Firmware Engineer

该职位来源于猎聘 Firmware Engineer: Analyzes, designs, programs, debugs and modifies software. Troubleshoots code for firmware (IC embedded code) applications. Work often involves analog and digital hardware and software operating systems. Position requires knowledge and exposure to hardware design. Typically programs in machine language, assembly language and high level languages (e.g., C, C++).

Job Responsibilities

Develop embedded firmware for optical modules (e.g., QSFP-DD, OSFP, CFP). Develop software tools to support efficient debugging, validation, and lab testing. Support cross-functional teams in firmware verification, validation, and troubleshooting, including RMA analysis of field issues. Maintain and enhance the firmware codebase, including documentation, version control, and firmware upgrade management. Collaborate closely with hardware, optics, and test engineering teams to ensure product performance, reliability, and compliance with specifications. Qualifications and requirements Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Automation, Telecommunications, or a related field. Minimum 2 years of hands-on experience in embedded firmware development. Strong proficiency in C programming for MCU and embedded systems. Experience with Git or similar version control systems. Experience with at least two development environments such as SEGGER, IAR, Keil, CrossWorks, or GCC. Solid understanding of communication interfaces such as I²C, SPI, and MDIO. Experience with Python or C# for developing tools, GUIs, or test scripts. Good English proficiency for reading technical specifications, IC datasheets, and writing documentation. Strong communication and teamwork skills, with the ability to collaborate across functions. Experience in assembly language programming is a plus. Basic knowledge of circuit design and PCB layout is a plus. Experience in closed-loop control algorithm development is a plus. Familiarity with RTOS or multi-threaded firmware architectures is a plus. Familiarity with optical communication standards (e.g., CMIS 3.0–5.x, SFF-8636) is a plus. Familiarity with CFP, QSFP, and OSFP specifications and protocols is a plus. Understanding of coherent and PAM4 optical modules (active and passive) is a plus.
