Assembly Technician-Wiring & After-Sales Service

Reporting to the Operations Manager, you share your activity between the assembly of electrical cabinets in the workshop and after-sales service in the field, following a weekly alternating rhythm: one week dedicated to assembly, one week dedicated to after-sales service.

Every other week, you wire and assemble in the workshop the electrical cabinets and storage systems that equip our installations. The following week, you intervene to test, diagnose, and repair installations and machines, in the workshop or directly at our clients' premises.

This way of working allows you to keep one foot in production while remaining regularly in contact with the field and clients - a balance that requires rigor on both sides, but which avoids the routine of a single-task position.

Your missions:

Assembly, wiring and production (Assembly weeks):

• Read and interpret electrical diagrams and wiring plans.
• Wire and assemble low-voltage electrical cabinets (protections, inverters, regulators, storage systems).
• Respect current standards (NIBT/OIBT) and internal quality standards.
• Check your own work and report non-conformities before shipment or installation.
• Coordinate with the design office and logistics for technical points and material availability.

After-sales service and field interventions (After-sales weeks):

• Diagnose faults on photovoltaic installations, storage systems, and associated electrical installations.
• Repair and put back into service, in the workshop or directly at the client.
• Intervene autonomously at the client: preparation, execution, final check, informing the client of the subsequent steps.
• Write intervention reports and keep after-sales service tickets up to date.
• Report recurring faults or design defects identified in the field to the design office.

Profile sought

You hold a CFC as an electrical assembler, electrical installer, automation technician, or an equivalent training, and you have a first concrete experience in wiring electrical cabinets. Experience in troubleshooting or field after-sales service is an asset.

You read an electrical diagram with ease, you work with rigor, and you know how to diagnose a fault methodically rather than by trial and error. Comfortable both in the workshop and facing a client, you are autonomous in your on-site interventions and you know how to represent the company with professionalism.

You hold a category B driver's license. Knowledge of photovoltaics, battery storage, or off-grid installations is an appreciated plus. Versatility and a taste for varied work, characteristic of a SME environment, suit you.
