Sr. Mechanical Engineer - CNC Methods, Tooling & Fixuring

Tuuci • Hialeah, FL

2d • Onsite

About The Position

Tuuci is seeking a hands-on, technically strong Sr. Mechanical Engineer — CNC Methods, Tooling and Fixturing to lead the design and validation of tooling, fixtures, and workholding systems that support reliable CNC manufacturing. This role establishes datum and setup standards for machined parts and serves as the engineering bridge between product design intent and CNC execution.
This is a CAM-adjacent role: not the primary CNC programmer, but highly fluent in CNC process requirements, fixturing strategy, and machining readiness. The ideal candidate brings strong shop-floor credibility, sound DFM judgment, and the ability to ensure parts are machined safely, accurately, and repeatably.

Requirements

• Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, or a related field; equivalent experience considered
• 10–15+ years of manufacturing engineering experience in CNC machining environments with significant tooling and fixture design responsibility
• Strong expertise in workholding fundamentals, datum strategy, and fixture design for prismatic and cylindrical parts
• Proficiency in SolidWorks or equivalent 3D CAD for tooling and fixture design
• Ability to review G-code, CNC toolpaths, and CAM outputs; Emmegi and Haas experience preferred
• Strong understanding of machining capability, metrology, and dimensional inspection related to fixture validation
• Experience in high-mix, configurable product manufacturing environments
• Ability to create clear, shop-ready documentation including setup sheets, fixture drawings, and standard work
• Strong DFM judgment for CNC machining, including tool access, tolerancing, material behavior, and surface finish requirements
• Hands-on credibility and comfort working directly with CNC operators and machinists to solve problems in real time

Nice To Haves

• Experience with structured problem solving such as 8D, A3, fishbone, or 5-Why preferred
• Familiarity with probing or in-process inspection systems and ASME Y14.5 GD&T preferred

Responsibilities

• Design and validate production fixtures, workholding systems, and jigs for CNC machining across Tuuci product families
• Own the full fixture lifecycle: concept, design, procurement/build, validation, documentation, and revision control
• Develop standardized and modular workholding methods by part family to reduce setup time and variability
• Define datum schemes and setup standards to ensure consistency across CNC programming, inspection, and assembly
• Create setup documentation including datum references, torque specs, clamping requirements, and first-piece verification criteria
• Review toolpaths, G-code, and CAM packages to confirm fixturing assumptions and datum references are correctly applied
• Establish probing and in-process verification strategies that improve repeatability and catch issues before parts leave the machine
• Create and maintain tooling libraries with standard tools, inserts, specialty tools, and application guidelines by material
• Serve as the manufacturing engineering lead in DFM/DFA reviews for machined parts, advising on machinability, tolerances, setup complexity, and tooling impacts
• Support NPI launches by delivering validated fixtures and setup documentation ahead of pilot builds and leading first-article prove-outs with programmers and operators
• Maintain fixture design standards, setup templates, and a structured fixture library for repeatable shop-floor execution
• Lead root-cause analysis and corrective actions for CNC quality issues related to fixturing, datum strategy, or work holding
• Mentor engineers and operators through hands-on training, setup reviews, and fixture/workholding best-practice coaching
• Communicate technical information clearly and professionally across engineering and production teams

Benefits

• Welcoming friendly environment
• Culture that encourages diversity of thought
• Support for professional growth and development
• Dynamic and talented staff of creative professionals
• Collaborative environment that welcomes innovative ideas and allows you to make an immediate impact on the team
• Health benefits, matching 401k retirement plan, paid holidays, sick days, personal days
