Your Team, Your Impact

As a Senior Principal Engineer, you will play a critical technical leadership role in bringing complex SERDES-based products from concept through volume production. You will be a hands-on architect and problem solver, owning embedded firmware that controls highly sophisticated DSP hardware, while leading and mentoring a team of experienced engineers.

This is a high-visibility role with direct impact on product success, silicon bring-up, customer delivery, and next-generation architecture decisions.

What You Will Do

Technical Leadership & Architecture

• Own the architecture, design, development, and testing of memory-constrained embedded C firmware controlling advanced SERDES DSP hardware
• Serve as technical lead or project lead for a product, guiding a team of 2–8 engineers from requirements through volume production
• Translate complex system and standards specifications (MSA, OIF, CMIS, customer specs) into clear firmware requirements, architecture documents, and sequence diagrams

Firmware & DSP Development

• Develop embedded firmware running on RISC-V–based multi-core MCUs
• Control and sequence proprietary DSP data paths through firmware state machines
• Convert floating-point MATLAB DSP algorithms into fixed-point firmware implementations, ensuring functional equivalence
• Design and debug robust firmware state machines, error handling, and recovery mechanisms

Debug, Validation & Bring-Up

• Lead root-cause analysis of complex HW/SW issues on real silicon and lab hardware
• Partner closely with hardware, systems, validation, and customer teams to resolve field and production issues
• Support post-silicon bring-up, simulation environments, FPGA emulation, and system validation

Collaboration & Mentorship

• Plan software milestones, drive sprint execution, close tickets, and manage releases
• Mentor junior and mid-level engineers through challenging debug and design efforts
• Influence hardware architects on next-generation design improvements based on field learnings

Travel

• Occasional international travel (~3 weeks/year) to global Marvell sites (e.g., California, Italy, Vietnam)

Minimum Qualifications (Must-Haves)

• Bachelor’s or Master’s degree in CSE, ECE, or related technical field
• 15+ years of hands-on experience in embedded C/C++ firmware development
• Strong SERDES firmware development experience (required)
• Proven experience as a Technical Lead or Software Team Lead on embedded products through customer volume production
• Deep understanding of embedded SoCs and microcontroller architectures (RISC-V preferred)
• Expertise with memory-mapped hardware, ISRs, GPIOs, bare-metal or RTOS environments
• Excellent debugging skills on real hardware in lab environments
• Proficiency with git, defect tracking tools (Jira or similar), and Linux-based workflows
• Strong written and verbal communication skills in English

Preferred / Nice-to-Have Experience

• SERDES, IM-DD or Coherent DSP, Ethernet/PCIe PHYs, Optical Module firmware
• DSP fundamentals: BER, SNR, FFTs, histograms, sampling theory, Shannon limit
• Mixed-signal control (analog + digital), PID / feedback loops
• RTOS, device drivers, Linux kernel exposure
• Python for tooling, automation, and customer-facing SDKs
• Familiarity with Verilog, FPGA emulation, or digital verification flows
• Experience using lab equipment: oscilloscopes, PNAs, ONTs, power supplies
• Understanding of networking fundamentals from PHY through Data Link layer

Why Join Marvell?

• Work on industry-leading SERDES and DSP technologies
• High-impact, senior technical leadership role
• Competitive compensation with RSUs and sign-on bonus
• Exposure to global product development and silicon bring-up

Collaborative culture that values deep technical expertise
