About the role
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, IE
