Firmware Engineer

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.
