Responsibilities
- Architect, implement, and maintain high-reliability embedded firmware in C and C++ for microcontroller- and ASIC-based optical modules.
- Develop low-level device control, monitoring, diagnostics, fault handling, and host-management interfaces for ASICs and external peripherals.
- Integrate firmware with lasers, photodiodes, DSPs, and module controllers to optimize optical-link performance and reliability.
- Perform hands-on prototype and board bring-up, debug cross-domain electrical and firmware issues, and investigate performance and interoperability anomalies.
- Synthesize test results, document architectural decisions, and present technical findings and project status to multidisciplinary engineering teams.
Requirements
- At least 5 years of hands-on professional embedded software development experience using C and C++.
- Experience developing firmware for microcontrollers and controllers supporting hardware diagnostics, device control, and interfaces with ASICs and external components.
- Bachelor's or master's degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent practical experience.
- Hands-on proficiency with I2C, SPI, UART, and MDIO; ability to read schematics and component datasheets; and experience using oscilloscopes, logic analyzers, and JTAG.
- Ability to work autonomously, lead technical problem-solving investigations, and communicate complex project details clearly.
- Preferred: RTOS experience in resource-constrained environments; knowledge of optical transceivers, coherent optics, high-speed SerDes, DSPs, or optical monitoring subsystems.
- Preferred: understanding of CMIS, SFF specifications, and Ethernet protocols; Python or similar scripting for test automation, hardware control, and data analysis; and experience with DVT, product qualification, or manufacturing test readiness.
