Description

As a firmware engineer in haptics, you will work on all stages of the product development cycle with a vertically-integrated technology team. You will bring up proof-of-concept prototypes and demos to help Design teams explore and evaluate new interactions. To ensure we craft well-considered features, you will architect low-latency, end-to-end haptics solutions with touch/force sensors by collecting requirements, constructing block diagrams, and reviewing hardware schematics; you will also negotiate and specify communication protocols, operating modes, and feature requirements with software driver teams. You will develop and document firmware features on prototype hardware and custom silicon, integrating actuator control algorithms with tight real-time requirements using DSP concepts, while working with factory teams to meet test and calibration requirements. To meet our especially high quality bar, you will bench-test firmware to ensure it meets performance, power, and thermal requirements; and you will debug and root cause issues with QA to deliver high-quality, robust firmware to production
