Research Internships at Microsoft provide a dynamic environment for research careers with a network of world-class research labs led by globally-recognized scientists and engineers, who pursue innovation in a range of scientific and technical disciplines to help solve complex challenges in diverse fields, including computing, healthcare, economics, and the environment.

The Machine Learning and Optimization (MLO) group in MSR-Redmond performs research in the intersection of optimization, machine learning and systems. Our focus right now is in combining Large Language Model (LLM) technology with optimization for efficient decision making. Example projects include training LLMs for algorithm design (e.g., natural language to integer programming, heuristic design), accelerating optimization algorithms for interactive decision dialogues and using LLMs for sequential and distributed decision-making settings. More broadly, our research leverages theoretical insights for designing algorithms and Machine Learning (ML)-based solutions that run efficiently at scale.

Research Interns put inquiry and theory into practice. Alongside fellow doctoral candidates and some of the world’s best researchers, Research Interns learn, collaborate, and network for life. Research Interns not only advance their own careers, but they also contribute to exciting research and development strides. During the 12-week internship, Research Interns are paired with mentors and expected to collaborate with other Research Interns and researchers, present findings, and contribute to the vibrant life of the community. Research internships are available in all areas of research, and are offered year-round, though they typically begin in the summer.

Additional Responsibilities

Research Interns are expected to design algorithms/models and prototype them, conduct experiments, and analyze results. They are encouraged to show initiative throughout the Research Internship and suggest further directions for research. They are expected to document their ideas, and given suitable results, contribute to a paper.

Required Qualifications

• Currently enrolled in a PhD program in Computer Science, Operations Research or a related STEM field.
• At least 3 years of experience in C# or C++ or Python (or similar language).

Other Requirements

• Research Interns are expected to be physically located in their manager’s Microsoft worksite location for the duration of their internship.
• In addition to the qualifications below, you’ll need to submit a minimum of two reference letters for this position as well as a cover letter and any relevant work or research samples. After you submit your application, a request for letters may be sent to your list of references on your behalf. Note that reference letters cannot be requested until after you have submitted your application, and furthermore, that they might not be automatically requested for all candidates. You may wish to alert your letter writers in advance, so they will be ready to submit your letter.

Preferred Qualifications

• Experience in optimization/algorithm design.
• Experience in machine learning and LLMs (e.g., data curation, post-training, agentic frameworks).
• Demonstrated ability to run simulations and analyze results.
• Some knowledge of distributed systems.

The base pay range for this internship is USD $6,710 - $13,270 per month. There is a different range applicable to specific work locations, within the San Francisco Bay area and New York City metropolitan area, and the base pay range for this role in those locations is USD $8,760 - $14,360 per month.
