Job description

Responsibilities

• Own dimensional requirements from early design through production launch for assigned vehicle systems or commodities
• Develop and maintain 3D tolerance analysis (DVA) models to predict variation and assess design robustness
• Define and validate GD&T schemes aligned with functional and manufacturing intent
• Partner with Design Engineering to influence part geometry, locators, and interfaces to meet dimensional and craftsmanship targets
• Support top-down and bottom-up dimensional integration, ensuring alignment with vehicle-level requirements
• Review and approve drawings, CAD releases, and engineering changes from a dimensional standpoint
• Collaborate with Manufacturing Engineering on fixture concepts, locating strategies, and build assumptions
• Support Quality and Manufacturing teams during issue resolution, including gap/flush, fit, and alignment concerns
• Analyze build and measurement data (CMM, scan data, build reports) to validate models and drive corrective actions
• Lead or support dimensional root cause analysis, proposing effective countermeasures and design or process improvements
• Present dimensional status, risks, and recommendations in design and program reviews
• Support supplier discussions related to dimensional feasibility, tolerance capability, and corrective actions

Required Qualifications

• Bachelor’s degree in mechanical engineering, Manufacturing Engineering, or a related field
• 7-8 years of experience in dimensional engineering, tolerance analysis, or geometric integration within automotive or other high-volume manufacturing environments
• Strong working knowledge of GD&T (ASME Y14.5) with demonstrated application on production-intent designs
• Hands-on experience with 1D/3D tolerance analysis tools, such as 3DCS
• Proven experience supporting programs from concept through production launch, including detailed design, DV, PV, and SOP
• Ability to interpret CAD models, engineering drawings, and build strategies to define robust dimensional requirements
• Demonstrated experience working cross-functionally with Design Engineering, Manufacturing Engineering, Quality, and Suppliers
• Strong analytical and problem-solving skills, including dimensional root cause analysis and corrective action development
• Ability to clearly communicate technical requirements, risks, and trade-offs to diverse stakeholders
• Solid understanding of manufacturing process capability and material-driven tolerances across common automotive components, including:
  o Stampings (steel and aluminum): spring back, forming variation, trim tolerance, and hemming effects
  o Castings (HPDC, LPDC, sand): draft, wall-thickness variation, shrink, machining stock, and post-machining datums
  o Injection-molded plastics: material shrink, warpage, fiber orientation, tooling condition, and environmental influences
  o Extrusions: profile variation, twist, bow, and cut-length tolerances
• Ability to translate material behavior and process capability into realistic GD&T schemes and tolerance assumptions during design
• Experience assessing supplier manufacturing feasibility and tolerance capability during sourcing and design reviews

Preferred Qualifications

• Experience in an automotive OEM or Tier-1 supplier environment
• Experience owning or contributing to DVA / DVP / black-box tolerance models, including compliant (flexible) part modeling to represent real-world assembly behavior
• Hands-on experience modeling part compliance, locator strategies, and assembly sequence effects using 3D tolerance analysis tools (3DCS)
• Ability to apply compliant modeling techniques to assess gap/flush, fit, and functional performance of flexible components such as stampings, plastic trims, seals, and closures
• Knowledge of fixture strategy, locating schemes, and build sequence development
• Experience supporting closures, BIW, interior, or exterior systems
