About the role 

We want someone who takes ownership: a proactive team member who understands our business goals, anticipates risks, suggests improvements, and ensures our digital products deliver exceptional value to users. If you don’t just test features but think about how they fit into the bigger picture, we want you. 

Key Responsibilities  

• Take full ownership of the quality of assigned products/features, not just finding bugs, but ensuring the overall user experience is smooth, intuitive, and aligned with business goals. 

• Think beyond the acceptance criteria: identify edge cases, missed scenarios, and potential real-world user behaviors. 

• Continuously monitor and analyze product flows (forms, funnels, registration, email journeys, etc.) and proactively highlight risks, bottlenecks, or UX issues before they escalate. 

• Suggest improvements to processes, user experience, documentation, and testing methodology. 

• Manually test web applications for functionality, usability, accessibility, and performance. 

• Create, update, and maintain test cases and testing documentation with a focus on clarity, completeness, and business value. 

• Ensure cross-browser compatibility and responsiveness across devices. 

• Test REST APIs and validate system integrations. 

• Collaborate proactively with developers, designers, product managers, and stakeholders to deeply understand product requirements and challenge unclear or incomplete logic. 

• Document issues clearly with actionable steps and proper context. 

• Maintain an always-on mindset: continuously monitor critical flows and provide feedback on improvements to quality, automation potential, or product reliability. 

• Contribute ideas to improve QA processes, tools, and approaches, helping the entire team deliver better and faster. 

Basic Qualifications 

• 3+ years of experience in manual testing web applications. 

• Strong understanding of QA methodologies, SDLC, and best practices in modern web development. 

• Good knowledge of JavaScript, HTML, CSS, and how web applications work under the hood. 

• Experience with bug-tracking tools such as Jira, Bugzilla, or similar. 

• Ability to analyze complex systems, think critically, and propose improvements, not just report issues. 

• Excellent communication skills and the confidence to challenge assumptions when necessary. 

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

Would be beneficial 

• Knowledge of MySQL optimization and WordPress database structure 

• Familiarity with Linux server environments and deployment processes 

• Experience with Laravel framework or Roots ecosystem (Bedrock, Sage, Trellis) 

• Experience with WordPress Multisite networks 

• Experience with Docker, CI/CD pipelines 

• Previous work on high-traffic WordPress sites 

• Experience with advanced caching solutions (Redis, Varnish, etc.) 

• Work with WordPress CLI (WP-CLI) for deployment and maintenance tasks
