Sr. QA Engineer (Costa Rica)

What You'll Do8

• Lead testing strategy for assigned feature areas, set expectations for unit, component, and service tests that engineering teams own, and cover high-risk flows with end-to-end automation.
• Build, extend, and maintain automated test suites, then wire them into CI/CD pipelines so each change returns fast and dependable quality feedback.
• Coach developers on test design through pairing, code reviews, and workshops that make shift-left testing part of daily delivery.
• Turn business and technical risks into test plans, acceptance criteria, and documentation that product and engineering teams keep current.
• Write and refine quality standards, policies, and risk-based testing guides that match product needs and compliance rules.
• Track defect trends, coverage gaps, and flaky tests, then use those signals to expose systemic issues and guide improvement work.
• Brief engineering and product leaders on quality posture, risks, and tradeoffs, and avoid becoming a release bottleneck.
• Mentor junior QA staff and engineers on modern testing methods, observability-driven checks, and AI-assisted testing practices.

Requirements7

• 5+ years in software quality engineering, SDET work, or a comparable role centered on test automation and helping engineering teams own quality.
• Hands-on skill in one modern language such as TypeScript, JavaScript, or Python.
• Experience with current test frameworks such as WebdriverIO, Playwright, Cypress, Appium, or API and contract testing tools.
• Track record of adding automated tests and quality gates to CI/CD pipelines using GitHub Actions, GitLab CI, Jenkins, or a similar system.
• Solid grasp of shift-left and DevOps methods, including developer-owned testing, trunk-based development, and continuous delivery.
• Ability to operate inside an independent Quality function while forming collaborative relationships with engineering groups.
• Strong communication and facilitation skills, with the ability to influence peers without authority, lead discussions, and align teams on quality goals.

Preferred Qualifications3

• Experience with observability tools and production signals used to shape testing strategy
• Familiarity with AI-assisted testing tools or LLM-based features for test generation, analysis, or automation
• Background in regulated or high-compliance settings where risk management and traceability matter

Who Should Apply

The ideal candidate brings 5+ years of QA or SDET experience, writes test automation in TypeScript, JavaScript, or Python, and has wired suites into CI/CD pipelines. You coach developers on shift-left testing and turn risk into clear test strategy. This contractor role suits a senior QA engineer based in Costa Rica who wants to shape quality without acting as a release gatekeeper.
