Digital Pre-Assembly (DPA) & Dimensional Variation Analysis (DVA) Engineer

Location: Chennai
Experience: 3–5+ Years
Qualification: B.E./B.Tech – Mechanical / Manufacturing Engineering or related
Open Position : 02

Role Overview

We are looking for a DPA & DVA Engineer to support ATP products using virtual build and dimensional variation simulation to assess assembly feasibility, dimensional variation, fit, function and appearance before physical builds.

Key Responsibilities

• Perform Digital Pre-Assembly (DPA) feasibility checks for fitment, assembly sequence, accessibility, clearance, interference and installation/removal.
• Conduct static and dynamic clash checks for parts, tools, fixtures, fasteners and the surrounding vehicle environment.
• Perform virtual ergonomic checks covering operator reach, hand clearance, line of sight, posture, tool accessibility and assembly/service feasibility.
• Interpret GD&T per ASME Y14.5 and review datum schemes; identify Critical-to-Function (CTF) and Critical-to-Quality (CTQ) characteristics.
• Perform dimensional stack-up and Monte Carlo/statistical variation analysis to predict gap, flushness and fit outcomes.
• Validate simulation predictions against CMM, optical and laser scanning data and refine variation models.
• Identify high-risk dimensional conditions and recommend design/process changes to reduce variation and improve fit and finish.
• Support DFMEA, DVP&R, PPAP, virtual build and launch readiness reviews; prepare issue reports and track issues through closure.

Mandatory Technical Skills

• Strong knowledge of GD&T, datum schemes and statistical tolerancing methods including worst-case, RSS and Monte Carlo.
• Hands-on experience with DVA software such as 3DCS, VSA, CETOL or similar.
• Proficiency in CAD software such as CATIA, NX or Creo for datum and tolerance review.
• Familiarity with CMM, laser scanning and optical metrology for simulation validation.
• Good understanding of virtual build, assembly feasibility and dimensional variation analysis.
• Strong analytical, problem-solving and cross-functional communication skills.

Preferred Skills

• Automotive experience in Body-in-White, closures, interior trim or powertrain applications.
• Knowledge of Six Sigma / DMAIC methodology.
• Familiarity with Teamcenter / Windchill and drawing release processes.
• ASME GDTP certification is an advantage.

Candidate Profile

DVA/Dimensional Engineering professional with 3–5+ years of relevant experience, strong GD&T and statistical tolerancing fundamentals, hands-on variation simulation capability and the ability to communicate dimensional risks and countermeasures effectively.
