About this role

At Reality Labs we aim to bring together the brightest cross-disciplinary minds in one place to deliver on our mission: build tools that help people feel connected, anytime, anywhere.

As a Thermal Design Engineering Intern, you will take a critical role in developing systems for VR, AR, Smart Glasses and Wearables, or New Technology Initiatives. You will be part of a team exploring and developing consumer electronics products over the full lifecycle, from prototypes to mass-production.

You will work as part of a cross functional team requiring collaboration and curiosity in domains inside and outside thermal engineering.

Our ideal candidate has strong heat-transfer fundamentals, is familiar with CFD theory with some fluency in tools, experienced in developing thermal/analytical models from first-principles, and testing.

This is a 12 week internship.

Responsibilities

  • Develop physics-based thermal models using programming languages such as MatLAB, Python, or Julia
  • Develop part and sub-system thermal models using CFD and CAD tools
  • Develop and optimize thermal designs while integrating new thermal technologies through partnering with mechanical and electrical engineers
  • Support sub-system and system-level thermal verification through prototype testing
  • Support the development of thermal control systems while building prototypes to test on physical HW

Qualifications

  • Currently working towards a Bachelor’s degree in Mechanical Engineering with focus on Heat-Transfer / Thermodynamics
  • Background in modeling using CAD and CFD tools
  • Experience in running thermal tests using thermocouples
  • Experience in programming with a scripting language such as MatLab, Python, or Julia, to support development of models and automation tools
  • Must obtain work authorization in country of employment at the time of hire, and maintain ongoing work authorization during employment
  • Intent to return to full-time degree program after completion of the internship Working towards a Masters or PhD with focus on Heat Transfer
  • Experience developing analytical, physics-based thermal models
  • Familiar with control theory
  • Experienced in developing physical prototypes of consumer-electronics devices
  • Familiar with thermal materials, such as graphite spreaders, aerogels, thermal interface materials, heatpipes, vapor-chambers, and fans
