Role OverviewWe are looking for a skilled Firmware Engineer to design, develop, and maintain embedded firmware for custom hardware platforms used in CNC controller systems. The ideal candidate will have strong experience in real-time systems, hardware bring-up, and communication protocols, along with a solid understanding of embedded Linux workflows.

Key Responsibilities
Design and develop embedded firmware for custom boards used in CNC controllers
Work with FreeRTOS for real-time application development
Implement and debug communication protocols such as UART, SPI, I2C, CAN, and Serial interfaces
Develop and integrate CAN-based communication systems (mandatory)
Work on board bring-up, hardware validation, and debugging at the system level
Collaborate with hardware engineers during schematic and PCB design phases
Optimize firmware for performance, memory usage, and reliability
Debug low-level issues using tools like oscilloscopes, logic analyzers, and debuggers
Develop and maintain documentation for firmware and system design
Follow a Linux-based development workflow (build systems, toolchains, scripting, etc.)





Required Skills & Qualifications
3+ years of experience in embedded firmware development
Solid proficiency in C/C++ for embedded systems
Hands-on experience with FreeRTOS (mandatory)
Strong experience with CAN protocol (mandatory)
Robust understanding of serial communication protocols (UART, SPI, I2C)
Proven experience in board bring-up and hardware debugging (mandatory)
Experience working in a Linux development environment
Familiarity with cross-compilation, build systems (Make/CMake), and debugging tools (GDB, OpenOCD, etc.)
Familiarity with version control systems (Git)
Solid understanding of embedded systems fundamentals (interrupts, timers, memory, peripherals)

Preferred / Positive to Have
Experience with Ethernet (TCP/IP stack, embedded networking)
Exposure to industrial communication protocols or CNC/motion control systems(EtherCAT, Profinet)
Experience with bootloaders, firmware update mechanisms
Knowledge of scripting (Python, Bash)
