[Hiring] QA Specialist @Ruby Labs

Role Description

Ruby Labs builds and scales multiple D2C subscription products across health, education, and entertainment. Quality is not a gate at the end of our process; it is woven into every sprint, every release, and every decision.

We are looking for a Mid-Level QA Specialist who takes genuine ownership of product quality. In this role, you will work closely with engineers and product managers to:

• Test web applications and native Android and iOS applications.
• Design and execute comprehensive test plans for new features, covering functional, regression, edge cases, and end-to-end scenarios using Playwright and TypeScript.
• Perform exploratory and risk-based testing to uncover issues that scripted tests miss.
• Act as the first line of investigation for customer complaints – reproduce the issue, reconstruct the user's session from available data, and determine whether it's a product defect, a data issue, or a third-party failure before escalating to engineering.
• Integrate automated tests into CI/CD pipelines to enforce quality gates on every merge.
• Validate backend APIs using Postman or equivalent tools.
• Use SQL queries to verify data correctness and integrity at the database (Postgres) level.
• Validate complete user flows across every system they touch – the product itself, Mixpanel analytics, the payment provider's dashboard, Customer.io email data, and the database.
• Document bugs with precision – clear reproduction steps, environment and build details, logs, and screenshots.
• Prioritize issues by severity and impact, communicating urgently when critical paths are affected.

Qualifications

• 3+ years of hands-on QA experience in a product or SaaS environment.
• Strong experience with test automation – Playwright + TypeScript strongly preferred.
• Solid experience with API testing using Postman or a similar tool.
• Working knowledge of SQL for data validation and backend verification.
• Experience testing subscription funnels, checkout flows, or payment systems.
• Excellent attention to detail and a methodical, structured approach to testing.
• Strong ownership mindset – you do not wait to be told something is broken.
• Comfortable working remotely in a fast-paced, high-expectation environment.
• Fluent English, written and spoken.

Requirements

• Experience with performance or load testing tools (k6, Locust, or similar) - Nice to have.
• Familiarity with CI/CD pipelines, particularly GitHub Actions - Nice to have.
• Experience with monitoring and observability tools such as Sentry or Better Stack - Nice to have.
• Background in fintech, subscription, or health/wellness digital products - Nice to have.
• ISTQB or equivalent QA certification - Nice to have.

Benefits

• Remote Work Environment: Embrace the freedom to work from anywhere, anytime, promoting a healthy work-life balance.
• Unlimited PTO: Enjoy unlimited paid time off to recharge and prioritize your well-being, without counting days.
• Paid National Holidays: Celebrate and relax on national holidays with paid time off to unwind and recharge.
• Company-provided MacBook: Experience seamless productivity with top-notch Apple MacBooks provided to all employees who need them.
• Flexible Independent Contractor Agreement: Unlock the benefits of flexibility, autonomy, and entrepreneurial opportunities. Benefit from tax advantages, networking opportunities, reduced employment obligations, and the freedom to work from anywhere.
