Senior Staff Firmware Engineer - memory constrained embedded system development/data center interconnectivity

Job title: Senior Staff Firmware Engineer - memory constrained embedded system development/data center interconnectivity

About the Role This Senior Staff Firmware Engineer will join the optics DCI Firmware team to develop memory-constrained embedded software for Marvell's high-speed coherent fiber transceivers used in data center interconnects. The role involves defining requirements, implementing and optimizing firmware features, testing, and cross-functional collaboration to deliver reliable DCI solutions.

What You'll Do

• Evaluate and define DCI firmware feature requirements.
• Design, implement and optimize DCI firmware features for reuse across products.
• Perform failure analysis using tools to identify, duplicate, and fix issues.
• Collaborate with Application/Project Management, DVT, Hardware, and Architecture teams on requirements, performance, schematics, and standards.

What We're Looking For

• Required: Bachelors, Masters, or PhD in Electrical Engineering, Computer Engineering, or related technical fields.
• 7+ years of memory-constrained embedded system development.
• 5+ years of firmware development on device drivers and peripherals like I2C, I3C, SPI, etc.
• Strong programming skills in C and Python.
• Strong understanding of RTOS.
• Understanding of embedded SoC, micro-controller architecture (RISC-V a plus), memory-mapped hardware interfaces, GPIOs, ISRs.
• Comprehension of hardware design schematics.
• Familiarity with lab equipment (oscilloscopes, multimeter, power supplies, logic analyzer) and debuggers like JTAG.
• Strong problem-solving and customer debug skills on real hardware in the lab.
• Highly effective communication and presentation.

Nice to Have

• Experience with Optical Transceivers, Coherent DSP, Laser, optical components, PID control.
• Experience with developing/debugging Linux device driver, software state machines, context saving, error handling.
• Knowledge of OIF CMIS, OSFP, SFP, optics, git, Makefile, gdb, IDEs, bash.
• Understanding of signal processing: histograms, BER, SNR, sampling phase, Shannon limit, impulse & frequency response, FFT, etc.

Compensation & Benefits

• Salary range: USD 131,010 - 196,300 per year.
• Benefits include an employee stock purchase plan with a 2-year look back, family support programs, robust mental health resources, and recognition/service awards.
