About the role

We are seeking an experienced Mechanical Designer to support a leading global materials science and manufacturing organization.

Responsibilities

• Transform sketches, concepts, engineering direction, and preliminary layouts into complete, manufacturable mechanical designs.
• Create detailed 3D models, assemblies, manufacturing/fabrication drawings, and assembly documentation using SolidWorks.
• Create and maintain BOMs, part specifications, and engineering documentation using SolidWorks PDM or a comparable system.
• Select and specify purchased components, standard hardware, and COTS equipment.
• Work with supply chain, procurement, manufacturing teams, suppliers, and fabrication vendors to source components and equipment.
• Apply GD&T, tolerancing, fit selection, constraint‑based design, DFM, and maintainability principles.
• Build, fit, debug, and troubleshoot prototypes and refine designs based on testing and hands‑on findings.
• Support design reviews, inspection, testing, installation, startup, and commissioning.
• Maintain drawing standards and revision control throughout the project lifecycle.

Requirements

• 5+ years of hands‑on mechanical design experience.
• High school diploma required; degree is not required.
• Proven experience designing custom equipment, tooling, fixtures, machinery, or automation systems.
• Strong proficiency in SolidWorks for part modeling, assembly modeling, drafting, and detailing.
• Experience with SolidWorks PDM or similar engineering document management systems, including BOM and revision control.
• Strong mechanical aptitude with hands‑on experience assembling, modifying, and troubleshooting mechanical systems.
• Experience using inspection tools such as calipers, micrometers, indicators, and height gages.

Preferred qualifications

• Experience in manufacturing, process development, laboratory, or production equipment design.
• Knowledge of industrial components including bearings, lead/ball screws, timing belts/pulleys, gearboxes, power transmission, pneumatics, hydraulics, structural framing, sensors, actuators, and motion control.
• Working directly with machine shops, fabrication vendors, and equipment suppliers.
• Skills in machining, welding, sheet metal fabrication, additive manufacturing, and mechanical assembly.
• Experience with prototype development, equipment installation, commissioning, and troubleshooting.
• Experience working with multidisciplinary engineering and manufacturing teams.

Why this opportunity?

You'll be working in an environment where equipment is designed, prototyped, built, installed, and tested on‑site, giving you the opportunity to see your designs move from concept through real‑world implementation.
