Overview

Join ZoomInfo’s Product department as a Summer Intern to work on high-impact projects that power our go-to-market data products. You’ll join one of the three teams below to participate in real work using AI alongside experienced mentors, with a strong emphasis on data quality, reliability, and learning fast.

What you'll do

Option A: DS and Applied ML AI Team
Build real-world ML systems—recommendations, scoring models, ad optimization, AI agents, and datasets—that power intelligent go-to-market workflows. As an intern, you’ll get end-to-end experience from problem discovery and analysis through model design, experimentation, and deployment on systems that impact millions of users and businesses.

Option B: Customer Products Team
You’ll help build and scale backend services, APIs, and data pipelines (Java/Python) on AWS that power ZoomInfo’s customer-facing data delivery, analytics, and advertising platforms. You’ll also support AdTech campaign features and applied AI initiatives (including LLM-based tooling), working closely with senior engineers in a mentorship-focused environment.

Option C: Meta-Agent Team
Build a reinforcement learning-inspired meta-agent that treats eval pass rates as a reward signal, proposes prompt and tool configuration experiments as actions, and uses an LLM as the policy to reason about why previous experiments failed and what to try next — iterating through the platform's config versioning system to converge toward optimal agent parameters without human intervention.

What you’ll bring

• Undergraduate junior status (or graduating Jan–Aug 2027) in Computer Science.
• Strong programming fundamentals, required to pass a complex coding assessment.
• Clear communication, strong problem-solving, and comfort working in a fast-moving environment.
• Able to commute to Bethesda, MD or Waltham, MA (in office 4 days/week, 1 day WFH).
• Can commit to the program for the full 10 weeks, between June 1 – August 7, 2026.
