QA Lead

Walker and Sloan are partnering with a fully integrated marketing agency in London as they are keen to bring on an experienced QA Lead to the team on a full time basis.

Salary: Competitive / Negotiable

We’re working with an award-winning, fully serviced marketing agency in London who deliver creative, digital, and performance-led solutions for a wide range of clients. As part of their growth, they are looking to bring on a QA Lead to own and drive the agency’s quality assurance processes across digital projects.

As QA Lead, you will be responsible for ensuring the quality, functionality, and performance of all digital deliverables before they reach clients. From websites and landing pages to campaigns and tracking set-ups, you’ll be the last line of defence for quality — ensuring outputs are flawless and align with client expectations.

You’ll work closely with developers, designers, project managers, and the wider digital team, introducing best practices, testing frameworks, and continuous improvements to the QA process.

• Lead the QA process across all digital projects (websites, campaigns, landing pages, paid media tracking, email, etc.).
• Create and maintain QA processes, checklists, and testing documentation.
• Carry out functional, regression, cross-browser, and cross-device testing.
• Identify, document, and track bugs/issues, working with teams to resolve quickly.
• Introduce tools and frameworks to improve automation and efficiency where relevant.
• Ensure all deliverables meet accessibility standards, brand guidelines, and client requirements.
• Collaborate with account management, creative, and development teams to identify issues early in the project lifecycle.
• Mentor junior team members and promote a culture of quality across the agency.

• Proven experience in a QA role, ideally within a digital/marketing agency environment.
• Strong knowledge of web and digital testing (cross-browser, cross-device, usability).
• Hands-on experience with testing tools (e.g., BrowserStack, Selenium, Cypress, Jira, etc.).
• Familiarity with CMS platforms, ad tech, and analytics tools (e.g., GTM, GA).
• Excellent attention to detail with the ability to spot issues others miss.
• Strong communication skills to give clear, actionable feedback.
• Experience introducing QA processes or leading QA within a fast-paced environment.
• Bonus: experience with automation frameworks or managing a QA team.

• Competitive salary package (negotiable depending on experience).
• Hybrid working – 2–3 days in their London HQ.
• Opportunity to shape the QA function within a growing, award-winning agency.
• Collaborative, creative, and supportive team culture.
• Career progression and ongoing training opportunities.
