This role sits at the intersection of research and engineering and focuses on defining the engineering foundations that enable retrieval research to be translated into reusable, extensible and broadly adopted systems across Microsoft products and experiences. You’ll report to a Distinguished Scientist and Vice President, and work with a world-class team of researchers and engineers.\nWhy MSR India?\nWork at the forefront of machine learning and systems with a team that sets the bar for rigor and impact. Your work will directly influence how retrieval research is translated into reusable engineering systems and scaled across Microsoft products and experiences. You will set the engineering standards, core interfaces, and evaluation framework that govern how new retrieval methods and models are built, validated and adopted across Microsoft. You will also have the opportunity to present the team’s work at the senior most levels of leadership (CEO, CTO, and Board) and shape their thinking in this space.\nApply on the link above. In addition, please ensure to send an e-mail to the MSRI AIML Hiring Committee attaching your CV and sharing details of relevant work experience, highlights of major accomplishments and evidence of software engineering leadership and ML knowledge in the body of your e-mail.\nResponsibilities\nOwn the architecture and long-term evolution of a shared engineering platform for retrieval systems.\nOwn the shared repository and codebase for retrieval methods, driving its architecture, extensibility, engineering quality and long-term health.\nWork with researchers and partner engineering teams to integrate new retrieval methods into a reusable, scalable and well-structured codebase.\nImprove the developer and researcher experience through clear APIs, examples, tooling and workflows.\nDrive integration with downstream systems and partner teams so that retrieval methods can be adopted faster and more reliably.\nProvide cross-team technical leadership, influencing engineering direction and quality standards across collaborating teams.\nQualifications\nRequired Qualifications\nBachelor’s or Masters in Computer Science, Engineering, or related fields.\nStrong software engineering skills with a proven track record of designing, building, reviewing and maintaining high-quality code in large shared codebases.\nSignificant experience owning or building shared platforms, frameworks, repositories or ML systems used by multiple teams.\nStrong communication and cross-team collaboration skills, with the ability to drive alignment .\nHigh ownership, sound judgment, and the ability to independently drive ambiguous technical problems to completion.\nPreferred Qualifications\nProven ability to work with researchers, engineers, and partner teams to turn research ideas into robust engineering systems.\nGood understanding of machine learning systems and retrieval methods, such as dense, sparse, or hybrid retrieval, ranking/reranking, and evaluation metrics.\nExperience building evaluation, benchmarking, or platform infrastructure for machine learning systems.\nFamiliarity with distributed systems, performance optimization, and GPU-backed ML workflows.\nThis position will be open for a minimum of 5 days, with applications accepted on an ongoing basis until the position is filled.\nMicrosoft is an equal opportunity employer.
