Machine Learning Engineering Intern (Masters/PhD) - Summer 2027

Machine Learning Engineers at Riot combine expertise in data processing, automation, machine learning, artificial intelligence, and experimentation to develop data-powered products that improve the player experience, protect competitive integrity, and ensure fair play.

As a Machine Learning Engineering Intern, you’ll work with experienced engineers, data scientists, and game or product partners to explore how data and machine learning can support Riot’s games, from shaping engaging player experiences to safeguarding fair and competitive play. You’ll gain exposure to the full ML development cycle, including preparing datasets, engineering features, prototyping models, evaluating results, and communicating findings. You’ll be supported by your team as you learn to build reliable, well-documented solutions.

• Collaborate with machine learning engineers, data scientists, software engineers, and product partners on player- or developer-focused projects.
• Prepare, clean, and explore datasets for machine learning and data-powered applications.
• Implement feature engineering, modeling, and evaluation approaches under the guidance of experienced team members.
• Build prototypes, analyses, visualizations, or internal tools that help teams understand player experiences, product systems, or adversarial behavior.
• Apply testing, documentation, and reproducibility practices to code and experiments.
• Participate in code reviews, technical discussions, team rituals, and project planning.
• Communicate technical findings and tradeoffs to both technical and non-technical collaborators.

• Graduating in the 2028 calendar year with an MS or PhD.
• Currently enrolled in a Computer Science, Machine Learning, Artificial Intelligence, Statistics, Mathematics, Engineering, or related quantitative degree program.
• Available to work full-time hours for the 12-week internship duration.
• Comfortable programming in Python.
• Understanding of machine learning fundamentals, statistics, and data structures and algorithms.
• Experience working with data using tools such as Python libraries, SQL, or notebooks.
• Minimum GPA of 2.5.

• Experience building or evaluating machine learning models through coursework, research, internships, or personal projects.
• Familiarity with one or more machine learning frameworks or libraries, such as PyTorch, TensorFlow, scikit-learn, or Spark MLlib.
• Familiarity with SQL and relational databases.
• Experience with data visualization, experiment design, model evaluation, or statistical analysis.
• Familiarity with software development practices such as Git, unit testing, functional testing, or continuous integration and deployment.
• Experience working with cloud platforms, distributed data systems, or model deployment tools.
• Portfolio, website, GitHub, research publication, or other collection of original work.
• Experience working on a video game or related project, particularly in Unity or Unreal Engine.
• An interest in applying machine learning to either enhancing player experiences or to ensuring competitive integrity through cheat detection.

• Candidates must be legally authorized to work in the United States for the duration of the program.
• This position is not eligible for visa sponsorship. We do not sponsor visas for this position or internship conversions.

For this role, you’ll find success through craft expertise, a collaborative spirit, and decision-making that prioritizes the delight of players.
