Haptics Firmware Engineer

Come join a tightly-integrated team of hardworking engineers to deliver world-class haptic experiences that will be enjoyed by millions of customers. In this role you’ll collaborate with teams across the company, including Hardware, Software, QA, and Design. 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 Minimum Qualifications + B.S. in CS/CE/ECE or related fields and 3+ years relevant industry experience + Expertise in C or C++ for embedded systems + Experience interfacing microcontrollers with sensors and actuators (e.g. LRA, VCA, Piezo) + Knowledge of embedded peripherals / protocols (e.g. DMA, USB, UART, SPI, I2C) + Ability to apply software best-practices to firmware design in bare-metal or RTOS environments + Board bring-up and debug skills with JTAG, mixed-signal oscilloscopes, and/or logic analyzers + Experience and enthusiasm for leveraging AI-powered development tools to streamline daily workflows, accelerate coding and debugging, creating test frameworks and improve overall code quality and testing Preferred Qualifications + M.S. with advanced courses in Embedded Systems, Controls, and/or Signal Processing + Working knowledge of closed-loop control systems and experience implementing low-level control algorithms in embedded environments preferred + Development of production DSP or FPGA firmware for haptic or audio applications preferred Apple is an equal opportunity employer that is committed to inclusion and diversity.
