PhD AI/ML Engineering Intern - NLP, LLM

LinkedIn was built to help professionals achieve more in their careers, and everyday millions of people use our products to make connections, discover opportunities, and gain insights. Our global reach means we get to make a direct impact on the world's workforce in ways no other company can. We're much more than a digital resume - we transform lives through innovative products and technology. We are looking for Artificial Intelligence interns to work on our massive semi-structured text, graph and user activity data sets. This internship will focus on various NLP or LLM concepts to help LinkedIn to become a more intuitive product. LinkedIn's Machine Learning Engineers are both data/research scientists and software engineers, who develop and implement machine learning models and algorithms. Unlike other companies that separate these roles, our engineers work on projects from ideation to implementation. This is a unique opportunity to apply your research expertise to real-world problems, collaborate with industry-leading AI/ML engineers, and build solutions that impact millions of users. Candidates must be currently enrolled in a PhD program, with an expected graduation date of December 2025 or later. At LinkedIn, we trust each other to do our best work where it works best for us and our teams. This role offers a hybrid work option, meaning you can both work from home and commute to a LinkedIn office, depending on what's best for you and when it is important for your team to be together. Our internship roles will be based in Mountain View, CA; or other US office locations. Our internships are 12 weeks in length and will have the option of two intern sessions: • May 27th, 2025 - August 15th, 2025 • June 16th, 2025 - September 5th, 2025 Responsibilities: • Work with large data sets, crunching millions of samples for statistical modeling, data mining, recommendation solutions • Research and develop innovative NLP models, with a focus on LLMs, to solve problems related to information retrieval, text classification, machine translation, and question answering. • Design and implement scalable, production-level algorithms for natural language understanding and generation. • Collaborate with cross-functional teams to integrate NLP/LLM solutions into LinkedIn's platform, enhancing user experience and recommendation systems. • Design Implement, train, and fine-tune LLM and GPT-like models on large-scale datasets to ensure optimal performance and accuracy • Select appropriate annotated datasets for Supervised Learning methods • Use effective text representations to transform natural language into useful features Basic Qualifications: • Currently pursuing a PhD in computer science, statistics, mathematics, electrical engineering, machine learning, or related technical field and returning to the program after the completion of the internship • Knowledge of core computer science concepts such as object-oriented design, algorithm design, data structures, problem-solving, and complexity analysis • Research experience in NLP, LLMs, or related areas. • Experience in Python and popular deep learning frameworks such as TensorFlow, PyTorch, or JAX. • Experience working with transformer models (e.g., BERT, GPT, T5) and understanding of attention mechanisms, transfer learning, and fine-tuning LLMs. Preferred Qualifications: • Experience with large-scale pretraining and fine-tuning of LLMs on diverse NLP tasks. • Hands-on experience deploying NLP models in production environments. • Experience with reinforcement learning, self-supervised learning, and few-shot learning in NLP applications • Practical knowledge with deep learning and machine learning algorithms and the use of popular AI/ML frameworks • Published work in academic conferences or industry circles • Involvement in consumer-facing product development and design • Experience with command of algorithms and data structures • Understanding of text representation techniques (such as n-grams, bag of words, sentiment analysis etc), statistics and classification algorithms • Expertise in clustering, collaborative filtering, and classification techniques (Naí¯ve Bayes, SVM, NN, Boosting Methods, etc.) • Excellent communication skills Suggested Skills: • Machine Learning and Deep Learning • Advanced Data Mining • Strategic thinking and problem-solving capabilities LinkedIn is committed to fair and equitable compensation practices.
