Responsibilities

  • Design and develop embedded firmware subsystems.
  • Implement modern C++ modules within the existing embedded architecture.
  • Develop low-level firmware for STM32 Cortex-M4F microcontrollers.
  • Build and maintain device abstraction layer drivers.
  • Extend USB stack functionality for CCID credential readers.
  • Develop ETL-based state machines.
  • Optimize firmware for memory, timing, and power consumption.
  • Debug and resolve firmware issues.
  • Implement robust fault handling and recovery.
  • Participate in firmware validation and production release.
  • Collaborate with cross-functional engineering teams.
  • Maintain firmware documentation and design artifacts.

Technical Environment

  • Modern C++ (C++17+)
  • Zephyr RTOS
  • STM32G474
  • Cortex-M4F
  • USB
  • UART
  • SPI
  • I2C
  • GPIO
  • DMA
  • Timers
  • ETL
  • CCID
