generalmotors; Warren (MI); On-site; USD 120,000 - 170,000; Full time

Job summary

General Motors is seeking a Dimensional Systems Engineer to shape vehicle assembly through robust dimensional strategies and AI-enabled insights. You will lead dimensional integration across body structures, define requirements for purchased parts, and coordinate analyses using 3DCS, VISVSA, and 3D simulation tools.

The role emphasizes mentoring teams, establishing global standards, and driving cross-functional collaboration to improve fit, function, and manufacturing efficiency in a fast-paced

Qualifications

• Bachelor’s degree in engineering.
• Curious, innovative, and continuous-improvement mindset to dimensional engineering.
• 7+ years of experience in dimensional engineering, product design/release, manufacturing engineering, supplier engineering, quality, or metrology.
• Proficiency in GD&T, ASME Y14.5, tolerance allocation, datum structures, and dimensional variation management.
• Experience with body structures, exteriors, closures, complex assemblies, automotive launches, and manufacturing processes.
• Experience with Measurement Systems (CMM, Scanning), MSA and SPC.
• Understanding of system- and subsystem-level dimensional requirements.
• Experience with UG/NX PMI and Parametric Design, VISVSA, 3DCS, SimSolid, and Teamcenter Visualization Mockup.
• Demonstrated ability to lead projects, make technical decisions, and influence cross-functional organizations without direct authority.
• Strong communication skills and the ability to explain complex technical information to engineering, manufacturing, quality, program, plant, and supplier teams.
• Flexibility and adaptability in a fast-paced environment with changing program priorities.
• Demonstrated curiosity with AI, Python, automation, PolyWorks DataLoop, or PMI integration.

Responsibilities

• Lead dimensional integration, technical reviews, risk assessments, and GD&T activities for body structures, exteriors, and closures from concept through launch.
• Define dimensional requirements for purchased components and assemblies and document them in program Statements of Requirements (SORs).
• Develop and coordinate variation and sag analyses using 3DCS, VISVSA, RSS, SimSolid, or comparable tools.
• Support supplier reviews, matching events, gage reviews, vehicle builds, launch activities, and structured issue-resolution events.
• Serve as a GD&T and dimensional-systems subject-matter expert while mentoring engineering, manufacturing, quality, plant, and suppliers.
• Establish and deploy global dimensional standards, strategies, training, best practices, and lessons learned.
• Collaborate with dimensional quality, design release, product design, manufacturing engineering, supplier quality, plant quality, program, and supplier teams to deliver robust dimensional solutions.
