party AI tools. The ideal candidate will have strong experience in test automation, API validation, manual testing, and performance testing, with a proactive mindset and excellent organizational skills. This role requires someone who can deeply understand business and technical requirements and translate them into effective test strategies.

What You'll Be Doing:

• You will own quality end-to-end: from story acceptance criteria all the way to production health monitoring.

• 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.

About You:

• 7+ years of software testing and quality assurance experience in a professional engineering environment.

• 4+ years building automated test frameworks and scripts using TypeScript, JavaScript, or Python.

• 4 + years of hands-on experience with WebdriverIO and/or Playwright.

• 4+ years working in an Agile Scrum team.

• Demonstrated experience across the full spectrum of testing types: manual, exploratory, regression, integration, API/services, and database testing.

• Experience testing both web applications and mobile apps.

• Hands-on experience with AI coding assistants (e.g., Claude Code, GitHub Copilot) as part of your daily workflow.

• Strong written and verbal communication skills — you can explain a bug to a developer and a risk to a product manager equally well.

• Prior experience in EdTech or consumer-facing SaaS products.

All offers of employment are contingent upon the successful completion of a background check as part of our pre-employment process.
