Job description

We are seeking a motivated and detail-oriented Thermal Design Engineer to join our engineering team. In this role, you will contribute to system-level thermal management solutions, leveraging simulation tools and hands-on laboratory testing to bring high-performance products from concept to production.

Responsibilities/Skills:

• Thermal Modeling & System-Level Design: Develop component and system-level thermal models using SolidWorks Flow Simulation to predict steady-state and transient thermal behavior.
• Assist in the design and integration of thermoelectric coolers into a full thermal management system, including heat sinks, interface materials, and fans.
• Conduct trade studies to optimize thermal performance, weight, cost, and reliability.
• Prototype Testing & Validation: Design, set up, and execute thermal test plans for prototype assemblies.
• Utilize lab equipment (thermocouples, data acquisition systems, thermal cameras, power supplies) to collect accurate performance data.
• Analyze test results against simulation models to validate accuracy, identify discrepancies, and iterate on designs.
• Collaboration & Documentation: Collaborate with mechanical, electrical, and systems engineers to ensure thermal constraints are met without compromising overall system functionality.
• Document simulation findings, test reports, and design recommendations in clear, concise technical memos.
