Firmware Engineering Intern

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

ODSP PHY SW Team works on Marvell's Networking PAM4 DSPs for use in data center optical modules. The SW team owns all the SW components that interacts with the DSPs, including embedded FW, customer SDK, lab test, and QA. The SW team is a critical part of the product development flow and is the go to group for getting things done, whether in the field or the lab.

Marvell's DSPs are used in 100G to 1.6T optical modules in every major cloud data center around the world. Even the data used for this job description has travelled through many of Marvell's DSPs to reach your computer, and our products are a key part of the biggest AI clusters that power all the latest generative AI projects.

Interns are paired with a mentor who supports them throughout the internship, offering guidance and ongoing feedback on their performance and development. They also have the opportunity to attend a variety of networking events, where they can connect with fellow interns and engage with team members across the organization.

What You Can Expect

• Developing embedded C firmware for controlling DSP HW
• Developing C & Python test code for utilities, GUIs, regression, and simulation infrastructure
• 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:

• 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.
• 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

• Must be a last-year master's student of Computer Science, Software Engineering, Electronics, Mathematics, Physics, or a similar technical field, enrolled at an accredited Italian university, or a recent (graduated in the last 12 months) master's graduate.
• ​Understanding the fundamentals of micro-controller 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.
• Basic understanding of how a processor interacts with memories and peripherals
• Experience in C and Python, with knowledge of git, Linux, makefiles, gdb, IDEs, and bash a plus
• Experience with the software development flow, from issue tracking (Jira), SCM (gitlab), design & code reviews (also gitlab), continuous integration (Jenkins), and regression testing is a plus
• Software development experience in Embedded Firmware environments is a plus
• Understanding of DSP concepts (equalizers, filters, ADC, DAC, FFE, DFE) and PAM modulation is a plus
• Must be curious and driven to learn more about this complicated field.
• Good verbal and written communication skills in English.
• Excellent problem-solving skills.
