Key Responsibilities

Firmware Architecture & Development

• Design, develop, and maintain embedded firmware for ARM Cortex‑M and TI MCU platforms.
• Develop and optimize peripheral drivers, middleware, communication stacks, and board support packages (BSP).
• Implement modules involving ADC/DAC, PWM, DMA, timers, watchdogs, interrupts, and low‑power modes.
• Architect RTOS‑based systems using FreeRTOS or similar operating systems.
  
  

Hardware–Software Integration

• Collaborate with hardware teams for board bring-up, schematic validation, and design reviews.
• Debug hardware/firmware integration issues using oscilloscopes, logic analyzers, and JTAG/SWD.
• Validate and tune interfaces such as:
• SPI, I²C, UART, CAN, LIN
• Modbus/RS485, Ethernet, Profinet
• USB or proprietary protocols
  
  

System Optimization & Reliability

• Optimize real‑time performance, memory usage, and power consumption.
• Implement robust error-handling, diagnostics, and state-machine-driven architectures.
• Perform code reviews, static analysis, unit testing, and regression testing.
  
  

Documentation & Quality

• Prepare architectural documents, design specifications, interface definitions, and API documentation.
• Ensure firmware quality through coding standards (MISRA‑C or equivalent).
• Support validation engineers and ATE teams with firmware-level hooks and testability features.
  
  

Cross-Functional Collaboration

• Work closely with system, hardware, ATE, and validation teams.
• Provide mentorship and technical leadership to junior firmware engineers.
• Participate in system-level architecture decisions including communication frameworks, bootloaders, and security features.
