Senior Product QA Tester (Freelance)

Original Advert

About Holidog:


Holidog connects millions of pet owners with trusted sitters for boarding, walks, and home visits across Europe.


Our ambition is bold: double the company and become the #2 global platform in pet care.

To get there, we're simplifying pet care at scale and building a product designed to grow internationally from day one.


About the role:

  • We're looking for a senior, product-minded QA tester to take full ownership of testing across each release cycle of our web application.
  • This is not a classic QA role.
  • You will be responsible for validating features end-to-end, anticipating edge cases, identifying inconsistencies and technical issues, and challenging product and UX decisions when needed.
  • Your feedback must be clear, structured, prioritized, and directly actionable for developers.
  • You will work directly with the CTO / main developer, in a fast-paced, highly iterative environment.


About the product & the way we work:

  • C2C marketplace (web app, mobile app coming next)
  • Product fully developed with AI assistance
  • No fully locked specs
  • No final design upfront
  • Features are defined at a high level, then built and refined through short iterations
  • Multiple QA rounds until production-ready

We use internal AI-based tools to speed up testing:

  • Integrated QA tool directly on the platform
  • Automatic generation of test users and scenarios


The value we expect from you is not running test scripts, but:

  • Understanding the product deeply
  • Identifying product, UX, and business risks
  • Structuring QA feedback in a way that helps fast decision-making


Your responsibilities:

  • Own QA for each release from start to production
  • Master end-to-end user flows
  • Identify:
  • Edge cases
  • Logical inconsistencies
  • UX issues
  • Technical or data-related risks
  • Challenge product and UX choices when necessary
  • Structure and prioritize QA feedback for developers
  • Collaborate closely with the CTO during iterations
  • Help define a solid QA approach even with incomplete specs



Mandatory requirements (must meet all three before applying):

  • AI-Native QA - Daily use of AI tools (Claude Code, Codex, etc.) to explore codebases, generate or improve tests, debug issues, and identify root causes
  • Advanced Browser Automation via MCP - Expertise in Playwright or Puppeteer MCP, Chrome DevTools MCP / browser protocols; able to simulate complex user behavior and debug browser-level issues
  • Autonomous Codebase Exploration - Able to independently explore large React / Next.js applications, understand system structure, identify coverage gaps, and propose improvements proactively


What we're looking for:

  • Senior QA profile (strong autonomy required)
  • Strong product mindset (not just bug hunting)
  • Comfortable working with:
  • Ambiguity
  • Incomplete specs
  • Fast iterations
  • Able to think in terms of risk, impact, and priorities
  • Clear, direct communicator (written and verbal)
  • Experience with marketplaces or complex user flows is a big plus
  • English fluency required


Important: please read before applying

This role is not suitable if:

  • You need detailed specs or final designs before testing
  • You mainly focus on automation frameworks and scripts
  • You expect a rigid, process-heavy QA environment
