Senior Tooling Engineer

About Adcole

Adcole has been designing and manufacturing precision measuring machines since 1957. Our systems measure cylindrical and rotating components - EV drive and rotor shafts, camshafts, crankshafts, pump shafts, and robotic reducer shafts - for customers across automotive, heavy- and medium-duty diesel, and industrial machinery markets. Manufacturers including Ford, GM, Caterpillar, John Deere, Cummins, Toyota, Honda, BMW, VW, Stellantis, SAIC, and Formula One teams such as Red Bull and Ferrari rely on Adcole systems as the gage of record for their components.

We're headquartered in Marlborough, Massachusetts, with about 100 employees across five global locations. All manufacturing happens in Massachusetts, and we ship to customers worldwide. It's a long-tenured team - people here tend to stay and build careers.

We're looking for a hands‑on Senior Tooling Engineer to take ownership of the custom tooling and fixturing used across our precision metrology systems and special projects. This is a good fit for someone with real experience in tooling, fixturing, GD&T, precision machining, and shop‑floor problem solving.

You'll work closely with Sales, Engineering, Assembly, Test, vendors, and customers - defining tooling solutions, supporting quotes, sourcing components, troubleshooting build and test issues, and making sure tooling is properly documented from concept through customer acceptance.

This is an individual contributor role with lead‑level scope. Over time, it's meant to grow into the go‑to technical resource for tooling applications at Adcole.

• Ownership of a critical tooling function, with real visibility and decision‑making authority
• Complex, custom, low‑volume work - not repetitive production runs
• Direct involvement in high‑precision metrology systems used by customers worldwide
• Close collaboration with experienced machinists, engineers, assembly, test, and sales teams
• A stable, Massachusetts‑based manufacturer with a long‑tenured workforce

• Interpret complex GD&T‑based manufacturing drawings to define tooling requirements that support sub‑micron measurement of customer components
• Lead the design, development, and lifecycle management of custom applications, including camshaft/crankshaft timing, orientation, fixturing, and critical fits
• Develop detailed manufacturing drawings and assemblies using parametric 3D modeling software such as Inventor or Solid Works
• Specify and support custom tooling, including precision headstock drive centers, tailstock centers, calibrated master artifacts, and measurement probes
• Make independent decisions on materials, tolerances, fits, and tooling modifications

• Lead tooling quote development based on customer requirements
• Provide tooling scope, assumptions, risks, and summary notes to the Sales team
• Communicate directly with customers to clarify technical requirements
• Support new opportunities by identifying tooling needs and feasibility considerations
• Support customers on major OEM‑specific engineering and spare part documentation

• Source standard and custom machine tool components
• Identify and manage key vendors for specialized tooling needs
• Evaluate make‑vs‑buy decisions
• Coordinate modifications such as milling, grinding, finishing, or customization of tooling components

• Provide hands‑on support during assembly, testing, and customer acceptance
• Diagnose tooling‑related issues involving fit, alignment, function, and performance
• Act as the primary tooling resource for shop‑floor questions and special applications
• Support special projects that fall outside standard gage sales

• Maintain the tooling drawing database, tooling numbers, and serial number records
• Organize tooling files, quote folders, historical tooling records, and BOM documentation
• Support tooling BOM creation and production release in Syteline or a similar ERP system
• Draw on historical tooling and prior builds to support repeat or similar applications

• Bachelor of Science in Mechanical Engineering
• 7–10+…
