Dimensional Engineer (GD&T & Tolerance Stack-Up)

Job Role: Dimensional Engineer – GD&T & Tolerance Stack-Up

Experience: 5+ Years

Location: Bangalore

Key Responsibilities

• Design and develop precision mechanical components and assemblies considering functional, dimensional, manufacturing, and cost requirements.
• Perform 1D, 2D, and 3D tolerance stack-up analysis to validate assembly feasibility, clearances, fits, alignment, and interchangeability.
• Conduct statistical tolerance and variation analysis to predict dimensional variation and improve assembly robustness.
• Define and optimize dimensional and geometric tolerances based on design intent, manufacturing capability, and assembly requirements.
• Create, review, and improve engineering drawings using GD&T as per ASME Y14.5.
• Establish appropriate datums, feature control frames, and geometric controls for precision components and assemblies.
• Apply DFMA principles to improve manufacturability, assembly, inspection feasibility, quality, and cost.
• Analyze and resolve dimensional, fit, clearance, alignment, and assembly issues.
• Perform root-cause analysis for dimensional non-conformities and implement corrective design/tolerance solutions.
• Collaborate with Design, Manufacturing, Quality, Supplier, and Product Engineering teams.
• Support prototype, validation, production, and continuous improvement activities related to dimensional quality.

Required Skills
