Senior Electrical Design Engineer SME

Cynet Systems•York, SC

About The Position

An experienced design engineer providing technical leadership in the design, analysis, modification, testing, and implementation of electrical power systems and equipment. The role leads complex engineering projects involving transformers, switchgear, circuit breakers, protective relays, motor control centers, generators, and electrical distribution systems. It serves as a technical authority, ensuring compliance with applicable codes, standards, licensing requirements, and engineering processes while supporting safe, reliable, and efficient system performance. The engineer develops design inputs, modification packages, calculations, specifications, testing requirements, and design basis documents. Workers at this level solve complex problems in their engineering specialization with limited supervision, apply fundamental concepts and procedures to progressively complex and varied work, and are expected to develop advanced skills and work with increasing independence. The role requires a minimum of 15 years of discipline experience and unique SME skills.

Requirements

Minimum 15 years of discipline experience and unique SME skills.
Ability to work on assigned projects with minimal supervision.
Ability to work as part of a team, be self-motivated, exercise flexibility, and take personal responsibility for assigned accountabilities.
Technical abilities in power system analysis and modeling, protective relay coordination, transformer sizing and application, switchgear and circuit breaker specification, cable ampacity and routing calculations, grounding system design, electrical equipment troubleshooting, technical report and specification development, risk assessment, and engineering change implementation.
Strong verbal and written communication skills and stakeholder engagement.
Technical rigor, attention to detail, problem solving, troubleshooting, design ownership, accountability, cross-functional collaboration, project planning and execution, and a focus on safety and compliance.
Hard hat and safety gloves are required.
