Data Science Intern

Centerfield • Los Angeles, CA

2d • $30 - $30 • Hybrid

About The Position

Centerfield is looking for a curious, hands-on Data Science Intern to work alongside our Data Science team on the systems that turn millions of customer conversations into intelligence. You’ll contribute directly to our call intelligence and customer data platforms - helping us extract behavioral signals from phone calls, validate predictive models, and activate that intelligence to personalize experiences for over 150 million shoppers annually. This is a builder’s internship: you’ll write real code, work with real data, and ship work that informs real business decisions, all with the mentorship and support of an experienced DS bench.

Requirements

• Currently pursuing a Bachelor’s, Master’s, or PhD in Computer Science, Statistics, Mathematics, Data Science, or a related quantitative field.
• Solid foundation in Python and familiarity with core data libraries (e.g., pandas, NumPy, scikit-learn) through coursework, research, or personal projects.
• Working understanding of machine learning concepts and applied statistics - regression, classification, evaluation metrics, and basic experimental thinking.
• Comfortable querying and manipulating data with SQL, and curious about working with large, messy, real-world datasets.
• Genuine interest in LLMs and Generative AI, with some hands-on exposure (prompting, an API project, a course, or experimentation) even if not yet professional.
• Self-starter who communicates clearly, asks good questions, and is eager to take a problem from notebook to a result the team can use.

Nice To Haves

• Any experience with a major cloud platform, especially GCP (BigQuery, Vertex AI), is a plus.
• Prior work with natural language processing, transcripts, or unstructured text data.
• Familiarity with graph databases (e.g., Neo4j) or customer data/identity resolution concepts.
• Experience building dashboards or visualizations to tell a story with data

Responsibilities

• Analyze call transcripts and help build and refine rules that extract behavioral and intent signals, measuring their accuracy against human-labeled benchmarks.
• Support the team in validating predictive models and traits feeding into our customer data platform - quantifying how well signals correlate with conversion, retention, and customer value.
• Profile and clean high-volume data, surface patterns and quality issues, and translate findings into clear, actionable summaries for the team.
• Get hands-on with modern GenAI workflows -prompting, evaluation, and lightweight RAG experiments - to help assess summary quality and reduce hallucinations in production outputs.
• Build charts, notebooks, and short write-ups that make your analysis easy for both technical and business stakeholders to act on.

Benefits

• Paid charity and volunteer days (local mentor programs, adopt a pet, beach cleanup, etc.).
• Unlimited free snacks and drinks around the office!
• Monthly happy hours, catered Thursday lunches.
• Monthly team outings (ball games, casino night, hikes, etc.).
• Career growth – we enjoy promoting from within!
