A Snapshot of Your Day

As the Head of Testing Field & High Voltage Laboratory, you will lead all testing activities associated with the manufacturing, final acceptance, and technical release of Large Power Transformers up to 400 kV and 1550 kV BIL. You will guide the operation of a modern high-voltage laboratory and test field, ensuring that routine, type, special, and customer-specific tests are planned, executed, documented, and released safely, efficiently, and in full compliance with contractual requirements, iternational standards, and internal quality expectations.

This is a hands-on technical leadership role. You will serve as a key technical reference for transformer electrical testing, high-voltage laboratory operation, customer Factory Acceptance Tests (FAT), failure investigation, and technical problem solving. Your engineering judgment will be essential to interpret sophisticated test results, validate transformer readiness for shipment, and support continuous improvement across testing, manufacturing, quality, EHS, and customer-facing processes.

How You'll Make an Impact

- Lead the test field and high-voltage laboratory organization, aligning testing priorities with factory objectives, EHS requirements, production schedules, and customer commitments.
- Ensure the safe, accurate, and compliant execution of routine, type, special, and customer-specific tests for Large Power Transformers up to 400 kV and 1550 kV BIL.
- Provide expert interpretation and technical release of transformer test results, including Partial Discharge measurements, Lightning / Switching Impulse tests, dielectric tests, losses, impedance, ratio, polarity, resistance, and temperature rise results.




- Act as a technical reference during customer meetings and FAT execution, explaining testing methodologies, results, deviations, equivalencies, and standard/customer requirement differences with clarity and credibility.
- Lead or actively support failure investigations, task forces, and Root Cause Analysis activities related to test discrepancies, non-conformities, customer concerns, and field incidents until technical closure.
- Develop team capabilities, strengthen audit readiness and documentation quality, and drive continuous improvement initiatives related to quality, safety, productivity, digitalization, data integrity, and customer satisfaction.

What You Bring Education

- Bachelor's Degree in Electrical Engineering required.
- Solid technical foundation in power systems, high-voltage engineering, electrical machines, or transformer technology.
- Master's Degree preferred in a technical engineering discipline related to Power Systems, High Voltage Engineering, Transformer Design, Electrical Insulation, or Asset Management.
- Additional training or specialization in transformer testing, dielectric diagnostics, partial discharge measurement, or high-voltage laboratory operation is preferred.

Professional Experience

- Minimum of 10 years of technical experience in power transformer testing,



preferably in a manufacturing test field or high-voltage laboratory environment.
- Primarily technical experience, not only administrative, with demonstrated capability to interpret test results and make engineering judgments based on technical evidence.
- Proven experience with routine, type, special, and customer-specific tests for Large Power Transformers.
- Experience interacting directly with customers, consultants, and third-party inspectors during Factory Acceptance Tests.
- Experience supporting or leading technical investigations, task forces, and Root Cause Analysis activities related to test discrepancies, non-conformities, customer concerns, or field incidents.
- Desirable experience in transformer construction, manufacturing processes, and design principles to support practical and technically sound problem analysis.

Technical Knowledge and Core Competencies Transformer Testing and Result Interpretation
