The Role

We are looking for a Marketing Data Scientist Intern to join our team in a hybrid capacity in San Jose, CA, reporting to the Director, Marketing Science and AI/ML within Global Marketing.

Hiring a Marketing Data Science Intern allows us to transform underutilized datasets into actionable growth strategies, such as predictive lead scoring and automated performance dashboards. This role offers a high-ROI opportunity to optimize our advertising spend and improve customer retention through advanced analytics at a minimal cost. Ultimately, it bridges the gap between raw marketing metrics and high-level strategic decisions, ensuring our department remains competitive in an increasingly data-driven market.

What you’ll do (Role Expectations)

  • Develop predictive lead scoring models to rank prospects based on their likelihood to convert, allowing the sales team to prioritize high-value targets and increase overall win rates
  • Analyze behavioral and demographic data to identify distinct customer clusters, enabling highly personalized marketing campaigns that drive higher engagement and $CLV$
  • Quantify the impact of various marketing channels on revenue through Marketing Mix Modeling (MMM) to optimize budget allocation and reduce wasted ad spend
  • Design and analyze rigorous A/B tests for email subjects, landing pages, or ad copy to ensure creative decisions are backed by statistical significance
  • Build and maintain automated data pipelines that transform raw API data into real-time visualizations and automated insights dashboards

Who You Are (Success Profile)

  • You are a problem-solver. You seek out challenges because you are energized by finding solutions, knowing that solving the hard problems delivers the biggest impact.
  • You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. You adapt to what’s needed, navigating seamlessly between high-level strategy and hands-on execution.
  • You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback—knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.
  • You are a learner. You have a true growth mindset and never stop developing yourself, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.
  • You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.

What We’re Looking for (Minimum Qualifications)

  • Actively pursuing a Bachelor’s or Master’s degree in a quantitative field such as Data Science, Statistics, Computer Science, Economics, or Business Analytics
  • Demonstrated analytical thinking and problem-solving skills with the ability to communicate technical findings to non-technical stakeholders
  • Proven status as a motivated self-starter with a clear passion for innovation and technology

What Will Make You Stand Out (Preferred Qualifications)

  • Prior experience in a marketing internship with a technical lens
  • Proficiency in technical tools such as SQL or Python for data manipulation and analysis

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
