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:
o Edge cases
o Logical inconsistencies
o UX issues
o 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:
o Ambiguity
o Incomplete specs
o 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
