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. Apply To This Job
