Haptics Firmware Engineer

Responsibilities

• Develop and document Taptic Engine firmware for prototype hardware, custom silicon, and production systems.
• Bring up proof-of-concept prototypes and demos to help design teams explore and evaluate new interactions.
• Architect low-latency, end-to-end haptics solutions using touch and force sensors.
• Collect requirements, construct block diagrams, and review hardware schematics.
• Define communication protocols, operating modes, and feature requirements with software driver teams.
• Integrate actuator control algorithms with tight real-time requirements using DSP concepts.
• Work with factory teams on test and calibration requirements.
• Bench-test firmware for performance, power, and thermal requirements.
• Debug and root-cause firmware issues with QA to deliver robust production software.
• Create test frameworks and use AI-powered development tools to improve coding, debugging, code quality, and testing workflows.

Requirements

• Bachelor’s degree in computer science, computer engineering, electrical or computer engineering, or a related field.
• 3+ years of relevant industry experience.
• Expertise in C or C++ for embedded systems.
• Experience interfacing microcontrollers with sensors and actuators such as LRA, VCA, or Piezo devices.
• Knowledge of embedded peripherals and protocols including DMA, USB, UART, SPI, and I2C.
• Ability to apply software best practices in bare-metal or RTOS environments.
• Board bring-up and debugging experience using JTAG, mixed-signal oscilloscopes, and/or logic analyzers.
• Preferred: master’s degree with advanced coursework in embedded systems, controls, and/or signal processing.
• Preferred: knowledge of closed-loop control systems and experience implementing low-level control algorithms in embedded environments.
• Preferred: production DSP or FPGA firmware development experience for haptic or audio applications.
