What you bring to the role:

• Degree: Bachelor’s or Master’s degree in Electrical Engineering, Power Engineering, Civil Engineering, or Construction Management.
• Experience: Minimum 5–7 years of experience as a Site Manager or Construction Manager in large-scale energy infrastructure projects (e.g., high-voltage substations, wind/solar farms, or large industrial plants).
• Grid Connection Experience: Proven track record working with high-voltage systems (110kV or higher) and familiarity with Bulgarian grid connection procedures (ESO/ЕРП regulations).
• Language Skills: Professional working proficiency in both Bulgarian and English (written and spoken).
• Technical Skills & Regulatory Knowledge: Deep practical knowledge of the Bulgarian regulatory framework governing the commissioning of energy infrastructure (ZUT procedures for Category 1/2 structures). Proven experience in successfully leading projects through State Acceptance Committees (ДПК) to secure Act 16.Familiarity with ESO's technical requirements and protocols for the energization and testing of high-voltage equipment.
