Job Description

Microsoft Research (MSR) is a multidisciplinary global organization creating scientific knowledge and delivering innovation for positive human impact at scale. We work with scientific, engineering, academic, and business partners to apply machine learning and Artificial Intelligence (AI) to advance economics, health, and society. The Microsoft Research Americas Engineering team is hiring a Principal Research Software Engineer to provide technical leadership and direct technical contribution as an individual contributor on the AI Agentic Core Team. Our mission is to accelerate the path from research to product by building AI-driven systems, workflows, and platforms that help researchers and product teams move faster from exploration to real-world impact. In this role, you will collaborate with engineers, researchers, and product teams to build high-impact systems spanning early-stage prototypes through production-ready tools, services, and experiences, while modernizing how we design, build, evaluate, and ship software across Microsoft Research Americas and beyond. This role is well suited for engineers who enjoy moving across layers—from product experiences and services to data, cloud infrastructure, and AI-enabled workflows—and who are energized by applying AI to real engineering and product problems. Deep expertise in how models work is valuable but not required to be effective in this role.

Job Responsibility

  • Design, develop, and ship systems that transition MSR concepts into production-quality tools, services, and product capabilities
  • Build robust solutions spanning product experiences, APIs, data pipelines, model integration layers, and cloud infrastructure
  • Partner with MSR researchers and Microsoft product teams
  • Provide technical direction, mentor engineers, and guide architecture and design decisions
  • Help shape the team's engineering culture, long-term strategy, and adoption of modern AI-driven engineering practices
  • Define and implement AI-driven processes that accelerate how research moves into products
  • Design and integrate agentic AI frameworks and LLM-based pipelines into research tools and engineering workflows
  • Develop tool-use and function-calling architectures
  • Apply modern AI engineering practices
  • Contribute to model experimentation and adaptation

Requirements

Bachelor's Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, Python, Rust, C++, C#, C, Java, JavaScript OR equivalent experience.

Nice to have

  • Master's Degree or Ph.D. in Computer Science, Operations Research, Applied Mathematics, or a related field AND 10+ years of technical engineering experience
  • Experience applying Artificial Intelligence (AI) or Machine Learning (ML) to real systems, products, or engineering workflows
  • Familiarity with agentic AI frameworks, tool use and function calling, prompt engineering, retrieval-augmented generation, evaluation frameworks, model fine-tuning or post-training, observability, and AI-assisted code generation
  • Demonstrated engineering fundamentals and broad technical range
  • Experience providing technical leadership across cross-functional efforts
  • Proficiency with a major cloud and AI platform stack
  • Contributions to research papers, patents, or open-source projects
