Formación

• Bachelor’s degree in Computer Science, Engineering, or related field, or equivalent practical experience.

Responsabilidades

• Own cross-team quality strategy, automation architecture, and risk-based coverage for distributed, multi-tenant SaaS services, APIs, SDKs, and integration surfaces.
• Design and implement reusable automation frameworks, test libraries, service simulators, and deterministic test-data capabilities that support parallel execution and maintainable coverage.
• Embed automated unit, integration, contract, API, end-to-end, and regression testing into CI/CD pipelines; establish actionable quality gates and reduce flaky tests and feedback time.
• Lead performance and scalability validation through workload modeling, load, stress, spike, soak, and capacity testing; assess latency, throughput, resource consumption, and tenant fairness against agreed service objectives.
• Define robustness and resilience testing for dependency failures, network disruption, retries, timeouts, recovery, concurrency, and partial outages; validate graceful degradation and fail‑open or fail‑closed behavior against approved policies.
• Partner with Security and Architecture to validate identity, delegated authorization, tenant isolation, evidence integrity, replay, continuous authentication, and content provenance, including negative and boundary scenarios.
• Establish production-representative test environments and synthetic or approved de‑identified data practices; validate upgrades, backward compatibility, migrations, and rollback readiness.
• Lead complex defect investigations using logs, traces, metrics, and reproducible experiments; drive cross-team root‑cause analysis and systemic prevention.
• Define quality reporting that makes coverage, escaped defects, automation reliability, performance risks, and release readiness transparent without relying solely on test pass rates.
• Mentor quality and software engineers, lead test‑design reviews, and create reusable guidance that strengthens quality ownership across development teams.
