- Perform and/or review electrical engineering calculations and studies, including:
- Earthing / grounding studies
- LV, MV and HV cable sizing and thermal calculations
- Load-flow studies
- Power system analysis
- Prepare technical specifications, equipment datasheets, design calculations, design reports and engineering documentation.
- Support the technical specification and selection of major substation equipment, including:
- Power transformers
- HV/MV switchgear and GIS
- Circuit breakers and disconnectors
- Current and voltage transformers
- Surge arresters
- Busbars and conductors
- HV/MV cables and cable systems
- Earthing systems
- Ensure designs comply with applicable IEC, EN, DIN and VDE standards, project specifications and relevant German grid operator requirements.

- Coordinate technical interfaces with civil, structural, protection & control, SCADA/telecommunication, mechanical and construction disciplines.
- Review supplier drawings, technical documentation, calculations and equipment submittals.
- Support procurement activities through technical bid evaluations, supplier clarification meetings and equipment selection.
- Provide engineering support during construction, installation, testing and commissioning.
- Perform site visits and technical inspections to verify compliance with approved designs and project requirements.
- Participate in and oversee Factory Acceptance Tests (FATs) for major electrical equipment.
- Support project permitting, technical documentation and coordination with relevant authorities and grid operators where required.
- Participate in interdisciplinary design reviews and identify opportunities for technical optimisation, constructability improvement and cost-efficient engineering solutions.
Your Profile
- University degree (Dipl.-Ing., BSc, MSc or equivalent) in Electrical Engineering, Power Engineering or a related discipline.
- Professional experience in the design or engineering of HV/MV substations, transmission/distribution systems or power infrastructure projects.
- Good understanding of primary substation engineering and HV/MV equipment.
- Knowledge of engineering calculations including earthing, lightning protection, cable sizing, short-circuit calculations and load flow.
- Familiarity with relevant IEC/EN standards; knowledge of DIN/VDE standards and German TSO/DSO requirements is a strong advantage.
- Experience with AIS and/or GIS substations is desirable.
- Strong proficiency in AutoCAD for electrical layouts and engineering drawings.
- Experience with power system analysis and engineering software such as DIgSILENT PowerFactory, ETAP or equivalent tools is an advantage.
- Experience with protection & control systems, secondary engineering or substation automation is considered an advantage.
- Experience with auxiliary building services and MEP systems such as HVAC, lighting and LV distribution is considered an advantage.
- Proficiency in Microsoft Office and standard engineering documentation tools.
- Professional proficiency in English is required.
- German language skills are highly desirable and will be considered a significant advantage for coordination with German clients, grid operators, authorities and suppliers.
- Strong analytical and problem-solving skills with a structured engineering approach.
- Ability to work independently while collaborating effectively within international and multidisciplinary project teams.
- Strong communication, coordination and technical documentation skills.
- Willingness to travel within Germany and internationally for project meetings, site activities and FATs when required.
What We Offer
- A Berlin-based hybrid position combining office collaboration with flexible remote working.
- The opportunity to work on major HV/MV substation and grid infrastructure projects in Germany and across Europe.
- Direct involvement in projects supporting grid expansion, renewable energy integration and the German energy transition (Energiewende).
- Exposure to the complete project lifecycle – from concept and detailed engineering through procurement, construction and commissioning.
- The opportunity to work with leading European TSOs, DSOs, utilities, developers and equipment manufacturers.
- Collaboration with an experienced international engineering and construction team.
- A role with significant technical responsibility and opportunities to develop expertise in HV/MV substation engineering and power systems.
