Precision Tool & Machine Assembler – 3D CAD & Custom Automation

Location: Pewaukee, WI |
Schedule: Full-time, 1st Shift, 7:00 AM - 3:30 PM, Monday through Friday, 100% Onsite |
Compensation: Up to $40.00/hour + overtime

An established, long-standing custom automation builder in the Pewaukee, WI area is seeking a Precision Tool & Machine Assembler to join its team. This is a direct-hire, 100% onsite opportunity on 1st Shift for a skilled trades professional who thrives on complex, one-off machine building rather than high-volume line assembly. The opening was created by an upcoming long-term employee retirement, and the role offers modern, CAD-equipped workstations on the shop floor and close daily collaboration with mechanical engineers and wiremen.

• Build, fit, align, and assemble diverse, high-value custom automated machinery, robotic cells, assembly presses, and packaging lines from the ground up
• Read and build from detailed multi-view mechanical drawings, assembly blueprints, and fluid power schematics covering pneumatics and hydraulics to establish proper build sequencing
• Access 3D CAD digital models directly at shop-floor workstations to verify spatial relationships, check mechanical clearances, and inspect complex sub-assemblies in real time
• Layout, bend, route, and mount complex pneumatic manifolds, valve blocks, and high-pressure hydraulic circuits onto machine frames
• Shim, scrape, adjust, and tune precision components to exact tolerances using toolmaking-level techniques to ensure flawless mechanical motion and cycling
• Partner directly with mechanical design engineers on-site to troubleshoot assembly bottlenecks, verify tolerances, and resolve design deviations
• Oversee the breakdown, match-marking, packing, and crating of completed custom machines to prepare them for customer transport and field installation

• 5+ years of progressively responsible experience executing ground-up mechanical machine builds, OR 2+ years of experience backed by a formal background in precision toolmaking, die building, or custom fixture assembly
• Demonstrated background building high-speed material handling systems, precision automated lines, or custom packaging machinery (not component-level bench assembly)
• Expert ability to read, interpret, and assemble complex machinery directly from multi-page mechanical assembly prints and fluid power schematics involving pneumatics and hydraulics
• Expert, safe operation of hand and power tools, shop equipment (mills, lathes, surface grinders), and precision measuring instruments (calipers, micrometers, dial indicators)
• Strong interpersonal skills and a team-first work ethic to partner effectively with wiremen, controls engineers, and plant leadership
• Residence established within a 45-minute driving radius of Pewaukee, WI
• Must be a U.S. Citizen or Green Card holder

• Journeyman credentials or formal apprenticeship completion in Tool & Die or Precision Machining
• Ability to mount, align, and wire basic 24V proximity sensors, photoeyes, and limit switches during mechanical assembly
• Hands-on experience mounting and mechanically squaring end-of-arm tooling (EOAT) or camera mounting frames

• Up to $40.00/hour starting base rate, commensurate with trade experience and toolmaking depth
• Overtime availability
• Comprehensive corporate benefits package

This role offers end-to-end ownership of complex, one-of-a-kind machine builds, direct collaboration with engineering, and excellent job security in a long-standing custom automation shop.
