We’re looking for a hands-on Quality Assurance Engineer with strong manual testing experience to ensure our products meet the highest quality standards before release.

You’ll be responsible for validating functionality, UX/UI consistency, edge cases, and overall product stability across web and mobile environments. You’ll work closely with product, design, and engineering teams and play a key role in making sure features are ready for release from a quality standpoint. Over time, this role offers an opportunity to grow beyond pure QA and take on more responsibility around coordination, execution, and delivery ownership.

Key Responsibilities

• Perform thorough manual QA testing across web and mobile (UI, UX, logic, edge cases, responsiveness).

• Validate product behavior against specs, designs, and expected user flows.

• Identify, document, and clearly communicate bugs and inconsistencies.

• Verify fixes and ensure issues are fully resolved before release.

• Conduct regression testing for new features and production hotfixes.

• Maintain structured bug reports and testing documentation.

• Ensure consistent quality across browsers, devices, and screen sizes.

• Participate in release readiness checks and quality sign-offs.

Qualifications

• 2–4 years of experience in manual QA for web or SaaS products.

• Strong attention to detail with a solid understanding of UX/UI best practices.

• Experience testing complex user flows and edge cases.

• Basic understanding of:

  • Browser developer tools

  • APIs (request/response basics)

  • Mobile web testing

• Familiarity with QA and tracking tools (e.g., Notion, JIRA, Trello, plane.so).

• Clear written and verbal communication, especially when describing issues.

• Strong sense of ownership and accountability for quality.

Nice to have

• Interest in growing into a broader role with responsibility for coordination and delivery.

• Early experience helping track tasks, follow up on fixes, or support release planning.

• Familiarity with agile or sprint-based workflows.

• Experience working closely with designers and engineers throughout feature development.

• Exposure to consumer-facing products or subscription-based SaaS.

• Experience testing feature flags, experiments, or A/B tests.
