Firmware Engineering Intern

Job title: Firmware Engineering Intern

About the Role Marvell seeks a Firmware Engineering Intern to contribute to the development of embedded software for DSP hardware in data-center optical modules. Paired with a mentor in the ODSP PHY SW Team, you’ll participate in the full software development lifecycle to ship features that power high-performance networking solutions.

What You'll Do

• Develop embedded C firmware for controlling DSP HW
• Develop C & Python test code for utilities, GUIs, regression, and simulation infrastructure
• Take 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; improving 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, CI (Jenkins) methodologies, Python, bash, and make scripting, 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 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.

Nice to Have

• Experience with PAM4 DSPs or data-center optics.
• Hands-on lab testing or customer SDK experience.
• Familiarity with ARM/RISC-V microcontroller tooling and debugging workflows.
