Sr. Mechanical CAD Designer

Essential functions

• Create, maintain, and release detailed 3D models, assemblies, fabrication drawings, and engineering documentation using CAD software.
• Independently own and manage mechanical design packages and assembly-level CAD work for prototype and development systems.
• Collaborate closely with mechanical, electrical, RF, and test engineers to support integration of mechanical components within larger system architectures.
• Evaluate designs for manufacturability, assembly efficiency, tolerance accumulation, serviceability, and fabrication feasibility.
• Support prototype assembly, troubleshooting, fit-up verification, and testing activities in both laboratory and field environments.
• Coordinate with suppliers, machine shops, fabrication vendors, and internal teams to support procurement and manufacturing activities.
• Aid in the development and maintenance of CAD standards, drawing quality, BOM structure, and engineering documentation processes.
• Identify design issues proactively and recommend practical solutions to improve reliability, manufacturability, and assembly efficiency.
• Support engineering teams with fixture design, prototype modifications, and implementation of engineering changes.
• Provide guidance and technical support to junior designers and engineering support personnel as needed.
• Participate in occasional field visits to support prototype deployment, testing, and evaluation activities.

Competencies

• Advanced proficiency with PTC Creo or equivalent 3D CAD software required. Experience with Windchill or PLM systems preferred.
• Strong understanding of mechanical design principles, fabrication methods, machining processes, and mechanical assemblies.
• Working knowledge of GD&T, tolerance stack-up analysis, and engineering drawing standards.
• Experience supporting prototype development and integration in industrial, energy, manufacturing, or R&D environments.
• Strong troubleshooting and problem-solving skills with a practical, hands-on mindset.
• Ability to balance design intent with manufacturing realities and field usability considerations.
• Excellent organizational skills and attention to detail.
• Ability to collaborate effectively within multidisciplinary technical teams.
• Strong communication skills and ability to interact professionally with engineers, technicians, suppliers, and vendors.

Education and Experience

• Associate’s degree or formal technical training in Drafting, Mechanical Design, Mechanical Technology, or a related technical field required. Equivalent practical experience may also be considered.
• 5-7 years of related experience in mechanical CAD design, product development, prototype systems, or industrial mechanical design environments required.
• Experience supporting fabrication, machining, prototype assembly, or testing activities strongly preferred.
• Experience with industrial mechanical systems, pressure systems, drilling technologies, or complex electromechanical assemblies is preferred.
• Experience working within prototype-heavy or R&D-focused organizations is highly preferred.

Physical requirements

• The employee is regularly required to stand, sit, walk, stoop, kneel, crouch or crawl, as well as use hands to feel, reach, grasp, handle, or operate objects, tools and/or controls.
• The employee must be able to lift, push, pull, transfer, or move items up 20 pounds at times for departmental needs.
• Able to move from one worksite to another or light travel to various job sites and locations to complete tasks.
• The vision requirement includes reviewing written and electronic materials in digital and physical format.
