Principal Firmware Quality Assurance Engineer

Family Description

Applied R&D (AR) consists of target-oriented research either with the goal of solving a particular problem / answering a specific question or for multi-discipline design, development, and implementation of hardware, software, and systems including maintenance support. Supplies techno-economic consulting to clients. AR work is characterised by its detailed and complex nature in order to systematically combine existing knowledge and practices to further developing and incrementally improving products, operational processes, and customer-specific feature development.

Subfamily Description

Integration, Verification & Testing (IVT) comprises the integration of SW and / or HW or system components into system, platform, product releases, or networks and verifies the integrated entity or network against particular requirements and specifications. Covers setup and maintenance of laboratory and associated equipment, tools, and devices.
