🌊 Who are we?

At Aquablu, we’re not just bottling innovation, we’re engineering a cleaner, smarter future of hydration. Since 2018 our founders, Marnix and Marc, have been on a mission to eliminate single-use plastics by replacing them with game-changing, connected water systems. Now poured in 16 countries and counting, partners like Heineken, Adyen, and Marriott are already on board. Join us in our mission to hydrate a billion people to thrive everyday!

“We don’t just build devices; we build momentum for a planet that deserves better.” – Marnix, Co-founder of Aquablu

At Aquablu, our technology fuels sustainability. From smart water systems to connected devices, everything we build needs to perform at the highest level. That’s where you come in: ensuring that our embedded software is rock-solid, reliable, and ready for real-world impact. You will be the guardian of quality, driving testing strategies, solving complex hardware/software challenges, and making sure every product that leaves our hands meets the Aquablu standard: exceptional

What You’ll Do

• Own testing & validation through designing and executing detailed test plans to ensure our firmware functions exactly as intended; no bugs, no surprises.
• Work hands-on with our hardware, combining deep technical understanding with creative testing approaches to run both manual and automated tests.
• Take full ownership of field issues by replicating, documenting, and collaborating with developers to find and fix the root cause quickly.
• Go beyond the symptoms to uncover what really went wrong, validate the fixes, and prevent future issues.
• Continuously improve QA methods, documentation, and workflows to make testing smarter, faster, and more efficient.
• Maintain clear, structured, and traceable documentation for all test plans, environments, and results.
