mportant IT company At the Latin American level, growth requires:

We are looking for a Senior SDET / AI Quality Engineer to design, build, and evolve automation strategies for modern software platforms, including AI-powered and agentic applications. This role requires a strong engineering mindset, deep automation expertise, and the ability to drive quality across the entire software development lifecycle.

Possess practical experience with automation frameworks, API testing, CI/CD quality practices, and emerging AI validation techniques. You will collaborate with engineering, product, and AI teams to ensure the reliability, correctness, security, and scalability of complex systems.

Responsibilities:

• Design, develop, and maintain scalable automation frameworks for UI, API, integration, and end-to-end testing.

• Build automation solutions using modern testing frameworks and programming languages.

• Own quality engineering practices across the SDLC, from requirements validation to production monitoring.

• Develop automated test strategies for AI-powered applications, including agentic workflows, tool usage, decision paths, and failure scenarios.

• Validate AI system behavior across deterministic and non-deterministic scenarios.

• Create test approaches for LLM-based systems, including prompt validation, response quality evaluation, regression testing, and guardrail verification.

• Integrate automated testing into CI/CD pipelines and establish quality gates.

• Collaborate with developers and architects to improve system reliability, observability, and maintainability.

• Identify gaps in testing processes and proactively introduce improvements.

• Mentor engineers and promote automation and quality engineering best practices.

Must-Have Qualifications:

• 5+ years of experience in Software Development Engineer in Test (SDET), Quality Engineering, or Automation Engineering roles.

• Strong automation engineering background with hands-on experience designing and maintaining test frameworks.

• Advanced experience with Playwright for UI automation and end-to-end testing.

• Strong API testing experience including REST APIs, integrations, contracts, and service validation.

• Experience creating automation pipelines integrated with CI/CD platforms.

• Strong programming skills in Java, Python, TypeScript, or similar languages.

• Experience building maintainable automation code using software engineering best practices.

• Experience testing distributed systems and complex application workflows.

• Experience testing AI-powered or agentic applications, including:

• Workflow correctness validation.

• Agent decision flows.

• Tool/function calling validation.

• Failure recovery scenarios.

• Safety and reliability testing.

• Strong analytical skills with the ability to troubleshoot complex technical issues.

• Ownership mindset with the ability to independently drive quality initiatives.

Preferred Qualifications

• Experience with LLM evaluation frameworks and AI quality methodologies.

• Experience validating prompts, workflows, AI responses, and model behavior.

• Knowledge of AI guardrails, safety testing, and responsible AI practices.

• Experience testing retrieval-based systems (RAG), embeddings, vector search, and knowledge-grounded responses.

• Experience designing tests for non-deterministic systems.

• Exposure to performance, scalability, resilience, and chaos testing.

• Experience with observability testing, including logs, metrics, traces, and monitoring strategies.

• Experience with service virtualization, mocks, synthetic data generation, and test environment management.

• Experience testing cloud-native architectures and distributed/event-driven systems.

• Familiarity with platforms such as AWS, Azure, or GCP.

• Experience mentoring engineers and establishing QE standards across teams.
