Electrical Design Engineer

Hubbell Incorporated•Knightdale, NC

About The Position

As a Switchgear Design Engineer, you will be responsible for the design and engineering of UL 891 low-voltage switchgear systems, with a focus on busbar systems, control schemes, and integrated electrical/mechanical assemblies. This role combines electrical power system design with manufacturability and production optimization to deliver safe, compliant, and cost-effective products.

Requirements

BSEE or other related technical degree required.
Minimum 3-5 years’ work experience in a production engineering.
Designed low-voltage switchgear bus systems, including sizing, spacing, and bracing based on ampacity and short-circuit requirements.
Performed short-circuit, load flow, and voltage drop calculations to validate equipment ratings and system reliability.
Developed single-line diagrams, control schematics, and wiring diagrams for switchgear and control panels.
Engineered busbar layouts and configurations (copper/aluminum) to meet thermal, mechanical, and dielectric performance criteria.
Created and implemented control logic and interlocking schemes for breaker operation, protection, and safety.
Selected and specified circuit breakers, CTs/PTs, protective relays, and control components based on application requirements.
Configured and applied protective relay settings and developed coordination studies using tools such as ETAP or SKM.
Ensured compliance with ANSI, IEEE, IEC, UL, and NEC standards for switchgear design and safety.
Produced bill of materials (BOMs), technical specifications, and customer submittal packages.
Experience in ISO9001:2015 and ERP operating environment.
Strong interpersonal skills for developing and functioning in a team environment.
Strong written and verbal communication skills.
MS Office Software (Word, Excel, Project, etc.).

Responsibilities

Developing and validating busbar designs (ampacity, short-circuit withstand, thermal and mechanical performance).
Creating control schematics and interlocking logic.
Ensuring compliance with NEC, UL, ANSI, and IEEE standards.
Performing electrical analyses such as short-circuit and load evaluations.
Supporting equipment selection and protection schemes.
Generating detailed engineering deliverables including single-line diagrams, wiring diagrams, layouts, and bills of materials.
Analyzing and improving manufacturing processes, workflow, equipment layout, and space utilization to enhance efficiency and product quality for integrated electrical and mechanical systems.
Collaborating with fabrication teams on sheet metal design, enclosure integration, and assembly processes.
Managing multiple concurrent projects, balancing technical design, production schedules, and cost considerations.
Interfacing regularly with cross-functional teams, stakeholders, and suppliers to resolve technical issues, support production, and ensure successful project execution.
Supporting Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT), verifying functionality and resolving issues.
Collaborating with mechanical, manufacturing, and field teams to optimize design for constructability and performance.
Reviewing vendor drawings and documentation to ensure technical accuracy and compliance with project specifications.
Incorporating arc flash mitigation, grounding, and bonding practices into system designs.
Managing engineering changes, RFIs, and project deliverables to meet schedule and budget requirements.
Providing technical support during commissioning and troubleshooting of installed switchgear systems.
