Senior Test Automation Engineer

We are looking for a Senior Test Automation Engineer to join our Quality Engineering team and help us raise the bar on software quality across a global HR and payroll platform, a complex, distributed B2B SaaS platform. You will work closely with product owners from the earliest stages of development, own automation coverage across frontend, backend, and microservice boundaries, and play a hands-on role in evolving our testing infrastructure. What You’ll Do - Design, implement, and maintain automated E2E test suites covering UI, API, and third-party integration points. - Champion shift-left practices by embedding in sprint planning, story refinement, and design reviews to catch quality risks early. - Own regression testing, exploratory testing, and production validation across critical product workflows. - Write type-safe, schema-validated test code using TypeScript and Zod to minimize false positives and improve maintainability. - Build and maintain E2E and component tests with Playwright/Cypress, covering critical user flows and edge cases. - Integrate automated test suites into CI/CD pipelines to ensure fast, reliable feedback to developers. - Design and execute API test coverage using Postman and REST-assured. - Test event-driven and asynchronous workflows across microservice boundaries. - Identify gaps in coverage, prioritize them against risk, and drive resolution with a pragmatic mindset. - Collaborate in a QA team, contributing to shared standards, tooling decisions, and documentation. - Identify, track, and triage bugs using tools like Jira and Xray. - Mentor engineers on testability and release confidence. What You'll Bring - 4+ years of hands-on test automation experience in production software environments. - Strong TypeScript skills: you write test code that is clean, readable, and easy to extend. - Solid experience with Playwright or Cypress for E2E, both UI and API testing. - Familiarity with Zod or other runtime schema-validation libraries. - Hands-on expertise across the whole STLC, including testing patterns and architectures (e.g., Page Object Model, fixtures and factories, data-driven testing) and end-to-end test design strategies. - API testing expertise with Postman and/or REST-assured across RESTful and event-driven interfaces. - Hands-on experience with bug tracking and test management tools (Jira, Xray, or equivalent). - Practical experience testing microservice architectures, including service isolation strategies. - Comfortable working within Agile/Scrum ceremonies (sprint planning, refinement, design reviews) and collaborating directly with product owners and developers. - Ability to test third-party integration points and design robust strategies around external dependencies. - Excellent problem-solving and debugging skills, with the ability to write clear, reproducible, and well-prioritized bug reports. - Experience mentoring or coaching engineers on testing practices and quality ownership. - Familiarity with current AI-assisted development tools (e.g., GitHub Copilot, Claude, Cursor) and sound judgment on where AI fits in the testing workflow, accelerating delivery without compromising rigor or ownership. - A proactive, detail-oriented mindset that thrives in fast-paced, high-ownership environments. - Bilingual English/Spanish (written and verbal). Nice to have - Experience in payroll, fintech, or other compliance-heavy domains. - Understanding of contract testing concepts and tools. - Exposure to security and privacy testing (e.g., GDPR, SOC 2 readiness). - Familiarity with performance and load testing tools (e.g., k6, JMeter, Gatling). - Experience with observability or production monitoring tools (Datadog, Grafana, Sentry, or equivalent). - Comfort working in distributed, asynchronous teams across multiple time zones. - Familiarity with Jenkins configuration and pipeline authoring.
