Job description

Job Summary:

The Sr. Electrical Engineer (R&D) is responsible for collaborating on or leading the electrical

design, testing, and certification of new low and medium voltage power distribution products.

This role works closely with cross-functional teams to ensure product safety, reliability,

manufacturability, and compliance with the relevant industry standards, and it builds the design

criteria, calculators, and reusable models that make each product line repeatable rather than one

off. The ideal candidate brings strong engineering fundamentals, technical leadership, and the

ability to carry complex projects from concept through production under limited direction.

Key Responsibilities:

Lead the electrical design for power and control on new product development

projects, from project initiation through production implementation.

Execute and implement the New Product Introduction (NPI) electrical engineering

work for assigned projects.

Write detailed electrical engineering specifications and lead the creation of electrical

schematics, wiring drawings, and bills of material for prototype equipment and test

units, in collaboration with commercial, mechanical, and CAD stakeholders.

Work with Nationally Recognized Testing Laboratories (NRTLs) to define product

evaluation and certification scope and the qualification path for each product

configuration.

Develop and document test plans according to the relevant standards. Common tests

include full-load temperature rise, dielectric and BIL, and short-circuit and withstand

current tests.

Support the testing process at in-house and third-party laboratories. Evaluate test

results and revise designs based on empirical data and established engineering

concepts.

Characterize the electrical and thermal performance of common design elements

through testing, simulation, and analytical methods. Develop standard design criteria,

design calculators, and reusable design models.

Develop modular, configurable designs and option matrices that support standardized

quoting and CPQ.

Work closely with manufacturing engineering to implement Design for

Manufacturability (DFM) concepts throughout the new product development process.

Work with mechanical and electrical designers to integrate electrical design into

equipment layouts and general arrangement drawings.

Conduct failure analysis of existing products and identify opportunities for continuous

improvement.

Engineer and design switchboard and switchgear to customer specifications, including

selection of electrical components (e.g., circuit breakers, relays, transformers) against

performance criteria, applicable standards, and project requirements.

Serve as the primary technical point of contact for the equipment design through

manufacturing and testing, including Factory Witness Test (FWT) troubleshooting, and

as a technical resource to Sales and Project Management on proposals and customer

meetings.

Mentor and support the professional development of junior engineers through design

reviews and knowledge sharing.

Serve as a senior technical resource on production design work as assigned.

Assignments may span new product development and production engineering as

business needs require.

Must comply with the company’s safety policies.

Qualifications:

BSEE or equivalent in experience. Master’s degree preferred.

Minimum 5 years of experience in the electrical design of low and/or medium voltage

power distribution equipment or related products.

Experience with NRTL (UL, Intertek/ETL, CSA, etc.) evaluation, testing, and

certification processes.

Experience with common standards for electrical equipment (UL 891, 1558, 508A).

Familiarity with IEEE/ANSI C37.20.2, C37.04, C37.06, C37.09; CSA C22.2; EEMAC G8-3.2

design guidelines; and NFPA 70E.

Design experience using AutoCAD or similar to produce electrical diagrams and

schematics.

Ability to travel up to 20% to support testing and other product development tasks in

person.

Previous field service experience, knowledge and understanding is a plus.

Core Competencies:

Expert knowledge of applicable electrical standards (UL, NEC, ANSI, IEEE) and

comprehensive knowledge of switchgear, switchboards, controls, and complex power

distribution systems.

Solid grasp of three-phase electric power concepts and power control and protection

schemes.

Design standardization, including design criteria, calculators, and reusable design

models.

Excellent communication and technical writing skills, with strong organizational skills

and precise attention to detail.

Technical mentorship and cross-functional collaboration.
