Dimensional Engineer

CAD & 3DX Interrogation: Practical expertise using CATIA V6 and 3DEXPERIENCE (3DX) to visualize, manipulate, and interrogate 3D models for dimensional evaluation, creating reference geometry (planes, points), and mapping critical functional datums. Datum & Tolerance Design: Establish robust datum schemes, sensor mounting locator strategies, and tolerance allocations to ensure sensor-to-body and sensor-to-sensor co-calibration stability.

Our Client, an AV Manufacturing company, is looking for a Dimensional Engineer for their Foster City, CA location.
 
Responsibilities:

• Multi-Program Ownership: Serve as the ultimate dimensional authority for sensor integration across parallel vehicle platforms, successfully managing massive architectural workloads concurrently.
• Functional Requirements Definition: Lead the upfront definition of vehicle build and commodity-specific functional requirements to establish an ironclad baseline for downstream DVA validation.
• Datum & Tolerance Design: Establish robust datum schemes, sensor mounting locator strategies, and tolerance allocations to ensure sensor-to-body and sensor-to-sensor co-calibration stability.
• Fixture Design & Approval: Review and formally approve internal and supplier metrology fixture concepts, ensuring alignment with strict program assembly and measurement metrics.
• Measurement & Metrology Strategy: Define and implement comprehensive measurement strategies, identifying critical validation points from the single part level up to full vehicle assembly.
• Supplier PPAP & Collaboration: Partner directly with Supplier Quality (SQ) to evaluate supplier capability, define acceptable limits, and manage engineering escalations to protect program targets.
• Cross-Functional Feedback: Provide active architectural loop feedback regarding layout changes needed to make the vehicle body and sensor brackets reliably assemblable.

 
Requirements:

• Autonomous Sensor Architecture: Deep understanding of the unique dimensional, structural, and alignment requirements of AV sensor suites (LiDAR, Radar, Cameras).
• Advanced Variation Analysis: Proficiency in performing both 1D and 3D Dimensional Variation Analysis (DVA) stack-ups to evaluate design feasibility
• GD&T Expertise: Advanced-level proficiency in ASME Y14.5 GD&T principles, with a proven track record of creating, validating, and optimizing complex technical drawings.
• CAD & 3DX Interrogation: Practical expertise using CATIA V6 and 3DEXPERIENCE (3DX) to visualize, manipulate, and interrogate 3D models for dimensional evaluation, creating reference geometry (planes, points), and mapping critical functional datums.
• Manufacturing & Assembly Insight: Strong foundational knowledge of manufacturing processes and vehicle assembly sequence.
• Communication & Technical Leadership: Ability to translate complex statistical variation data into clear, actionable architectural feedback for cross-functional teams and executive leadership.
• Required Experience & Attributes:
• Experience: 8 to 10 years of dedicated experience in dimensional management, variation simulation, or metrology within the automotive, aerospace, or autonomous robotics sectors.
• Education: Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Fixture Design Engineering, or a closely related technical field.
• Statistical Rigor: Strong understanding of Variation Simulation Analysis tools, statistical process control (SPC), and basic statistical concepts (CP,CPK, standard deviation, gauge R&R studies).
• AV Mindset: A proactive, solutions-oriented professional who thrives in a fast-paced environment and understands that sensor dimensional engineering is a primary driver of vehicle safety and autonomous software performance.
