We are seeking a Senior Test Automation Engineer to drive quality across APIs, web UIs, and performance-critical systems.

In this role, you will design and maintain robust automated test suites, execute performance testing in CI pipelines, and ensure that quality standards align with real business impact. You will work closely with engineering teams to shape testing strategy from architecture and service boundaries, leveraging modern tools and AI-assisted approaches to deliver reliable, scalable software.

Responsibilities

Design, build, and maintain automated test suites for APIs (sync and async) and web UI using TypeScript and modern E2E frameworks
Execute and evolve performance testing within CI pipelines, analyzing results against application and infrastructure metrics
Correlate load results with CPU, memory, saturation, queue depth, and latency histograms to identify bottlenecks
Integrate and maintain automated tests in CI platforms, managing failing builds, artifacts, flaky tests, and quality gates




Approach testing from architecture and service boundaries rather than relying solely on UI script lists
Report defects clearly with expected vs vigente results, supporting evidence, and severity aligned to business impact
Leverage AI-assisted tooling to accelerate test creation and coverage
Collaborate with development and infrastructure teams to embed quality throughout the delivery lifecycle
Continuously improve test reliability, execution speed, and maintainability across the automation suite

Requirements

Hands-on experience in software testing, including 3+ years of hands-on test automation and 1+ years of hands-on performance testing
Proficiency in test automation for APIs and web UI using TypeScript and modern E2E frameworks (Playwright preferred), including sync and async APIs
Demonstrable performance testing background, including within CI
Skills in correlating load results with application and infrastructure metrics such as CPU, memory, saturation, queue
