• Collaborating with clients, project managers, and internal teams to ensure designs are aligned with project goals and timelines.
• Reviewing designs to maintain accuracy, quality, and compliance with industry guidelines, such as IEEE/ANSI C37.20 and UL 891/1558.
• Providing technical support during manufacturing and installation phases to ensure seamless execution.
• Conducting 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.

Design To Order Project Workflow

• Develop project‑specific designs that balance technical requirements, manufacturability, and cost‑effectiveness.
• Prepare high‑quality documentation, including fabrication‑level drawings and assembly instructions.
• Identify and address discrepancies in BOMs promptly to minimize delays and errors during production.
• Drive workflow templating and automation initiatives to increase project throughput and reduce errors.

Mentorship And Team Development

• Assist in training junior team members in best practices for 3D SolidWorks modeling, 2D AutoCAD drafting, and compliance with design standards.
• Provide constructive feedback during peer reviews to improve the team's technical output.

Collaboration And Support

• Partner with the Lead Engineer, manufacturing engineers, and fabrication teams to refine designs for manufacturability.
• Act as a point of contact for technical inquiries during fabrication and installation.
• Facilitate communication and collaboration across multiple engineering and manufacturing sites to align expectations and processes.

• 5‑7+ years of experience in mechanical design, preferably in DTO or custom engineering.
• Professional Engineer (PE) license is preferred.
• Experience mentoring and guiding junior engineers preferred.
• Experience working in a design‑to‑order or custom engineering environment is strongly preferred.
• Ability to manage multiple projects and prioritize tasks effectively in a fast‑paced environment.
• Familiarity with 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 IEEE/ANSI C37.20, UL891/1558 design guidelines and NFPA70E are desirable.
• Strong communication skills, both written and verbal, with the ability to collaborate across teams.
