Master's Machine Learning Internship 2027 (USA)

Join Pinterest as a Machine Learning Intern for a 12-week paid internship. You'll work on cutting-edge research in machine learning and artificial intelligence, gaining hands-on experience with production ML systems. The internship offers two start dates in May or June 2027, with remote or hybrid options in various US locations.

• Lead your own project from start to finish, contributing to cutting-edge research in machine learning and artificial intelligence that can be applied to Pinterest problems.
• Gain hands-on experience with production ML systems, including algorithmic research, infrastructure, data engineering, training, inference, and product.
• Validate AI-generated outputs through testing, code review, and critical thinking, ensuring solutions are accurate, maintainable, secure, and aligned with team standards.

• Proficiency with AI-native engineering, including the design of agent-friendly codebases
• Working towards a Master's degree in Computer Science, ML, NLP, Statistics, Information Sciences or related field
• Mastery of at least one systems language (Java, C++, Python) and one ML framework (Tensorflow, Pytorch, MLFlow)
• Strong communicator and team player. Being able to find solutions for open-ended problems
• High degree of autonomy in learning new agent-first development tools
• Strong critical thinking when working with AI-generated suggestions, with a clear approach to validating correctness, performance, security, and maintainability
• Machine Learning (ranking, computer vision, NLP, content recommendations, embedding, information retrieval etc)
• Comfort iterating on prompts, refining workflows, and adapting AI-assisted approaches based on the problem, context, and constraints
• Experience in research and in solving analytical problems
