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 (i.e., 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

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

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

Solid understanding of manufacturing process capability and material-driven tolerances across common automotive components, including: Stampings (steel and aluminum): spring back, forming variation, trim tolerance, and hemming effects; Castings (HPDC, LPDC, sand): draft, wall-thickness variation, shrink, machining stock, and post-machining datums; Injection-molded plastics: material shrink, warpage, fiber orientation, tooling condition, and environmental influences; Extrusions: profile variation, twist, bow, and cut-length tolerances

Preferred

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

Familiarity with craftsmanship targets, including flush, gap, and visual quality requirements

Experience supporting low-volume programs or new product launch environments
