Remote - Argentina; Brazil; Chile; Colombia; Costa Rica; Mexico

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.

Please note that given the nature of the contract, this role will not be eligible to participate in company-sponsored benefits
