About The Role

We’re building and scaling a high-growth D2C product in the LegalTech / Utilities space and are looking for a QA Engineer who takes real ownership of product quality.

This is a hands-on, manual QA–first role in a fast-moving environment where features ship often, experiments run continuously, and quality cannot be an afterthought. You’ll work closely with Product and Engineering to ensure that what reaches users is stable, reliable, and works as expected across browsers, devices, and real-world scenarios.

We’re not looking for someone who only executes test cases. We’re looking for a quality owner — someone who thinks in user journeys, spots risks early, understands how systems break in production, and proactively raises issues before they impact customers.

This is not a checkbox or 9–5 role. The pace is high, expectations are clear, and your work will have direct impact on user experience, conversion, and trust in the product.
