Role Description

As a Machine Learning Intern, you’ll contribute to advancing Dropbox’s mission to create a more enlightened way of working through cutting-edge research and applied machine learning. You’ll collaborate with experienced engineers and researchers to design, prototype, and evaluate scalable AI/ML systems that power Dropbox Dash’s universal search and intelligent organization features. Your work will shape how millions of people find information, collaborate, and focus on meaningful work.

This internship offers the opportunity to translate your research into real-world impact while gaining experience with large-scale production systems and cross-functional collaboration in a fast-moving, high-impact environment.

Responsibilities

• Research and prototype innovative machine learning approaches in areas such as Search, Large Language Models (LLMs), Multimodal Content Understanding, and Recommender Systems
• Design and implement end-to-end ML pipelines—from data exploration to model training, evaluation, and deployment—in collaboration with mentors and product teams
• Analyze large-scale datasets to identify opportunities for personalization and improved user experiences
• Partner with Product, Design, and Engineering teams to integrate models into Dropbox products
• Contribute to the team’s technical discussions, offering research-based perspectives to guide experimentation and long-term strategy

Requirements

• Currently pursuing a PhD in Computer Science, Machine Learning, Artificial Intelligence, or a closely related field, with a research focus on advanced AI
• Graduation date in Winter 2027 or Spring/Summer 2028.
• Proven experience in applied AI, through research publications, significant projects, or internships where you built or tested advanced ML solutions.
• Strong coding skills (e.g., Python, PyTorch, scikit-learn, or similar ML libraries), plus an ability to quickly prototype and iterate on cutting-edge ideas.
• Curiosity and drive to explore novel ML methodologies and translate them into practical applications that solve user needs.
• Research experience in one or more of the following: Natural Language Processing, Large Language Models, Deep Learning, Recommender Systems, Learning to Rank, Speech Processing, Graph Learning
• Strong analytical and problem-solving skills, with the ability to bridge research and practical application
• Excellent communication and collaboration skills, especially in interdisciplinary teams
• Familiarity with modern ML infrastructure and large-scale data systems

Preferred Qualifications

• Publications in top-tier ML, AI, or NLP conferences (e.g., NeurIPS, ICLR, ICML, ACL, EMNLP, KDD, SIGIR, CVPR)
• Experience with LLM-based applications or Retrieval-Augmented Generation (RAG) systems
• Interest in translating research insights into product impact for real-world users
• Familiarity with the end-to-end process of building AI prototypes: from data exploration and model iteration to evaluation and user testing.
• Passion for swiftly moving from idea to experiment, comfortable with ambiguous or evolving project goals.

Company Description

Dropbox isn’t just a workplace—it’s a living lab for designing a more enlightened way of working. We’re a global community of bold visionaries and resourceful doers shaping the future of Dropbox and, in turn, the future of work. Our Virtual First model combines the autonomy of a distributed workplace with the power of human connection, creating space for meaningful work and lasting relationships. With a startup mindset and enterprise-level opportunities, we expect Dropbox employees to think critically, stay curious, and use modern tools, including AI, to improve how work gets done. Here, you can be who you are and grow into who you’re meant to be. You own your impact, helping make work more intuitive, joyful, and human for yourself and hundreds of millions of people worldwide. If you’re ready to push boundaries and challenge yourself, Dropbox is ready for you.

Team Description

Our Emerging Talent program helps participants grow through mentorship, curated development opportunities, and being a part of a vibrant community. We offer a 12-week summer program where interns can build their technical and non-technical skills, hone their career goals, and connect with peers and leaders at our annual Summit.

Virtual First

Dropbox’s Virtual First way of working is designed to help people do their best work with flexibility, autonomy, and connection. Day to day, teams work remotely with nonlinear schedules and core collaboration hours that support deep focus and individual working styles. We prioritize asynchronous communication to improve clarity, respect deep work time, and reduce unnecessary meetings. While remote work is the primary experience for our employees, we also prioritize intentional, in-person connection. We bring teams together through regular team gatherings, on-demand workspaces, and Dropbox Neighborhood events in order to strengthen team cohesion, foster creativity, and enhance momentum. Virtual First is built to provide the same access to opportunity, growth, and impact for everyone, regardless of location.

This role requires travel to offsites and various other team gatherings (approximately 5-10% of the year or 2-3 days per quarter). We provide advance notice when possible and encourage candidates to discuss any accommodation needs during the interview process.

Dropbox supports responsible use of AI for preparation, but misrepresentation of skills or experience is not permitted. See our AI Principles.

Dropbox is an equal opportunity employer. We are a welcoming place for everyone, and we do our best to make sure all people feel supported and connected at work.
