Your Team, Your Impact

The Optical Digital Signal Processing (ODSP) PHY SW Team develops software for Marvell's DSP products used in pluggable optical modules-chips that form the backbone of the internet, moving data within and between data centers worldwide. Marvell is the market leader in direct-detect optical DSPs (100G to 1.6T), with products deployed in every major cloud data center and AI cluster. We own all SW components, including embedded FW, customer SDK, and lab scripts, and we're the go-to group for getting things done across the entire product lifecycle-from pre-silicon simulation through field deployment.

What You Can Expect

You will be supporting the Software team in:

• Developing Python scripts for testing, data collection, and diagnostics
• Developing embedded C firmware for controlling PAM4 DSP
• Taking an idea from concept through design, review, implementation, testing, and release to customers
• Work on mission-critical features for top-tier cloud customers
• Debug difficult issues, drive to root causes with HW/SW teams, and follow up with Jira tickets to get bugs resolved

Some possible tasks will be:

• Develop Python test scripts to configure, control, and get status from multiple DSP HW platforms for improving firmware stability
• Implement a new temperature tracking algorithm for a DSP/analog control to improve performance when device temperature changes
• Add new debug functionality to the current firmware architecture
• Breaking up a firmware routine into sub-routines with a coordinating finite state machine to manage tasks in parallel (bare metal C programming)
• Optimizing subroutines to make the best use of a multi-core MCU architecture
• Improve error management flow and reports generated by the firmware
• Implement and test serial interface for debug tracing and error reporting (UART driver)
• Scripting for system performance analysis of a customer's prototype optical module

You will gain experience with:

• Software development cycle
• Infrastructure configuration and management
• Software regression planning and execution
• Linux and Windows-based development
• Continuous Integration (Jenkins) methodologies
• Python, bash, and make scripting and automation
• Source code management (git)

What We're Looking For

• Minimum Requirements:
  • Candidate must have completed a BS/MS degree in Computer Science / Electronics Engineering or related technical field(s)
  • Experience in C and Python
  • Software development experience in embedded firmware environments based on C/C++
  • Excellent debug capability and problem-solving skills
  • Experience in data collection and analysis
  • Understanding the fundamentals of microcontroller architecture (ARM, RISC-V architecture a plus)
  • Understanding of fundamental Networking from the OSI model, with emphasis on the PHY up to the data link level
  • Must be curious and driven to learn more about this complicated field
  • Good verbal and written communication skills in English and Italian
  • Good attitude and ability to interact with remote teams

• Preferred Requirements:
  • Basic understanding of how a processor interacts with memories and peripherals
  • Experience with the software development flow, from issue tracking (Jira), SCM (gitlab), design & code reviews (also gitlab), continuous integration (Jenkins), and regression testing
  • Knowledge of Digital Signal Processing
  • Understanding of DSP concepts (equalizers, filters, ADC, DAC, FFE, DFE, PLL) and PAM modulation
  • Familiarity with closed and open loop control algorithms
  • Familiarity with the fundamentals of telecommunication and digital signal processing
  • Knowledge of git, Linux, makefiles, gdb, IDEs, and bash

Expected Base Pay Range (USD)
94,160 - 141,000, $ per annum

The successful candidate's starting base pay will be determined based on job-related skills, experience, qualifications, work location and market conditions. The expected base pay range for this role may be modified based on market conditions.

Additional Compensation and Benefit Elements
Marvell is committed to providing exceptional, comprehensive benefits that support our employees at every stage - from internship to retirement and through life's most important moments. Our offerings are built around four key pillars: financial well-being, family support, mental and physical health, and recognition. Highlights include an employee stock purchase plan with a 2-year look back, family support programs to help balance work and home life, robust mental health resources to prioritize emotional well-being, and a recognition and service awards to celebrate contributions and milestones. We look forward to sharing more with you during the interview process.

Interview Integrity

To support fair and authentic hiring practices, candidates are not permitted to use AI tools (such as transcription apps, real-time answer generators like ChatGPT or Copilot, or automated note-taking bots) during interviews.

These tools must not be used to record, assist with, or enhance responses in any way. Our interviews are designed to evaluate your individual experience, thought process, and communication skills in real time. Use of AI tools without prior instruction from the interviewer will result in disqualification from the hiring process.

This position may require access to technology and/or software subject to U.S. export control laws and regulations, including the Export Administration Regulations (EAR). As such, applicants must be eligible to access export-controlled information as defined under applicable law. Marvell may be required to obtain export licensing approval from the U.S. Department of Commerce and/or the U.S. Department of State. Except for U.S. citizens, lawful permanent residents, or protected individuals as defined by 8 U.S.C. 1324b(a)(3), all applicants may be subject to an export license review process prior to employment.
