Industrial Electric Mfg. (IEM) is the largest independent full-line manufacturer of custom power distribution systems in North America. Founded more than 75 years ago in Fremont, California, IEM grew alongside Silicon Valley and today operates over 1.7 million square feet of manufacturing capacity. With $1B+ in annual sales and 10,000+ commissioned projects across technology, data centers, commercial, energy, utilities, healthcare, industrial, and infrastructure markets, IEM continues to deliver exceptional product quality, dependable service, and the flexibility to meet complex technical requirements at scale.

The R&D Mechanical Engineer is responsible for collaborating or leading the design, testing and certification of innovative electrical power products in collaboration with a diverse team of electrical, mechanical and manufacturing engineers. This role requires a strong intuition of fundamental engineering concepts across multiple disciplines and an ability to effectively manage the product development process under limited direction.

• Ensure the execution and implementation of the New Product Introduction (NPI) engineering work for assigned projects.
• Collaborate with Senior and Lead Engineers in writing detailed engineering specifications and developing concept drawings in collaboration with Sales and other stakeholders.
• Coordinate with Nationally Recognized Testing Laboratories (NRTLs) to define product evaluation and certification scope.
• Lead the creation of detailed design drawings, 3D models and bills of material for prototype equipment and test articles.
• Develop and document test plans according to the relevant standards. Common tests include full-load temperature rise, dielectric and BIL, short-circuit and withstand current, mechanical endurance, component failure, environmental, functional and seismic shake-table tests.
• Support the testing process at in-house and third-party laboratories. Travel up to 20% to support testing and other product development tasks in-person. Evaluate test results and revise designs based on empirical data and established engineering concepts.
• Characterize the electrical, thermal and mechanical performance of common design elements through testing, simulation and/or analytical methods. Develop standard design criteria and models.
• Work closely with manufacturing engineering to implement Design for Manufacturability (DFM) concepts throughout the new product development process.
• Working with Mechanical Designers.
• Conduct failure analyses of existing products and identify opportunities for continuous improvement.

• Minimum 3 years of experience designing low and/or medium voltage power distribution equipment or related products.
• BSME or equivalent in experience.
• Experience with NRTL (UL, CSA, etc.) evaluation, testing and certification processes.
• Experience with common standards for electrical equipment (UL 891, 1558, 508A; IEEE C37.20, etc.).
• Design Experience using Solid Works to produce 3D models is highly preferred.
