Ph.D. 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

Marvell is building the silicon that makes AI possible — the custom XPUs, the 224G and 448G SerDes, the Silicon Photonics interconnects, the co-packaged optics platforms that hyperscalers depend on to train and deploy the world's most advanced models. Designing that silicon at the pace and complexity the AI era demands requires more than engineering talent. It requires intelligence applied to the design process itself. Marvell's AI and machine learning teams are working on exactly that — using AI to accelerate how silicon is designed, verified, and deployed, and building the enterprise AI infrastructure that makes Marvell's engineering organization faster and smarter at every level.

This Ph.D. intern pool spans two distinct but connected tracks. The first is hardware-focused: applying ML and AI techniques directly to chip design challenges — EDA automation, design space exploration, predictive modeling for timing and power, and AI-driven approaches to physical design and verification at advanced process nodes. The second is enterprise-focused: building and deploying the internal AI tools and platforms — including large language model integrations, agentic workflows, and AI-assisted engineering systems — that Marvell's global engineering teams use every day. Both tracks sit at the frontier of what applied AI research looks like in a production semiconductor environment, and both are grounded in problems that do not yet have off-the-shelf solutions.

Marvell's Ph.D. Intern Program places doctoral candidates directly inside these active efforts, working on problems that are inseparable from their academic research. The work done here is the applied dimension of doctoral research in machine learning, computer science, and electrical engineering — conducted at production scale, on real design data, with real consequences for the silicon that ships to the world's largest AI infrastructure operators. What you will take away is something no coursework or academic dataset can replicate: the experience of deploying your research inside one of the most complex engineering environments in the semiconductor industry.

What You Can Expect

Track 1 — AI/ML for Hardware & Chip Design

As our Ph.D. AI/ML Intern on the hardware track, every day you will apply machine learning research to real chip design problems across Marvell's advanced silicon development flow. Specifically, you can expect to:

• Develop and apply ML models — including graph neural networks, reinforcement learning, and generative approaches — to chip design tasks such as placement, routing, timing closure, power estimation, and design rule checking

• Work directly with production EDA tool flows and real design data from active tapeouts in 3nm and 2nm FinFET and Gate-All-Around processes

• Build predictive models that reduce design iteration cycles and improve first-pass silicon success rates

• Collaborate with analog, digital, and physical design engineers to identify high-value automation targets and validate model outputs against ground-truth silicon results

• Present research findings and model performance to engineering leadership and contribute to internal technical documentation

Track 2 — Enterprise AI Tools & Implementation

As our Ph.D. AI/ML Intern on the enterprise tools track, every day you will work on the deployment and integration of large language models and agentic AI systems into Marvell's engineering workflows. Specifically, you can expect to:

• Design, implement, and evaluate LLM-based tools and agentic workflows — including systems built on models such as Claude — for use by Marvell's global engineering and operations teams

• Build retrieval-augmented generation (RAG) pipelines, fine-tuning workflows, and prompt engineering frameworks grounded in Marvell's internal knowledge and tooling ecosystem

• Evaluate model performance, safety, and reliability in production enterprise environments and iterate based on real user feedback from engineering teams

• Collaborate with IT, security, and engineering stakeholders to ensure responsible and scalable AI deployment across the organization

• Present implementation results and adoption metrics to cross-functional leadership

What We're Looking For

To thrive in this role, you must have hands-on experience building and deploying machine learning systems — not just academic familiarity with the theory. Specifically:

• Currently enrolled in a Ph.D. program in Computer Science, Electrical Engineering, Data Science, or a related field, with a research focus in machine learning, AI systems, or a related area

• Demonstrate applied experience training, evaluating, and deploying ML models using frameworks such as PyTorch or TensorFlow

• Write production-quality Python; familiarity with version control (Git) and software development best practices is required

• Apply rigorous experimental methodology — you design experiments, measure results, and draw defensible conclusions from data

• Communicate technical work clearly to both research and engineering audiences — you will present your work and defend your approach to the teams you work with

Track 1 — Additional Requirements

• Coursework or research experience in VLSI design, digital or analog circuit design, computer architecture, or EDA — sufficient to understand the design problems your models are solving

• Familiarity with graph-based ML methods (GNNs), reinforcement learning, or generative models applied to structured engineering data

• Exposure to EDA tools or chip design flows (Cadence, Synopsys, or equivalent) is a strong plus

Track 2 — Additional Requirements

• Design and implement agentic GenAI systems with demonstrated experience across the full stack — LLMs, multimodal models, RAG pipelines, and agentic protocols such as MCP and A2A

• Apply hands-on knowledge of SOTA architectures and frameworks including transformers, diffusion models, and orchestration tools such as LangChain, LangGraph, AutoGen, CrewAI, LlamaIndex, or Hugging Face

• Benchmark and evaluate model performance rigorously — you identify failure modes, propose enhancements, and back conclusions with data

Preferred Qualifications — Track 2

• Experience with agentic reasoning, planning, and tool-use patterns in multi-agent orchestration frameworks such as n8n or AutoGen

• Exposure to end-to-end data pipeline development and model deployment in collaboration with data engineering or platform teams

• Demonstrated ability to independently research and implement concepts from current AI literature and apply them in a working system

Expected Base Pay Range (USD)

37 - 73, $ per hour.

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.

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.
