• CMIS/C-CMIS compliance
• Bootloader architecture
• Firmware upgrade mechanisms (including hitless/in-service upgrades)
• Hardware abstraction layers
• Calibration and control engines
• Collaborate with hardware, DSP, validation, manufacturing, ATE, and test engineering teams to resolve complex system-level issues.
• Support customer engagements by troubleshooting field issues, responding to technical inquiries, and delivering firmware solutions.
• Drive firmware platform improvements, shared infrastructure development, release processes, and automation initiatives.
• Mentor engineers and provide technical leadership across multiple programs.

Required Qualifications

• 15+ years of embedded software/firmware development experience.
• Strong expertise in coherent optical module firmware (400ZR, 800ZR, ZR+, or equivalent technologies).
• Deep understanding of industry standards including:
• OIF-400ZR
• CMIS 4.x/5.x
• C-CMIS
• Experience with SoC-based embedded systems and MCU/DSP architectures.
