Cable Assembler Technician & After-Sales Service

Based in Morat, in the canton of Fribourg, Swiss-Green Engineering Sàrl is a Swiss company specialised since 2009 in renewable energies, with particular expertise in photovoltaics and energy storage solutions.

Our activity covers the entire energy chain: solar production, battery storage, off-grid autonomous systems, grid-connected installations and embedded energy solutions. We design and market solutions intended for both individuals and professionals, with one goal: to promote more autonomous, sustainable and intelligent energy.

Swiss-Green Engineering also stands out for its strong technical expertise. The company notably designs its own SMARTES storage systems in Switzerland and supports its clients and partners in the study, sizing, commissioning and technical support of their installations.

With a human scale, our team operates in a sector undergoing major transformation, at the crossroads of engineering, technological innovation and the energy transition.

Reporting to the Operations Manager, you split your activity between assembling 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 cable and assemble electrical cabinets and storage systems that equip our installations in the workshop. The following week, you intervene to test, diagnose and repair installations and machines, either in the workshop or directly at our clients’ premises.

This arrangement allows you to keep a foot in production while regularly staying in contact with the field and clients — a balance that requires rigour on both sides but avoids the routine of a single-task position.

Your tasks:

Assembly, cabling and production (Assembly weeks):

• Read and interpret electrical diagrams and wiring plans.
• Cable and assemble low-voltage electrical cabinets (protections, inverters, regulators, storage systems).
• Comply with 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 recommission, either in the workshop or directly at the client’s site.
• Work autonomously at the client’s site: preparation, execution, final check, informing the client of follow-up actions.
• Write intervention reports and keep after-sales tickets up to date.
• Report recurring faults or design defects identified in the field to the design office.
