Firmware Engineer

The Firmware Engineer will be responsible for developing and maintaining firmware for HID devices using ARM Cortex-M and RISC-V MCUs. This role involves designing, implementing, and maintaining embedded firmware for HID devices. The engineer will develop USB HID, BLE HID, and 2.4Ghz proprietary HID protocols, implement firmware update mechanisms and bootloader support, implement and control RGB LED lighting effects and develop firmware for driving and updating LCD displays. They will conduct performance tuning, code optimization, and power efficiency improvements. Collaborating with cross-functional teams in hardware, software, QA, and PM to deliver high-performance HID peripherals such as gaming keyboard, mice across USB, BLE and proprietary 2.4G protocols.

Must Have

• 3+ years of experience in embedded firmware development.
• Proficiency in C/C++ and real-time embedded systems development.
• Familiarity with communication Interface/protocol such as USB, SPI, I2C, Proprietary 2.4G and BLE.
• Proficient with debugging tools such as JTAG/SWD, oscilloscopes, and protocol analyzers.

Good to Have

• Knowledge of USB-IF certification process and HID descriptor design.
• Experience with CI/CD for embedded systems (e.g., Jenkins, GitLab CI).
• Familiarity with power profiling tools and energy-aware design.

General Purpose:

We are seeking a skilled and motivated Firmware engineer to join Corsair firmware team. In this role, you will be responsible for developing and maintaining firmware for HID device using ARM Cortex-M and RISC-V MCUs. You will work closely with cross-functional teams in hardware, software, QA, and PM to deliver high-performance HID peripherals such as gaming keyboard, mice across USB, BLE and proprietary 2.4G protocols.

Position Summary, Responsibilities, and Expectations:

• Design, implement, and maintain embedded firmware for HID devices based on ARM Cortex-M and RISC-V platform
• Develop USB HID, BLE HID, and 2.4Ghz proprietary HID protocols.
• Collaborate with hardware engineers to define MCU selection, pin mapping, and schematic validation.
• Implement firmware update mechanisms(e.g., DFU over USB) and bootloader support.
• Implement and control RGB LED lighting effects, include animations, brightness control, and synchronization with host software.
• Develop firmware for driving and update LCD displays, include UI rendering, menu navigation, and real-time data display.
• Conduct performance tuning, code optimization, and power efficiency improvements.
• Write and maintain clean, modular, and reusable code in C or C++
• Work closely with manufacturer to define test strategies and automate validation where applicable.
• Maintain documentation for firmware architecture, APIs, and versioning
