Job（岗位）: Firmware Engineer, Facebook Reality Labs

Type（岗位类型）: Engineering | Hardware

Citys（岗位城市）: Remote, US

Date（发布日期）: Before 2021-12-14

Summary（岗位介绍）

At Facebook 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 Firmware Engineer, you will architect, design, build and test firmware systems for future AR, VR, Portal, or New Technology Teams. You will join a world-class team of experts exploring new concepts through rapid prototyping. Firmware Engineering for FRL’s device systems spans multiple target classes, requiring deep collaboration across engineering disciplines (electrical, mechanical, optical, firmware and software) and directly impacting user immersion. Our ideal candidate wants to quickly solve problems, generate big ideas, work in new technology areas, drive concepts into prototypes, and envision how those prototypes transition to high-volume consumer products. In this role, you are expected to participate in the definition of architecture and implementation of architecture in both prototype and shipping consumer products as well as demonstrate good development practices and seamless collaboration.
