Job Summary
The Senior Mechanical Design Engineer is a senior technical individual contributor who provides engineering and design leadership in the development of power distribution products for Butcher Power Products. The individual provides technical leadership, optimization, and guidance to the mechanical design team.
This role supports the design and release of high-quality, manufacturable UL 891 products by designing products, conducting technical design reviews, reviewing engineering drawings, identifying continuous improvement opportunities across design, design software, engineering tools, design for manufacturing (DFM) and assembly (DFA), and development processes.
The Senior Mechanical Design Engineer serves as a technical point of contact between Engineering, Manufacturing, and Quality, responding to design-related questions and resolving issues that arise during production.
Key Responsibilities
Technical Leadership Serve as a subject matter expert for custom UL 891 low voltage switchboard design, providing technical guidance and mentoring to other design engineers on technical best practices, standards, and process methodologies. Design Execution Complete designs for assigned projects from concept through fabrication-ready documentation, in addition to reviewing the designs of other engineers on the team. Design Reviews Lead and/or participate in design review meetings, reviewing drawings for drafting errors and verifying design intent against fabrication and assembly requirements. Codes & Standards Apply working knowledge of UL 891, UL 50, and UL 50E to switchboard and enclosure design, ensuring designs meet applicable safety, construction, and labeling requirements. Design for Manufacturability & Assembly Provide direct engineering support to production for building issues, design clarifications, and process deviations. Participate in root cause analysis and corrective actions related to manufacturing or process issues. Apply basic DFM/DFA principles, incorporating practical knowledge of shop floor processes including press brakes, laser cutting, shears, punching, and bending equipment, as well as powder coat/paint or other automated finishing processes, to ensure designs are optimized for fabrication and industrial assembly. Quality Support Support the investigation and root cause analysis process for Non-Conformance Reports (NCRs), and work within the departments Quality Management System (ISO 9001 or similar regulatory framework). Implement continuous improvement to designs, design standards, and projects to reduce waste, improve yield, ensure process compliance, and enhance overall process performance. Documentation & Standards Develop and maintain work instructions, standard operating procedures (SOPs), process control plans, and engineering documentation. Review and approve documentation for accuracy, completeness, and compliance with standards. Data & Documentation Systems Maintain accurate design data and documentation within the companys MRP system (e.g., Microsoft Dynamics D365) and applicable CAD data management tools. Cross-Functional Collaboration Serve as the production engineering point of contact for assigned projects or product lines. Coordinate with Manufacturing, Project Management, Supply Chain, Quality, and Engineering departments to align engineering support with operational needs. Technology Review current software and engineering tools to ensure accuracy, efficiency, and ease of use throughout the design process.
