Job Description
At AlertMedia, we help organizations protect their people, operations, and brand.
Requirements
- You’re passionate about software quality and creating efficient, scalable testing processes. You enjoy understanding how applications are built and how customers use them in the real world. You have a strong attention to detail, think critically about risk and user impact, and thrive in fast-paced, collaborative environments. You have experience testing AI features in customer-facing products. You're comfortable testing systems that don't return the same answer twice, and you know how to measure quality without a correct output to assert against.
- You embrace automation and modern engineering practices, including AI-powered tools and workflows that improve testing efficiency, accelerate development, and enhance product quality. You believe quality is a shared responsibility and should be built into the product from day one.
- Most importantly, you enjoy working cross-functionally with Engineering, Product, and Customer Success teams to deliver meaningful outcomes for customers.
- 5+ years of experience in QA, SDET, or software testing roles
- Experience with LLM evaluation techniques — curated case sets, rubric or model-graded scoring, regression baselines
- Hands-on experience testing agentic systems (tool/function calling, multi-step workflows, MCP or similar integrations) and the failure modes they introduce, including prompt injection through untrusted content
- Experience mentoring teammates or serving as a QA thought partner preferred
- Strong understanding of API, integration, and distributed systems testing
- Experience designing scalable, maintainable automation frameworks and test strategies for modern web applications using tools such as Selenium, Cypress, Playwright, or Gherkin
- UI automation testing experience using Python or JavaScript
- Familiarity with CI/CD workflows and tools such as Git, Jenkins, or similar platforms
- Familiarity working with SQL and/or NoSQL databases
- Experience using AI-powered engineering tools such as Codex, Claude, Cursor, or similar technologies to improve productivity and testing workflows
- Strong communication and collaboration skills with the ability to work cross-functionally in a fast-paced environment
- English proficiency (written and verbal) required
- Bachelor’s degree preferred
- Location: This role can be fully remote within Mexico or hybrid (1–2 days/week) in our Reforma-area office in Mexico City, where you’ll collaborate closely with our engineering team.
- Sponsorship: AlertMedia does not sponsor candidates. Must have the legal right to work in Mexico without sponsorship now and in the future.
