Junior Electrical PV & BESS System Engineer

We are seeking a motivated Junior Electrical PV & BESS System Engineer to join our Energy Efficiency team. The successful candidate will assist in the design, implementation, and maintenance of photovoltaic (PV) solar and battery energy storage systems (BESS). This role provides hands-on experience in solar and storage project development, electrical design, and system performance analysis, with mentorship from senior engineers.

Key Responsibilities:

• Assist in the design and layout of PV and BESS systems, including single-line diagrams, cable sizing, grounding, and protection schemes
• Support in preparing technical drawings, specifications, and documentation for solar + storage projects
• Conduct site assessments and feasibility studies, including load analysis, shading studies, and energy yield/storage modeling
• Perform electrical calculations (voltage drop, short-circuit, power losses, system efficiency).
• Collaborate with project managers, civil engineers, and contractors to ensure system integration between PV, BESS, and grid infrastructure
• Support the installation, testing, and commissioning of PV and BESS systems.
• Monitor system performance and assist in troubleshooting technical issues for both PV and BESS assets
• Ensure compliance with relevant electrical codes, safety standards, and grid interconnection requirements
• Stay updated on emerging solar + storage technologies, standards, and best practices

• BSc in Electrical Engineering, Renewable Energy Engineering, or related field
• Basic knowledge of photovoltaic systems, inverters, battery technologies, and electrical equipment
• Familiarity with AutoCAD, PVsyst, ETAP, HOMER, or similar software is a plus
• Understanding of IEC, NEC, IEEE, or local electrical codes and standards
• Strong analytical and problem-solving skills
• Good communication and teamwork abilities
• Willingness to learn and grow in the renewable energy and energy storage sector
• Hands-on exposure to electrical installations, testing, and commissioning

Preferred Skills (Not Mandatory):

• Internship or project experience in solar PV or BESS
• Knowledge of battery chemistries (e.g., Li-ion, flow batteries) and BMS (Battery Management Systems)
• Familiarity with SCADA and monitoring systems

In this role, you will have the opportunity to make a big impact to the overall results of the company. You will be part of a dynamic, innovative growth company which embraces new ideas and encourages everyone to contribute to our strategy.

We have an open, informal culture and we trust our people to get the job done - so we will also give you plenty of autonomy.

You will be working in an international environment which creates opportunities to share knowledge and work together with colleagues from other MET subsidiaries, mainly from the Swiss office.
