• Support highly compact products requiring efficient integration of PCB board stacks and electronic components.
• Support both fiber and Power over Ethernet (PoE) product configurations.
• Design products capable of operating in approximately -40°C to 75°C ambient environments.
• Develop passive cooling solutions for products operating without internal fans.
• Integrate aluminum extrusions and heatsinks into chassis designs to effectively dissipate heat.
• Design for mechanical requirements including shock, vibration, thermal performance, manufacturability, and long-term reliability.

Thermal Design & Analysis

• Perform thermal calculations and simulations to validate enclosure and heatsink designs.
• Evaluate heat transfer paths and determine how to efficiently remove heat from densely packaged electronics without fans.
• Support product designs where internal temperatures may reach approximately 85°C to 95°C.
• Utilize FLOEFD or similar thermal simulation software when applicable.
• Review thermal results during prototype and design validation testing and make mechanical modifications as necessary.

PCB & Mechanical Integration

• Collaborate closely with electrical engineers and PCB layout resources to integrate electronics into mechanical designs.
• Define PCB board outlines, keep-out areas, component clearances, and mechanical constraints.
• Provide recommendations for component placement based on heatsinking and thermal requirements.
• Transfer and review EMN and DXF files between PCB layouts and 3D mechanical models.
• Verify component heights, placement, PCB stacking, keep-out areas, heatsink interfaces, and chassis interference.
• Support PCB and layout changes identified during prototype development and design validation.

Prototype, Validation & Product Release

• Support products as they move through Design Validation Testing (DVT) and into production release.
• Review prototype units and engineering checklists to identify required mechanical design cleanup or modifications.
• Troubleshoot new mechanical and thermal issues discovered during validation.
• Update designs and documentation based on DVT results.
• Support multiple products at different stages of development, including existing rack-mount designs and new DIN-rail platforms.

CAD, Documentation & Manufacturing Support

• Develop 3D models and detailed engineering drawings using PTC Creo 10.
• Maintain CAD models, drawings, and product information within PTC Windchill.
• Generate manufacturing drawings and STEP/STP files for product release.
• Develop assembly drawings and Bills of Materials (BOMs).
• Support engineering documentation and releases within Agile PLM.
• Develop drawing packages that can be effectively communicated to external manufacturing partners.
• Collaborate with manufacturing resources, including international factory teams, to support design transfer and production.

Sustaining Engineering

• Provide ongoing mechanical engineering support for products already in production.
• Support Engineering Change Requests (ECRs) related to alternate components, supplier issues, manufacturing challenges, and product improvements.
• Evaluate the mechanical and thermal impact of component substitutions.
• Troubleshoot manufacturing and vendor-related issues and implement appropriate design changes.

Top Technical Qualifications The strongest candidates will bring experience in three key areas:1. Thermal Management & Passive Cooling
