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
