About The Position

As a Dimensional Engineer at Orion Assembly, you will support the launch and long-term dimensional integrity of the T1XX-X programs. Initially focused on either the A-side or B-side of the Body Shop, you will expand your scope as the build progresses, ultimately supporting both sides of the system. Working under the guidance of the Lead Dimensional Engineer, you will help establish robust measurement systems, validate tooling and fixtures, and ensure dimensional alignment across Paint and General Assembly (GA). This role is critical not only during launch but also in steady-state production, where you will maintain dimensional stability, support supplier quality, and mentor emerging talent. You will be expected to engage with suppliers to request and validate dimensional data, occasionally traveling to support build events and quality reviews. Your work will directly influence A, B, and C metrics, and contribute to the overall quality of the vehicle.

Requirements

3+ years of experience in automotive manufacturing or dimensional engineering or related experience.
Bachelor’s degree in engineering, manufacturing, or a related field (or equivalent experience).
Solid understanding of GD&T principles and vehicle body build processes.
Familiarity with CAD software and ability to interpret dimensional data.
Working knowledge of A, B, C metrics and variation analysis tools.
Ability to work effectively in cross-functional teams and contribute to shared goals.
Experience with root cause analysis and Practical Problem Solving (PPS).
Commitment to quality and continuous improvement.
Strong written and verbal communication skills.
Ability to mentor and train technical roles, including Tech 5-dimensional team members.
Flexibility to work different shifts as needed is required
