Test Automation Engineer

HALO's LatAm Test Automation Engineers bring senior-level QA expertise across modern web applications, backend systems, and AI-integrated testing workflows. Their framework design spans the full stack — from frontend testing in React, Next.js, and Angular to API and integration testing against Node.js, Python/FastAPI, and Java/Spring backends. Database fluency across PostgreSQL, MongoDB, and MariaDB ensures comprehensive data validation at every application layer. Grounded in software craftsmanship principles, they champion Test-Driven Development and Domain-Driven Design while maintaining clean, maintainable automation suites that teams can build on over time. What distinguishes this talent profile is the integration of AI capabilities into the testing workflow — leveraging OpenAI APIs, Retrieval Augmented Generation, and advanced prompting techniques to build intelligent test generation, data synthesis, and anomaly detection systems. For organizations looking to modernize quality assurance without sacrificing reliability, these engineers bridge rigorous testing discipline with forward-thinking automation architecture.
