Mechanical CAD Designer

About the Role

The Mechanical CAD NX Designer will support the design, development, and packaging of Electronic Control Unit (ECU) hardware for next-generation automotive electrical architecture. This role involves developing production-ready mechanical designs and vehicle packaging solutions for ECUs and next-generation automotive electrical architecture.

Key Responsibilities

• Mechanical Design & CAD Development
• Design ECU housings, brackets, covers, heat sinks, mounting features, and related mechanical components in Siemens NX.
• Develop and lead vehicle-level packaging studies, including space claims, clearances, mounting, serviceability, harness and connector interfaces, and assembly requirements.
• Create detailed 3D models, assemblies, 2D drawings, BOMs, and engineering release documentation.
• Apply GD&T, tolerance analysis, DFM, DFA, and DFQ principles to deliver robust, manufacturable designs.
• Collaborate with hardware, electrical, thermal, EMI/EMC, validation, manufacturing, and vehicle integration teams.
• Support thermal packaging, structural assessments, prototype builds, validation, root-cause investigations, and production launch activities.
• Work with suppliers and manufacturing teams to resolve feasibility, tooling, assembly, and build issues.
• Support engineering changes, design reviews, PLM activities, and continuous product improvement.
• ECU Packaging & Vehicle Integration
• Participate in vehicle-level package studies to ensure compliance with space claim, clearance, and interface requirements.
• Influence mechanical interfaces between ECU hardware, wiring harnesses, connectors, and vehicle structures.
• Support integration of ECUs into zonal architectures, centralized compute systems, and connectivity platforms.
• Product Development & Engineering Collaboration
• Work closely with hardware, electrical, thermal, EMI/EMC, validation, and manufacturing teams throughout product development.
• Support design reviews, CAD reviews, and cross-functional engineering activities.
• Collaborate with suppliers to ensure design feasibility and manufacturability.
• Incorporate Design for Manufacturing (DFM), Design for Assembly (DFA), and Design for Quality (DFQ) principles into component designs.
• Support engineering change management and continuous product improvements.
• Thermal, Structural & Manufacturing Support
• Support thermal packaging activities, including heat sink integration, airflow considerations, and thermal interface design.
• Documentation & Release Activities
• Generate detailed component and GD&T-compliant engineering documentation.
• Maintain BOM structures and engineering release packages.

Requirements & Tech Stack

• Experience designing mechanical components and assemblies using Siemens NX.
• Experience creating production-ready 3D models, detailed drawings, and assembly documentation.
• Knowledge of GD&T, tolerance analysis, and manufacturing processes.
• Experience supporting product development from concept through production.

Qualifications

• Bachelor's degree in mechanical engineering, Mechanical Engineering Technology, or related field OR 10+ years of CAD mechanical design experience on automotive components.
• Strong understanding of automotive electronics packaging and ECU design.
• Strong communication and collaboration skills.
• Preferred: Experience designing automotive ECUs, modules, compute platforms, gateways, or connectivity hardware.
• Preferred: Knowledge of die-cast aluminum, plastic injection molding, sheet metal, and stamped component design.
• Preferred: Familiarity with thermal management solutions for electronic hardware.
• Preferred: Experience with automotive EMC considerations.
• Preferred: Understanding of wiring harness integration, connectors, and vehicle architecture.
• Preferred: Experience with Teamcenter PLM.
