Job Description For Firmware Engineer

• Lead the design and implementation of multi-threaded firmware architectures using FreeRTOS on ARM Cortex-M or similar MCUs.
• Develop and optimize low-level drivers for I2C, SPI, UART, and CAN protocols from scratch.
• Manage RTOS primitives including Semaphores, Mutexes, Queues, and Event Groups for thread-safe operation.
• Configure and tune the FreeRTOS scheduler, task priorities, and memory management schemes (Heap_1 to Heap_5).
• Design high-performance Interrupt Service Routines (ISRs) and implement deferred processing using task notifications.
• Implement DMA-based data transfers to offload communication overhead from the CPU.
• Conduct board bring-up and debug hardware-software interface issues using Logic Analyzers and Oscilloscopes.
• Perform stack depth analysis and memory leak detection to ensure long-term system stability.
• Implement low-power modes and tickless idle configurations within the FreeRTOS framework.
• Ensure code compliance with MISRA C standards and lead rigorous peer code reviews.
• Define and document Hardware Abstraction Layers (HAL) and API specifications for modular firmware.
• Resolve complex concurrency issues such as race conditions, deadlocks, and priority inversion.
• Optimize bootloader performance and implement secure firmware-over-the-air (FOTA) update mechanisms.
• Collaborate with hardware engineers to validate schematics and define pin multiplexing requirements.
• Manage version control workflows using Git and integrate automated testing into CI/CD pipelines.
• Mentor junior engineers on real-time systems programming and protocol debugging techniques.
• Analyze worst-case execution time (WCET) to guarantee real-time response for critical system tasks.
• Manage third-party library integration and middleware stacks (TCP/IP, USB, or File Systems).
• Drive root-cause analysis for intermittent field failures related to timing or protocol violations.
• Provide technical estimates and roadmap planning for firmware delivery milestones.
