Role Summary

As part of the PDSA (Product Design Simulation Analysis) Thermal team, you will be a key technical contributor shaping product direction through systems-level thermal engineering. You will lead thermal ownership from early concept planning and trade-offs to detailed implementation, working in tight collaboration with cross-functional partners.

You will establish scalable evaluation methods and toolchains to assess thermal behavior across each stage of development. By translating user stories into measurable requirements and actionable design criteria, you will define an end-to-end thermal strategy and drive it to closure through data-driven modeling, simulation correlation, and targeted validation—reducing risk, improving predictability, and accelerating informed decisions.

Responsibilities

• Own end-to-end thermal design from early concept/architecture trade-offs through detailed implementation.
• Translate user stories and platform power scenarios into thermal requirements, constraints, and success criteria.
• Drive early risk identification and design direction through data-driven analysis and simulation.
• Correlate simulation to validation results and continuously improve model fidelity and prediction confidence.

Requirement

• Master’s degree in Mechanical Engineering, Thermal Engineering, or a related field.
• At least 3 years+ experience as a thermal engineer in design and validation.
• Strong understanding of thermal management principles, heat transfer, and fluid dynamics.
• Extensive experience in thermal experiment design and setup.
• Experience with thermal simulation tools such as FloTHERM XT, or similar.
• Deep understanding of thermodynamics, fluid dynamics, and heat transfer principles.
• Authentic curiosity paired with a strong sense of design responsibility.

Preferred Qualifications

• Familiar with hardware and software integration for thermal management solutions.
• Familiar with mechanical design and building mockups, including experience with prototyping and evaluating physical models for thermal performance.
• Proficiency in setting up and working within RF (Radio Frequency) environments.
• 5 yrs+ working experience as a thermal engineer in design and validation.
