• Execute and support the configuration and customization of mechanical designs to meet project- and customer-specific requirements.

• Provide maintenance of line (MOL) support for operational teams across the business

• Perform advanced 3D modeling and create detailed 2D drawings, including customer coordination drawings, fabrication drawings, and assembly documentation.

• Maintain and update bills of materials (BOMs), ensuring alignment with released designs and manufacturing standards.

• Collaborate with cross-functional teams, including project managers, R&D engineering, manufacturing, manufacturing engineers and quality, to ensure designs meet functional, schedule, and cost targets.

• Optimizing and configuring the custom designs of mechanical solutions to meet client-specific requirements, focusing on manufacturability and compliance with industry and internal standards.

• Reviewing designs to maintain accuracy, quality, and compliance with industry guidelines, and UL 891/1558.

• Incorporate manufacturing, testing, field, and installation feedback into design updates and product refinements.

• Contribute to peer reviews of designs to ensure high-quality deliverables and compliance with engineering standards.

• Assisting in identifying and addressing project challenges, ensuring alignment with timelines and client expectations.

Essential Functions

• Apply established system-level configuration strategies and modules that balance technical requirements, manufacturability, and cost-effectiveness.

• Translate product requirements into engineering system specifications and technical documentation

• Support prototyping, testing, validation, and product launches of system configurations

• Prepare high-quality documentation, including fabrication-level drawings and assembly instructions.

• Design and refine mechanical components and assemblies

• Identify and address discrepancies in BOMs promptly to minimize delays and errors during production.

• Analyze field and quality data to drive product improvements

• Contribute to workflow templating and automation initiatives to increase project throughput and reduce errors.

• Provide informal guidance and technical support to junior engineers and designers

• Share best practices related to 3D modeling, drafting standards, fabrication methods and documentation quality.

• Participate in peer reviews to improve overall team output and consistency.

• Work closely with the senior engineers, lead engineers, manufacturing engineers, quality engineers and fabrication teams to refine designs for manufacturability.

• Coordinate with internal stakeholders across engineering and manufacturing locations to support project execution.

• Communicate design intent, assumptions, and changes clearly to relevant teams.

Qualifications

• Experience working in a configure-to-order (CTO) or engineered-product environment preferred.

• Experience in manufacturing and other related cross functional engagement is an asset.

• Exposure to design-to-order or custom engineering environment is an asset.

• Ability to manage multiple projects and prioritize tasks effectively in a fast-paced environment

• Familiarity with low or medium voltage switchgear, utility systems, or the power industry is preferred.

• Proficiency in sheet metal design, including manufacturability and cost optimization.

• Strong attention to detail, analytical thinking, and problem-solving skills.

• Proficiency with SolidWorks, AutoCAD, or Pro E; Finite Element Analysis (FEA) experience is a plus.

• Knowledge of UL891/1558 design guidelines and NFPA70E are desirable.

• Strong communication skills, both written and verbal, with the ability to collaborate across teams.

Education & Experience

• BSME or equivalent required, MSME is preferred

• 7+ years of experience in mechanical design, preferably in CTO or system engineering.

Compensation

The salary range for this role is $91,200-$124,800 per year, based on location, experience, and qualifications.
