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
