Position: Dimensional Variation Analysis (DVA) Engineer

Work Experience: 3 to 6 Years

Required Software Experience: DVA software such as 3DCS, VSA (Variation Simulation Analysis) and SolidWorks, CATIA, NX, Creo, or AutoCAD

Education: Bachelor's degree in Mechanical Engineering, Manufacturing Engineering or related field

Work Location: Chennai

1. Solid understanding of GD&T; (ASME Y14.5) and statistical tolerancing methods
2. Hands-on experience with DVA software such as 3DCS, VSA (Variation Simulation Analysis),
3. Proficiency in CAD software (CATIA, NX, Creo) for datum and tolerance review
4. Hands-on experience in VisMockup / Teamcenter Visualization for CAD review, sectioning, measurement, clearance, interference and virtual assembly checks.
5. Collect and review required input data such as CAD assemblies, product structure, installation sequence, process assumptions, tooling concepts, fastener details and packaging constraints.
6. Collect necessary input data such as CAD (part & assembly), datum schemes, drawings, BOP/BOD,



process flow and program assumptions from the design/VOME team.
7. Interpret and apply GD&T; per ASME Y14.5 to component drawings and datum schemes as inputs to the variation model.
8. Identify Critical-to-Function (CTF) and Critical-to-Quality (CTQ) characteristics and flag high-risk dimensional stack-up conditions early in the design phase.
9. Support Design Failure Mode and Effects Analysis (DFMEA) by quantifying dimensional risk contributions.
10. Document DVA reports, datum strategies and simulation outcomes for design reviews, DVP&R; and PPAP support. Support cross-functional teams during prototype builds, launch and production ramp-up to troubleshoot dimensional non conformances.
11. Create engineering issue presentations (PPT/Camtasia) with proposed engineering solutions for clients
12. Good understanding of automotive product structure, assembly process, manufacturing feasibility and serviceability requirements.
