About Marvell

Marvell’s semiconductor solutions are the essential building blocks of the data infrastructure that connects our world. Across enterprise, cloud and AI, and carrier architectures, our innovative technology is enabling new possibilities. 

At Marvell, you can affect the arc of individual lives, lift the trajectory of entire industries, and fuel the transformative potential of tomorrow. For those looking to make their mark on purposeful and enduring innovation, above and beyond fleeting trends, Marvell is a place to thrive, learn, and lead. 

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 s
