Master's University Grad Machine Learning Engineer 2027

About the Role

Machine Learning Engineers at Pinterest contribute to building personalized experiences to help Pinners create a life they love. This role involves hands-on access to data and contributing to large-scale recommendation systems. You will be considered for multiple roles across various ML teams, with opportunities to work on recommender systems, search, ads, ranking, natural language processing, graph representation learning, and personalization.

Key Responsibilities

• Contribute to cutting-edge research in machine learning and artificial intelligence applicable to Pinterest problems.
• Collect, analyze, and synthesize findings from data to build intelligent, data-driven models.
• Write clean, efficient, and sustainable code.
• Use machine learning, natural language processing, and graph analysis to solve modeling and ranking problems across discovery, ads, and search.
• Design, build, and test models to predict engagement for notifications (push, emails, in-app notifications).
• Build content recommendation systems to power notifications.
• Work on state-of-the-art large-scale applied machine learning projects.
• Scope and independently solve moderately complex problems.

Requirements & Tech Stack

• Master's degree in Computer Science, ML, NLP, Statistics, Information Sciences, or a related field.
• Machine Learning experience in areas such as ranking, computer vision, NLP, content recommendations, embeddings, or information retrieval.
• Experience with big data technologies (e.g., Hadoop/Spark) and scalable real-time systems processing stream data.
• Mastery of at least one systems language (Java, C++, Python) or one ML framework (Tensorflow, Pytorch, MLFlow).
• Proficiency with AI-native engineering, including the design of agent-friendly codebases.
• 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.
• Comfort iterating on prompts, refining workflows, and adapting AI-assisted approaches based on problem, context, and constraints.
• Experience in research and in solving analytical problems.
• Strong communicator and team player. Ability to find solutions for open-ended problems.

Note: This role may require you to be located near a Pinterest office for in-person collaboration.
