Senior Product QA Tester (Freelance)

Your mission

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

Your profile

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
