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 general 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 you00ll 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.
