Role Overview

We 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 robust 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
