Embedded Software QA Engineer

🌊 Who are we?

We're a smart hydration company rebuilding an industry that still runs on sugar water and single-use packaging.

Filtered water, functional flavors, zero bottles. Still, sparkling, cold, and hot. All poured from one tap. We create hydration people want to reach for, starting with the workplace where we help teams thrive.

As an AI-native company, we build at speed. In 2025, Aquablu ranked 2nd in the Deloitte Technology Fast 50 (Netherlands) and 30th in the Sifted 250 (Europe), both rankings of the fastest-growing companies by revenue growth. In 2026 we were named a winner of Maya's Culture 100 Europe Awards as one of the best workplaces to thrive in.

Growing that fast and thriving comes down to our people. Our team is our biggest asset and one that we're proud of. We're committed to maintaining our vibrant culture as we continue to grow.

The Role

You'll own software quality across AURA, our mobile app, cloud services, and internal tooling. That covers the whole chain: from a REFILL+ or Aquablu BOLD system generating telemetry, through the data pipeline and our central database, to the screen a partner or client looks at. You decide what must be tested. Our QA Automation & Pipeline Engineer builds the framework to run it, and you test directly wherever automation isn't in place yet. The engineers own the software; you own the confidence that it works.

What You'll Do

• Own test strategy, test design, and QA execution across AURA, the mobile app, cloud services, and internal tooling.

• Test frontend and UI behavior, backend and API correctness, integrations, and end-to-end flows on web and mobile.

• Set up automated regression for the weekly release, together with the QA Automation & Pipeline Engineer.

• Build contract tests that confirm REFILL+ and Aquablu BOLD telemetry lands correctly in our central database.

• Test user roles and permissions: who can see which pages and who can create, change, or delete what.

• Cover authentication, data handling, and GDPR-relevant flows.

You'll start with AURA, then extend QA to the mobile app, cloud services, and internal tooling as they scale.

What You Bring

• Full-stack QA experience across web and mobile, from UI to APIs and integrations.

• Experience owning QA for a live web platform that ships continuously.

• Hands-on data-pipeline and contract testing, following data from its source to the screen.

• Awareness of security, access-control, and GDPR testing for digital products.

• Experience working with a test-automation engineer, and the skill to test directly where automation isn't there yet.

• A pragmatic, risk-weighted approach, and the habit of using AI tools every day.

A background in connected-device or device-to-cloud products, experience setting up a QA practice, or exposure to identity and data-privacy testing sets you apart.

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.

A platform that's live, growing, and yours to make reliable. You'll shape how quality works at Aquablu, with real ownership from day one and a direct line to the engineers building AURA.
