Key Responsibilities
- Design low, medium, and high voltage electrical systems, including single-line and multi-line schematics.
- Size conductors, circuit breakers, transformers, and lightning protection systems (LPS).
- Supervise electrical installation projects on-site, ensuring compliance with local safety and technical standards like NEC, NBR 5410, or NOM.
- Perform load flow, short-circuit, and protection coordination studies and simulations for substations.
- Draft technical specifications for purchasing electrical equipment, materials, and subcontracting services.
Requirements & Skills
Day in the Life
The daily life of an Electrical Engineer is dynamic, split between the design office and on-site technical inspections. In the morning, they usually review project schedules, perform sizing calculations, run complex electrical simulations, and model systems using software like ETAP or Revit. During the afternoon, they participate in alignment meetings with clients and multidisciplinary teams (civil, mechanical, and automation) to coordinate project interfaces. They also conduct field visits to substations or construction sites to audit execution quality, inspect electrical panels, and ensure high-voltage safety protocols are strictly followed.

Frequently Asked Questions
What is the difference between a Project Electrical Engineer and a Maintenance Electrical Engineer?
A Project Engineer focuses on the design, calculation, modeling, and specification of new installations and systems. In contrast, a Maintenance Engineer ensures the operational availability of existing systems by planning corrective, preventive, and predictive maintenance schedules to prevent equipment failures.
Is an active professional registration required to sign off on electrical engineering projects?
Yes. In Brazil (via CREA) and Mexico (via Cédula Profesional), as well as in most countries, having an active professional license and registration with the local engineering council is legally mandatory to sign off on designs, installations, and take technical responsibility.
