• 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

Competencies

• Strong Technical Capability
• Solid grasp of three-phase electric power concepts, power distribution systems, power control and protection strategies are preferred.
