• Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, or a related field
• 3–7+ years of experience in precision wire EDM and grinding for mold/die or high-accuracy components
• Proven ability to hold ≤ ±1 µm features; experience with sub-micron or nanometer-class positioning
• Expertise machining hard metals such as carbide, H13, M1, and powder-metal steels
• Proficiency in CAM programming, GD&T, and tolerance stack-up analysis
• Hands-on experience with metrology tools, including CMMs and laser micrometry
• Ability to read mold and tooling drawings and understand injection molding components
• Knowledge of fixture design, thermal management, and precision workholding

Nice To Haves

• Experience with Moldflow analysis
• Sinker EDM experience
• Basic CNC milling and grinding experience

Responsibilities

• Program, set up, and operate machining equipment to achieve tolerances of ≤ ±1 µm
• Select grinding wheels, electrodes, wire types, and flushing strategies to optimize surface finish and cycle time
• Create and refine CAM programs using ESPRIT, G-code, and 3D CAD tools (Autodesk Inventor, NanoCam)
• Develop thermal stability processes, including fixture design and temperature compensation
• Collaborate with mold and die designers to adjust prints for true position and material shrinkage
• Build and qualify grinding wheels, electrodes, and fixtures for precision machining applications
• Perform final inspections using CMMs, laser micrometers, air gauges, and profilometers
• Implement SPC/CPK, corrective actions, and standard work procedures
• Lead DOE and Kaizen initiatives to improve tolerance capability and reduce machining cycle time
• Support toolroom operations for new builds, engineering change notices (ECNs), and urgent repairs

Benefits

• Competitive compensation based on experience
• Comprehensive health, dental, and vision insurance
• 401(k) retirement plan with employer match
• Paid time off and paid holidays
• A collaborative, innovation-driven work environment
