Mechanical Design Engineer Jobs

About The Position

Requirements

• Degree in Mechanical Engineering or a related field, with experience in motion systems, precision mechanics, or mechatronics.
• Proficiency in Creo/SolidWorks or a similar 3D CAD modeling tool, backed by several years of work experience, along with structural, thermal, and vibration/modal FEA.
• Design-for-manufacturing (DFM) experience across machining, sheet metal, and castings; working knowledge of data-analysis tools such as Python or MATLAB.

Nice To Haves

• Experience with feedback systems involving laser interferometers and high-resolution optical encoders, linear motors, linear guides, air bearings, and similar components.
• Design experience with dynamic X-Y sub-micron positioning stages, including vibration and modal testing using accelerometers, impact hammers, and comparable instrumentation.
• Semiconductor capital-equipment design experience.

Responsibilities

• Design, develop, and maintain the mechanical architecture of next-generation multi-DOF ultra-precision motion stages that operate under high vacuum for eBeam inspection and review, taking the work from concept through detailed design, prototyping, and validation to meet nanometer-level accuracy, stability, and noise-control targets, including: Multi-degree-of-freedom stage structures, flexures, and precision motion mechanisms. Vacuum- and UHV-compatible materials and hardware with low-outgassing, contamination-controlled design. Bearing, guide, and actuation selection such as air bearings, linear guides, and linear motors. Metrology and feedback integration, including laser interferometers and high-resolution encoders. Thermal management and drift compensation for stable, repeatable positioning. Structural dynamics, damping, and vibration/noise isolation.
• Design parts and assemblies in Creo/SolidWorks and generate detailed drawings with GD&T, driving rigorous design-review and release discipline from requirements definition through validation and qualification.
• Perform structural, thermal, and vibration/modal FEA and tolerance stack-up analysis to optimize stiffness, damping, accuracy, and manufacturability, and build, test, and troubleshoot prototypes — including modal testing with accelerometers and impact hammers — to characterize dynamic performance and correlate models against test data.
• Partner closely with controls, systems, and manufacturing engineers to integrate the stage at the subsystem and system level and to improve performance, manufacturability, reliability, and serviceability.
• Own supplier technical engagement for precision parts and subassemblies — motors, bearings, encoders, and machined or cast components — including vendor selection, qualification, and issue resolution.
• Embed safety-by-design into mechanical solutions and develop service and production tooling such as jigs, fixtures, alignment tools, and handling concepts.
