About The Role We are looking for a hands-on QA Engineer who thrives in a fast-paced product environment.

Your job is twofold: keep the platform running reliably every day, and ensure every feature we ship meets a high quality bar. Both matter equally, and you'll own both.

You'll work closely with Product, Design and Engineering on a daily basis.

Your mission Your role will be structured across 3 key areas:

Day-to-day reliability

• Monitor platform quality across web, mobile web, iOS, and Android
• Detect and escalate regressions before users do
• Own bug tracking from identification to resolution
• Be the first line of defense when something breaks in production

Release quality

• Define and execute test plans (functional, regression, exploratory)
• Lead validation phases before each release
• Make pragmatic quality trade-offs under time pressure
• Ensure consistent quality across all platforms and markets

Continuous improvement

• Improve QA processes
• Contribute to test automation on web and mobile
• Help define and track quality metrics (defect rate, coverage, release quality)
• Be a user-first advocate in every product discussion
• Make quality visible and measurable for Product and leadership
• 3-4 years of QA experience in a product company on B2C
• Comfortable managing both ongoing platform quality and new feature validation simultaneously
• At ease with high release frequency and shifting priorities
• Strong ownership mindset — you notice problems and act on them
• Experience testing web and mobile applications
• Familiarity with bug tracking tools (Jira or equivalent)
• Bonus: experience with test automation (Playwright, Cypress, Appium or similar)

Bonus Points For:

• Experience with AI/ML for testing processes and test automation (Selenium, Cypress, Appium…) is a plus
• Experience in high-traffic consumer products (marketplace, travel, e-commerce) in fast-growing or scale-up environments is a plus

Why join Cozycozy?

🚀 You’ll operate in a key role in the development of a fast-growing travel-tech startup.

🌍 You will work closely with founders and fellow engineers in impact-led small teams.
