Mission

At Vizzia, we build connected hardware deployed at scale. Our products operate in the real world, and they need to be rock solid.

Your mission is simple and critical : Make our hardware reliable before it reaches the field.

You bring structure to validation and you prevent production issues before they exist.

Fewer bugs. Fewer replacements. Fewer maintenance interventions.

You are the safeguard between design ambition and industrial reality.

Responsibilities

Write comprehensive, structured test plans : functional coverage, edge cases, stress
Execute validation campaigns across mechanical, electronic, and firmware layers
Own Pass / Fail decisions autonomously : documented, justified, and defended
Produce clear, actionable test reports highlighting risks and potential failures
Challenge hardware design choices based on validation evidence, not just validate, but analyze
Work closely with development and industrialization teams to secure production readiness
Contribute directly to achieving a defect rate ≤ 3% across the installed base
Ensure zero critical issues are discovered during production and testing phases

Engineering background in Embedded Systems, Mechatronics, or similar
Strong full-stack hardware expertise (electronics, mechanics, firmware)
Experience facing real-world hardware issues, not just designing on paper
Proven ability to write test plans: structure, coverage, acceptance criteria
Autonomous in Pass / Fail decision-making : you own your conclusions and know how to defend them
Knowledge of CE/RED and IP/IK standards
Exposure to industrialization environments
Highly rigorous : documentation and validation are second nature
Passionate about testing, validation, and building robust systems

Small team, real ownership
Direct impact on product reliability at scale
Access to hardware, tools, and autonomy to build things properly
No rigid silos , you shape how validation is done
Opportunity to grow into team leadership, certification topics, or broader hardware scope
