Quality Assurance & Validation Tester

About the role
We are looking for a quality assurance & validation tester to join our virtualization test team. In this role, you act as an internal customer and evaluate how the system behaves in real use cases across embedded, cloud‑based and virtualized environments. Your focus is on performance, robustness and user‑centred behaviour — understanding what works, what doesn’t, and why.
You will validate practical workflows such as logging into portals, accessing cloud features and running embedded functionality. By challenging the system through exploratory and non‑functional testing, you uncover unexpected behaviour and provide clear go/no‑go decisions for each delivery.
What you will do
You will work hands‑on with behaviour‑driven testing, validating user stories, capabilities and complete user flows. You explore how the system responds under different conditions, verify stability when new features are introduced and identify issues that appear outside predictable scenarios.
In addition, you will:

You assess each delivery and give a clear go/no‑go decision grounded in actual test results


Validate reproducibility in virtualized environments


Compare performance between virtualization and target hardware


Run integration scenarios with multiple virtual components


Apply fault‑injection techniques to expose weaknesses


Check timing, synchronization and behaviour under varying load


Assess scalability in larger virtual setups


Investigate undocumented or unexpected system responses

Who you are
You have a background in software testing and a natural curiosity for how systems behave in practice. You look beyond written requirements and focus on what users actually need. You enjoy isolating problems, identifying root causes and helping the team deliver stable, reliable functionality.
Required skills & experience
Solid background in software testing


Ability to design and execute test cases


Familiarity with exploratory testing methods


Understanding of performance‑focused and other non‑functional testing


Capability to test embedded or hardware‑related functionality


Ability to validate user journeys and act as an internal customer


Confidence in providing clear go/no‑go decisions

It's a plus if you have
Knowledge of QEMU or similar virtualized environments


Exposure to hardware‑in‑the‑loop test setups


Familiarity with safety‑related test documentation


Experience validating cloud‑based functionality

Why join?
In this role, you work close to the product and play a key part in ensuring that every delivery is reliable and user‑ready. You help developers understand real system behaviour, uncover weak spots and contribute to a more stable and predictable platform. You’ll join a modern engineering environment where clarity, curiosity and hands‑on problem‑solving are central.
