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
• Strong proficiency in C/C++ for embedded systems
• Hands-on experience with FreeRTOS (mandatory)
• Robust experience with CAN protocol (mandatory)
• Strong 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 / Good to Have
• Experience with Ethernet (TCP/IP stack, embedded networking)
• Exposure to industrial communication protocols or CNC/motion con
