Senior Firmware Engineer

We are seeking a Senior Firmware Engineer contractor to develop real-time embedded firmware for robotic actuator platforms and distributed control systems. The primary focus is on communication interfaces — implementing and integrating industrial and automotive protocols on ARM microcontrollers that coordinate motor controllers, sensors, and host compute across Ethernet and fieldbus networks. You will work on bare-metal and RTOS-based firmware for TI and/or NXP MCUs, owning features end-to-end from design through board-level validation.

• Design and implement firmware for 32-bit ARM microcontrollers (Cortex-R/M), focusing on communication stacks and peripheral integration
• Implement and integrate EtherCAT slave/master stacks (TI ICSS-based or equivalent) for real-time sensing and control
• Implement CAN-FD communication layers — including Cyphal (Open Cyphal/UAVCAN) protocol integration for sensor and actuator networks
• Support Ethernet connectivity firmware: MAC/PHY bring-up, LwIP or similar lightweight TCP/IP stacks, UDP streaming protocols, 100
  
  Base-T1/automotive Ethernet
• Integrate and validate sensor and motor control communication interfaces
• Perform board bring-up, peripheral validation, and firmware debug using JTAG, logic analyzers, oscilloscopes
• Write well-structured, testable C firmware with documentation appropriate for team handoff

• Embedded firmware development on 32-bit ARM microcontrollers (Cortex-M/R)
• Strong experience with communication protocol implementation
  : at least two of — EtherCAT, Ethernet (raw/UDP/LwIP), CAN/CAN-FD, RS-485/UART
• Hands-on experience with real-time operating systems (FreeRTOS, Zephyr, or similar)
• Proficiency in C for bare-metal and RTOS-based embedded systems
• Experience with DMA-driven peripheral communication (UART, SPI, CAN) for deterministic, high-throughput data transfer
