Dimensional Engineer chez Vertex Sigma Software

Description

- 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

Requirements

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

- Familiarity with craftsmanship targets, including flush, gap, and visual quality
requirements
- Experience supporting low-volume programs or new product launch
environments
