EMBEDDED / CRYPTOGRAPHY SPECIALIST

Your next mission: System Validation Engineer
Join our project team dedicated to secure identity and document solutions. We are looking for a hands-on System Engineer with strong Linux and deployment knowledge and practical experience validating complex system environments.
The primary focus of this role is hands-on validation and integration testing of complete system landscapes — including infrastructure, deployments, APIs, integrations, and environment configurations.
This is not a classical QA role. We are looking for an engineer who understands how systems are deployed, configured, integrated, and validated end-to-end.
