About the role

We're looking for a QA engineer who takes ownership of quality, not just test execution. You understand the business goals behind a feature, anticipate risks before they reach users, and push back when requirements are unclear. If you see quality as something you build into a product, not something you check at the end, this role is for you.

Key Responsibilities 

• Own the quality of assigned products and features end to end: functionality, usability, and fit with business goals

• Go beyond acceptance criteria to find edge cases, missed scenarios, and real-world user behaviours

• Test and monitor critical flows (registration, forms, funnels, payments, email journeys) and flag risks before they escalate

• Perform manual testing of web applications for functionality, usability, accessibility, and performance across browsers and devices

• Test REST APIs and validate integrations with internal and third-party systems

• Validate analytics and tracking (e.g. GA4, GTM events) on key journeys

• Create and maintain test plans, test cases, and regression suites focused on clarity and business risk

• Report issues with clear reproduction steps, context, and impact

• Work closely with developers, designers, and product managers to clarify requirements and challenge incomplete logic early

• Identify automation opportunities and contribute to building automated regression coverage

• Improve QA processes, tools, and release practices across the team

Basic Qualifications

• 3+ years of experience testing web applications

• Strong understanding of QA methodologies, test design techniques, and the SDLC

• Good knowledge of HTML, CSS, JavaScript, and how web applications work under the hood (HTTP, cookies, caching, client vs. server)

• Confident with browser DevTools (elements, network, console, storage) for investigating issues

• Experience testing REST APIs with tools such as Postman or Insomnia

• Experience with Jira or similar bug-tracking and test management tools

• Comfortable using AI tools to speed up test design and analysis, with the judgment to verify their output

• Excellent communication skills and the confidence to challenge assumptions

• Strong attention to detail, curiosity, and a proactive mindset

Would be beneficial

• Test automation experience with Playwright or Cypress 

• Performance testing basics (Lighthouse, Core Web Vitals, k6 or JMeter) 

• Experience testing WordPress sites, including Multisite and high-traffic sites 

• Understanding of caching layers (Redis, Varnish, CDN) sufficient to reproduce and isolate cache-related issues 

• Ability to set up local or test environments with Docker or WP-CLI 

• Familiarity with CI/CD pipelines and how QA fits into release processes 

• Experience testing event, ticketing, or payment flows
