QA Engineer – AdTech Integrations & Validation

About

As a QA Engineer focused on Publisher Integrations, you’ll be a key member of our central Quality Assurance (QA) team, embedded within our Publisher Management (PuMa) department. Publishers are 3rd party companies who want to use specific parts of our tech stack to display our content in their own applications. Your focus will be on validating publisher implementations before go-live, supporting partners and internal teams with troubleshooting, and maintaining clear and actionable technical documentation. This role combines independent testing and debugging, communication across teams, and active involvement in keeping our integration ecosystem robust and scalable.

Your mission

• Test new publisher integrations based on contractual and technical requirements.
• Provide structured test reports with clear pass/fail criteria and guidance on required fixes.
• Act as a contact point for publisher tech teams and internal PuMa stakeholders, helping clarify requirements, troubleshoot integration issues, and guide next steps.
• Collaborate with the engineering teams behind our publisher-facing components (e.g. SDKs, widget) to align on expected behavior and known issues
• Maintain and improve our technical documentation, including walkthroughs, FAQs, code snippets, and short videos
• Interpret browser network traffic, tracking payloads, and frontend logic to identify and analyze integration errors.
• Communicate clearly and proactively: status updates, blockers, and test results should be traceable without requiring follow-ups.
• Prioritize work based on partner importance, revenue potential, integration deadlines, and customer campaign impact — jointly agreed with the PuMa team.
• Support other QA projects as needed, contributing to the broader QA function across the company.

This is what you bring along

• Strong technical understanding of how web integrations work: DOM structure, JavaScript, browser dev tools, and interpreting network requests (e.g. tracking pixels, API responses).
• Hands-on experience with manual functional testing in a web-based environment.
• Familiarity with tools like Postman, browser consoles, SQL query viewers, and reporting dashboards.
• Able to troubleshoot tracking issues and identify data inconsistencies across systems.
• Strong written and verbal communication skills, especially when translating technical findings to business stakeholders or external partners.
• Proactive and self-directed — you work independently, track your own progress, and drive tasks to completion even in complex, ambiguous setups.
• Willing and able to follow structured processes, and continuously improve how they are applied.
• Enthusiastic about documentation and information quality — you believe that better docs mean fewer misunderstandings and smoother integrations.
• Prior experience in partner onboarding, ad tech, SDK implementation, or data validation is a plus.
• Comfortable working in an international and distributed environment.
• Fluent English is required.
