Position Overview

Our client is seeking a hands-on Mechanical Designer to support the design, prototyping, and manufacturing of precision mechanical systems. This role combines 3D CAD modeling, opto-mechanical assembly design, vendor collaboration, and prototype testing in a fast-paced, interdisciplinary engineering environment. The ideal candidate thrives in a lab and shop setting, enjoys solving complex mechanical challenges, and has a strong foundation in design for manufacturing and mechanical documentation.

Essential Functions

• Design and detail mechanical and opto-mechanical assemblies using 3D CAD modeling software.
• Develop detailed engineering drawings with appropriate tolerancing and geometric dimensioning and tolerancing (GD&T) principles.
• Interface with machine shops and fabrication vendors to source precision mechanical components and support vendor management activities.
• Assemble and test mechanical system prototypes, performing hands-on troubleshooting and root cause analysis.
• Develop, document, and update manufacturing work instructions and standard operating procedures (SOPs).
• Partner with manufacturing and production teams to resolve technical issues, improve process efficiency, and support continuous improvement initiatives.

• Associate degree in Mechanical Engineering or equivalent hands-on mechanical design experience.
• Working knowledge of 3D CAD modeling tools (such as SolidWorks or similar parametric CAD platforms).
• Understanding of materials science fundamentals and manufacturing processes (machining, fabrication, assembly methods).
• Experience working in cross-functional or interdisciplinary engineering teams.
• Comfortable in a hands-on engineering environment, including use of shop tools, lab equipment, and mechanical test setups.
• Strong written and verbal communication skills for technical documentation and collaboration.
• Highly detail-oriented with strong organizational and time management skills.

• Bachelor’s degree in Mechanical Engineering or Opto-Mechanical Engineering.
• Proficiency in SolidWorks CAD software, including advanced part and assembly modeling.
• Working knowledge of GD&T and tolerance stack-up analysis.
• Experience designing, building, and testing opto-mechanical systems.
• Knowledge of design for manufacturing (DFM) and design for assembly (DFA) principles.
• Basic familiarity with optical metrology techniques, including interferometry and related precision measurement methods.
