CAD Design Specialist CO-OP | Group 07-71 | June - November 2026

Position Description

The group seeks a program intern to assist specialist and technical staff members with cutting-edge CAD modeling to aid research and program execution in the Mechanical/Aerospace engineering. This role will provide hands-on experience in 3D modeling, drafting, and design documentation while contributing to real-world mechanical design projects. The intern will gain exposure to the full design process, from concept generation through detailed CAD modeling and drawing release.

Duties could include:

• Create and update 3D CAD models and 2D drawings of mechanical components and assemblies using SolidWorks.
• Assist in preparing detailed design documentation, including engineering drawings, bills of materials (BOMs),and revision updates.
• Support engineers in developing prototypes by providing accurate CAD data for manufacturing procurement.
• Conduct tolerance stack-up analyses, design for manufacturability (DFM) reviews, and drawing quality checks under supervision.
• Collaborate with cross-functional teams (engineering, analyst, procurement, manufacturing) to ensure designs meet requirements and standards.
• Participate in design reviews and incorporate feedback into models and drawings.
• Maintain CAD file organization, version control, and data management within the PLM system.

In addition to specific technical tasks, an employment experience at Lincoln Laboratory offers:

• The opportunity to generate real-world impact to national security and broader society through your work on challenging technology problems.
• Exposure to a broad and deep range of technologies, expertise, and senior government stakeholders.
• A strong culture of team success through individual growth. This includes technical and professional development courses, and mentorship opportunities to continue your career journey.
• A diverse workplace with an emphasis on work-life balance, employee resource groups, and other exciting opportunities.

A successful candidate:

• Will be enrolled in a degree program of study in Mechanical Engineering, Aeronautics/Astronautics, Aerospace Engineering, Civil Engineering, or Physics.
• Have completed classes or strong familiarity with 3D CAD modeling utilizing SolidWorks.
• Basic understanding of mechanical design principles, materials, and manufacturing processes.
• Strong attention to detail and ability to create accurate, clear engineering drawings.
• Good communication skills and willingness to work in a collaborative environment.
• Ability to manage multiple tasks and meet deadlines.

Preferred Skills (nice to have):

• Experience with Geometric Dimensioning & Tolerancing (GD&T).
• Exposure to simulation tools (FEA, CFD) or rapid prototyping.
• Knowledge of CAD data management systems (ARAS Innovator).

Compensation:

$25.00 - $32.00 per hour depending on years of education completed.
