QA Manual Tester

We’re always looking for talented people who want to grow with us and be part of what we’re building next!

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
