About the Role
Guac is looking for a QA Engineer to own quality and testing across its web and mobile products. This is an initial 3–4 month independent contractor engagement, with the potential to extend the contract or increase working hours.
As Guac's first dedicated QA hire, you'll establish testing practices, review new features before release, and build automated testing capabilities. You'll work across the React/Next.js web application, React Native mobile application, and backend APIs to identify defects early and maintain reliable releases. The role requires someone who can work independently, write clear test documentation, and build automated test suites from scratch.
Key Responsibilities
Review feature requirements and designs, develop thorough test plans, and execute tests before new features are released.
Own regression testing ahead of releases across the React/Next.js web application and React Native mobile application.
Write clear, reproducible bug reports and track defects through resolution.
Build and maintain an automated end-to-end test suite, progressively replacing manual regression testing with reliable automation.
Write and maintain API-level tests to validate backend integrations.
Use AI tools to accelerate test authoring, identify edge cases, and improve test coverage.
Establish and develop QA processes as Guac's first dedicated quality assurance hire.
Required Qualifications
3+ years of QA experience testing web and/or mobile applications.
Strong ability to write thorough test plans and reproducible bug reports based on requirements or designs.
Experience with test automation frameworks such as Playwright, Cypress, Detox, Maestro, or similar tools.
Previous experience building automated test suites from scratch.
Experience with API testing tools such as Postman, REST Assured, or similar platforms.
Ability to work asynchronously with minimal supervision.
Availability to overlap with core Eastern Time business hours when needed, particularly during release cycles. Core hours are 10 a.m.–6 p.m. ET.
Preferred Qualifications / Requirements
Experience with Guac's technology stack, including Playwright, Jest, Maestro, React/Next.js, and React Native.
Experience testing logistics, supply chain, grocery, or fulfillment software.
Familiarity with CI/CD pipelines and tools such as GitHub Actions or CircleCI.
Working knowledge of SQL for data validation.
Regular use of AI coding tools such as Claude, Cursor, or Copilot to improve testing workflows and delivery speed.
Salary & Benefits
This is an independent contractor engagement of approximately 20 hours per week, with an initial duration of 3–4 months and strong potential to extend the contract or expand working hours.
The position is remote and flexible, with at least partial availability during core Eastern Time business hours required. Candidates based outside the United States are welcome.
