• Maintain CAD assemblies, part configurations, and engineering documentation within the company's CAD and Product Lifecycle Management (PLM) systems.
• Perform minor mechanical CAD modeling and drawing revisions under the direction of design engineers, including dimension updates, tolerance changes, and documentation corrections.
• Coordinate the Engineering Change Request (ECR) and Engineering Change Order (ECO) process, ensuring design changes are accurately documented, reviewed, approved, and released.
• Monitor project schedules, engineering deliverables, milestones, and key performance metrics to support on-time project completion.
• Track design release status, prototype builds, testing activities, and production readiness.
• Ensure engineering documentation, drawings, and specifications comply with company drafting standards and revision control requirements.
• Support mechanical engineers with prototype builds, manufacturing documentation, and design verification activities.
• Coordinate with Manufacturing, Quality, Supply Chain, and Production to implement engineering changes and support new product introductions.
• Assist with configuration management throughout the product lifecycle, ensuring product structures and documentation remain accurate and traceable.
• Develop and maintain project dashboards, schedules, and status reports for engineering leadership.
• Identify opportunities to improve engineering workflows, documentation practices, and change management processes.

Requirements

• Associate's or Bachelor's degree in Mechanical Engineering, Mechanical Engineering Technology, Aerospace Engineering, or a related technical discipline
• At least two years of experience creating and maintaining detailed mechanical drawings, assemblies, and manufacturing documentation using CAD software.
• Experience generating production-ready engineering drawings including dimensioning, tolerancing, and GD&T in accordance with company standards.
• Execute drawing revisions and engineering change orders (ECOs) to support ongoing product development and manufacturing.
• Experience developing and updating bills of materials (BOMs), assembly instructions, and release packages.
• Experience collaborating with mechanical engineers to convert conceptual and 3D designs into complete fabrication and manufacturing documentation.
• Experience with Product Lifecycle Management (PLM), Product Data Management (PDM), or Enterprise Resource Planning (ERP) systems.
• Strong organizational, analytical, and problem-solving skills.
• Excellent communication and cross-functional coordination abilities.
• Proficiency in Microsoft Excel, Project, and other project tracking tools.
