Job description

Summary

At Meta, we aim to bring together cross‑disciplinary minds in one place to deliver on our mission: build tools that help people feel connected, anytime, anywhere. As a Thermal Design Engineer, you will take a critical role in developing systems for wearables and/or new technology initiatives. You will be part of a team exploring and developing products over the full lifecycle, from prototypes to mass‑production. You will work as part of a cross‑functional team requiring collaboration in domains inside and outside thermal and fan engineering. This role intersects many disciplines, including mechanical, electrical, and software engineering. Proven experience in solving complex problems, embracing ambiguity, and proactively identifying solutions while working with a wider team is essential.
