Job description

We are seeking an experienced Dimensional Engineering professional to support automotive product development, manufacturing engineering, vehicle launch, and quality improvement activities for global OEM programs. The role is responsible for dimensional feasibility, GD&T and variation management, tolerance optimization, measurement system deployment, dimensional validation, and launch support throughout the vehicle development lifecycle, including SOP and post-launch stabilization activities. The successful candidate will work closely with Product Design, Perceived Quality (PQ), Manufacturing Engineering, Supplier Quality, Metrology, Plant Launch, Production, and OEM customer teams to ensure robust dimensional performance, achievement of vehicle quality targets, and successful product launches.

Responsibilities

Dimensional Engineering & Product Development

• Perform dimensional feasibility analysis during concept, design, development, and industrialization phases.
• Conduct Digital Mock-Up (DMU) reviews to identify dimensional risks, package constraints, assembly concerns, and manufacturability issues.
• Support design convergence by evaluating dimensional performance against engineering requirements, vehicle targets, and manufacturing capability.
• Develop and maintain dimensional control strategies and dimensional control plans for vehicle systems and assemblies.
• Define and drive achievement of vehicle-level dimensional quality targets including Gap & Flush, Flushness, Feature Relationship, and other Perceived Quality (PQ) requirements.
• Collaborate with Product Design, PQ, BIW, and GA Process Engineering teams to improve dimensional robustness and manufacturing feasibility.

GD&T, Datum Strategy & Tolerance Management

• Develop and implement robust GD&T schemes, datum structures, and locating strategies for BIW panels, BIW sub-assemblies, closure systems, GA trim parts, and vehicle integration interfaces.
• Review engineering drawings, CAD models, and technical specifications for dimensional compliance and manufacturability.
• Define functional dimensioning requirements aligned with product functionality, assembly requirements, and measurement strategies.
• Conduct 1D tolerance stack-up analysis using RSS (Root Sum Square) and Worst-Case methodologies.
• Perform tolerance optimization studies and Cost vs Tolerance trade-off evaluations balancing quality, manufacturability, process capability, and cost.

Measurement Systems, Fixtures & Tooling

• Define dimensional validation strategies and technical requirements for dimensional checking fixtures, attribute gauges, General Assembly fixtures, BIW fixtures, E-Cube systems, CMMs, and optical measurement systems.
• Support fixture concept development, supplier evaluations, procurement activities, installation, commissioning, and final buy-offs.
• Lead measurement system validation activities including fixture correlation, Gauge R&R, MSA, and capability assessments.
• Collaborate with metrology teams and suppliers to ensure measurement systems are robust and aligned with dimensional control requirements.

Vehicle Build, Launch Support & Process Capability

• Lead dimensional prove-out activities during prototype, pilot, pre-production, SOP, and post-launch (SOP + 90 Days) phases.
• Monitor dimensional performance against PIST targets, dimensional quality objectives, and BIW & GA Gap & Flush requirements.
• Drive dimensional issue resolution through structured root cause analysis, corrective actions, and production readiness assessments.
• Analyze dimensional data and evaluate process capability using Cp, Cpk, Pp, and Ppk methodologies.
• Perform variation analysis, tolerance optimization, and derogation assessments based on actual build and production data.
• Support supplier dimensional quality reviews, APQP/PPAP activities, dimensional sign-offs, and launch readiness assessments.
• Develop dimensional dashboards, reports, and trend analyses to support continuous improvement and data-driven decision-making.

Qualifications

• Bachelors Degree in Engineering in (Mechanical/Production /Automobile)
• Certifications in GD&T, Dimensional Engineering, Metrology, Tolerance Analysis, and Six Sigma preferred.
