Your Team, Your Impact

Marvell's CTO Office AI Research Group is looking for a motivated advanced BSc student to join our team as a Data Preprocessing Engineer. You will play a foundational role in building the data infrastructure that powers our AI research — working directly with large-scale, real-world datasets at the intersection of machine learning and semiconductor chip design.
This is a hands-on, high-impact student position for someone who enjoys getting into the details of messy data and turning it into clean, structured, and model-ready assets.

What You Can Expect

• Collect, clean, normalize, and sanitize large-scale chip design datasets from diverse sources and formats
• Build and maintain scripts and pipelines to automate repetitive data extraction and transformation tasks
• Parse and process a wide variety of file formats (JSON, CSV, Parquet, logs, and domain-specific EDA formats)
• Navigate complex codebases and directory structures to locate, understand, and extract relevant data
• Work with structured and semi-structured data using SQL and Python-based tooling
• Collaborate with researchers and engineers to understand data requirements and deliver model-ready datasets
• Document data sources, transformation logic, and dataset versions in shared repositories

What We're Looking For

• Advanced BSc student in Computer Science, Software Engineering, Electrical Engineering, Data Science, or a related field
• Good Python skills with hands-on experience using pandas and NumPy for real data manipulation
• Solid SQL and comfort working with structured and semi-structured data (JSON, CSV, Parquet, logs)
• Practical experience cleaning, normalizing, and sanitizing messy, real-world data
• Comfort navigating codebases and filesystems — understanding directory/file structures and parsing multiple file formats
• Git fluency — reading commit history, diffs, and working with versioned repositories
• Scripting ability to automate repetitive extraction and transformation tasks

• Exposure to data pipeline tools or frameworks (e.g., Airflow, dbt, Spark)
• Basic familiarity with ML concepts — understanding what makes a good feature, and awareness of train/test leakage
• Curiosity for reverse-engineering undocumented data and uncovering hidden relationships across files and datasets

This role is eligible to participate in Marvell's bonus and equity plans, including a new hire equity grant and annual equity refreshers, ensuring you are rewarded for your contributions and remain invested in the company's long-term success.
