Post description
This position lies at the heart of the reliability and transfer of a breakthrough industrial technology dedicated to the installation of laser-based communication systems.
As a Technical Writer, your role goes far beyond writing.
You are the person who makes tangible and understandable what technical teams design and deploy in the field.
Each document you produce guides the installation, maintenance, training, and operation of complex systems, becoming an essential tool to ensure that the technology functions properly, is used correctly, and can be deployed worldwide.
You transform technical information that may be fragmented or highly specialized into clear, precise, and structured content, enabling all stakeholders (engineers, technicians, trainers, and customers) to understand and act efficiently.
Your work ensures that cutting-edge systems do not remain abstract ideas, but become operational and accessible, with rigor, precision, and impact.
