We are working with a well-established engineering organisation seeking an experienced Senior Protection & Secondary Design Engineer specialising in Medium Voltage (MV) systems.

In this role, you will take ownership of protection system design and secondary engineering, supporting projects end-to-end — from initial concept through to commissioning.

This is a highly technical position suited to someone with strong expertise in power system protection, relay configuration, and schematic design.

Key Responsibilities

• Design complete protection schemes for MV systems, including feeders, transformers, generators, and switchgear

• Develop detailed secondary schematics in line with project specifications and industry standards

• Select appropriate protection relays based on system studies and project requirements

• Configure, parameterise, and commission protection relays

• Carry out relay testing including functional testing, secondary injection, and commissioning tests

• Specify and select Current Transformers (CTs) and Voltage Transformers (VTs) for protection and metering

• Ensure compliance with international standards (IEC, IEEE) and client specifications

• Prepare and review technical documentation, protection philosophies, and drawings

• Support troubleshooting, fault analysis, and system optimisation

• Provide on-site support during commissioning and project delivery when required

• Collaborate closely with multidisciplinary teams including project managers, primary engineers, and commissioning teams

Your Profile

• Extensive experience in power system protection engineering, particularly within Medium Voltage environments

• Strong background in secondary design and protection scheme development

• In-depth knowledge of protection relays and leading manufacturers

• Hands-on experience with relay testing and commissioning

• Solid understanding of CT and VT selection and sizing

• Proficiency in schematic design tools such as:

• EPLAN

• AutoCAD

• Experience with Elecdes is a strong advantage

• Ability to work independently and take ownership of technical decisions

• Strong analytical and problem-solving skills

• Willingness to travel to project sites as required

• Fluent in English and German (written and spoken)

Experience Required

• 7–10+ years of experience in protection engineering and secondary system design (MV level)

What’s on Offer

• Opportunity to work on complex and high-impact energy projects

• End-to-end involvement across design, testing, and commissioning

• Flexible working environment with project-based travel

• Long-term stability within a growing engineering organisation
