Ruby Labs is hiring a QA Engineer

WinTech is looking for a QA Engineer to take ownership of product quality for our high-growth direct-to-consumer platform in the LegalTech/Utilities space. This is a hands-on, manual-first role where you will ensure our frequent feature releases and continuous experiments are stable, reliable, and work as expected across all user scenarios.

What You'll Do

• Own product quality for a high-growth D2C product in LegalTech/Utilities.
• Perform hands-on manual QA in a fast-moving environment with frequent releases and continuous experiments.
• Work closely with Product and Engineering teams to ensure features are stable and work as expected across browsers, devices, and real-world scenarios.
• Execute regression testing and validate fixes independently.
• Ensure quality across environments and releases.
• Communicate bugs and findings clearly, including steps to reproduce and expected vs. actual behavior.
• Collaborate with developers and product managers to maintain high-quality standards.

What We're Looking For

• Strong understanding of modern web application architecture.
• Deep knowledge of browser behavior (cookies, sessions, localStorage, cross-tab/cross-device session handling).
• Solid understanding of authentication mechanisms (Magic Link/passwordless, OAuth/SSO).
• Experience testing subscription-based products (billing flows, access control, edge cases).
• Understanding of release cycles, regression testing, and risk-based QA.
• Experience with BrowserStack or equivalent for cross-browser, cross-OS, and mobile testing.
• Proficiency with Browser DevTools for network inspection, console error analysis, and cache/storage debugging.
• Ability to read and understand API responses (REST/JSON) and HTTP status codes.
• Manual QA–first mindset with attention to detail and edge cases.
• Ability to think in real user scenarios, not just happy paths.
• Clear, structured communication of bugs and findings.
• Proactive, ownership-driven approach to quality.

Nice to Have

• Experience with D2C SaaS products.
• Exposure to A/B testing, feature flags, or experimentation frameworks.
• Understanding of automated testing concepts.

Team & Environment

You will work closely with Product and Engineering teams in a fast-paced, high-growth environment.

Benefits & Compensation

• Remote Work Environment: Work from anywhere, anytime to promote a healthy work-life balance.
• Unlimited PTO: Recharge and prioritize your well-being without counting days.
• Paid National Holidays: Celebrate with paid time off.
• Flexible Independent Contractor Agreement: Benefit from flexibility, autonomy, tax advantages, and networking opportunities.
