About The Position

Snap Inc is a technology company. We believe the camera presents the greatest opportunity to improve the way people live and communicate. Snap contributes to human progress by empowering people to express themselves, live in the moment, learn about the world, and have fun together. The Company’s three core products are Snapchat, a visual messaging app that enhances your relationships with friends, family, and the world; Lens Studio, an augmented reality platform that powers AR across Snapchat and other services; and its AR glasses, Spectacles. Snap Research serves as an innovation engine for the company. Our projects range from solutions to hard technical problems that significantly enhance Snap’s existing products, to riskier explorations that can lead to fundamental paradigm shifts in the way people communicate and express themselves. The team consists of scientists and engineers who experiment with and invent new technology that has a lasting impact on Snap’s products. We also frequently publish our work at top conferences and journals in computer science and related fields. We are looking for a Research Scientist to join our User Modeling and Personalization Research Team! Our team’s mission is to invent new ways to model user behavior, and empower our business partners to build world-class user-centric ML systems which shape personalized experiences across Snap. Our work spans the domains of generative and language models for information retrieval, efficient large-scale recommender systems, and representation learning for structured graph data. Together with you, we seek to redefine the state-of-the-art in technology to deliver our users customized experiences which delight them.

Requirements

• Strong technical knowledge of machine learning, graph modeling (including Graph Neural Networks and Graph Transformers), and state-of-the-art deep learning literature
• Demonstrated ability in defining, leading and executing challenging research projects
• Strong computer science fundamentals, problem-solving and engineering skills (Python, PyTorch)
• Pragmatic, hands-on approach to research with a drive to build working prototypes rather than solely rely on theoretical exploration
• Proven ability to mentor interns, students and junior researchers
• PhD in computer science, machine learning, language technologies or related technical field such as statistics, mathematics, or equivalent years of experience
• Track record of first-author publications in top machine learning or information retrieval venues (e.g. ICLR, NeurIPS, ICML, KDD, RecSys, SIGIR, WSDM, LoG etc.)
• Strong familiarity with PyTorch, and hands-on experience with distributed (multi-node and multi-GPU) machine learning model training, inference and experimentation
• Experience applying graph machine learning models in the context of link-level and node-level tasks

Nice To Haves

• Experience with large-scale graph machine learning problems in an academic or industrial research lab, or equivalent open-source experience
• Experience with large-scale data processing, collection or synthesis using machine learning frameworks on Enterprise Cloud solutions like Google Cloud, AWS, and/or Azure
• Familiarity with machine learning application surfaces in recommendations and safety, and an interest to apply your work at scale
• Familiarity with modern trends in sequence models and language, and their interrelationships with graph modeling
• Demonstrated ability to transform cutting-edge research into tangible product improvements

Responsibilities

• Lead research projects in graph machine learning and relational modeling, with applications to recommendation, classification and safety applications
• Build scalable research prototypes and evaluate them in large-scale machine learning scenarios
• Share your expertise with teammates and interns
• Publish your findings at top conferences
• Partner with engineering teams to deliver your technology to millions of Snapchatters

Benefits

• Snap Inc. is its own community, so we’ve got your back!
• We do our best to make sure you and your loved ones have everything you need to be happy and healthy, on your own terms.
