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
