SENIOR MANUFACTURING PROCESS ENGINEER

Who We Are

Westrafo is a leading company in the electromechanical and electrical transformer industry, founded in 2014, with a presence in Italy, Ghana, and North America.

Our product portfolio includes a wide range of integrated solutions for the energy sector, including power transformers and distribution transformers , which can be customized for a variety of applications, such as:

• Solar photovoltaic
• Wind energy
• Hydrogen
• Energy storage
• Various industrial applications

We are seeking an experienced Manufacturing Process Engineer to own, maintain, and continuously improve the established manufacturing process system for oil-immersed distribution transformers up to 10 MVA, 72.5 kV. The role ensures that work instructions, process parameters, and quality controls remain current based on production performance, quality/test feedback, engineering changes, materials, and installed equipment, while providing expert technical support to Production, Quality, Engineering, and Maintenance.

Mandatory Gate Criterion : Direct hands-on experience working for a transformer manufacturer is mandatory. Candidates without proven transformer manufacturing experience will not be considered; generic mechanical, electrical equipment, or process engineering experience alone is insufficient.

WHAT WILL YOU DO?

·Process ownership and change control: Maintain and update Process Flows, Manufacturing Routings, Work Instructions/process sheets, Machine Setup Sheets, critical parameters, control points, acceptance criteria, and Control Plans. Implement controlled revisions based on production feedback, quality/test results, engineering, material or equipment changes, and lessons learned.

·Technical support and problem solving: Provide hands-on support to Production, Quality, Engineering, and Maintenance; troubleshoot manufacturing issues, perform root-cause analysis, distinguish design, material, equipment, and process causes, and define corrective/preventive actions.

·Winding, insulation, and drying expertise: Provide expert support for LV foil and HV/MV layer winding, machine/mandrel setup, conductor and insulation tension, winding speed and alignment, insulation handling, moisture control, and drying/vacuum cycles; adjust process parameters when production evidence requires improvement.

·Active part, tanking, and oil processing expertise: Support active part assembly, clamping, electrical connections and clearances, tanking, vacuum/leak control, oil filtration/dehydration/degassing, vacuum oil filling, impregnation, sealing, and final assembly requirements including torque, gaskets, and inspection criteria.

·Tooling, jigs, and fixtures: Define, design, or coordinate production tooling, mandrels, jigs, fixtures, gauges, and positioning/lifting aids required to ensure repeatability, product quality, ergonomics, and safe execution of manufacturing operations.

·Continuous improvement and training: Use defects, rework, NCRs, test findings, and operator feedback to improve First Time Right, repeatability, equipment utilization, and lead time; update training materials and operator qualifications after process changes.

WHAT ARE WE LOOKING FOR?

·Education: Bachelor's or master's degree in Electrical, Mechanical, Manufacturing, Industrial Engineering, or a comparable technical discipline.

·Experience: Direct hands-on experience in a transformer manufacturing company is mandatory. 5+ years in transformer manufacturing/process engineering is preferred; distribution transformer experience is strongly preferred.

·Technical expertise: Deep practical knowledge of LV foil and HV/MV layer winding, transformer insulation and drying, active part assembly, vacuum systems, oil treatment/vacuum filling, final assembly, and the related production equipment.

·Process, quality, and tooling capability: Proven ability to maintain and improve established processes, manage controlled changes, define critical-to-quality parameters, analyze manufacturing/quality problems, implement effective process corrections, and develop or specify practical jigs and fixtures.

·Professional skills and English: Strong shop-floor engineering mindset, independent problem solving, and effective collaboration with Production, Engineering, Quality, and Maintenance. Working English is mandatory for technical documentation, reports, discussions, and supplier communication.

· Knowledge of Italian is mandatory, wi
