Member of Technical Staff - AI Data Platform, Frontier Models

** Overview*
* Help build the world's most advanced multimodal dataset at Microsoft AI

We are on a mission to create the largest and most advanced multimodal dataset in the world. This dataset, spanning all modalities from across the web and beyond, will power the training of the world's most capable AI frontier models, pushing the boundaries of scale, performance, and product deployment.

The AI Data Infra team at Microsoft AI is responsible for building data infrastructure to help MAI teams to generate the biggest and best training dataset. Our work involves data pipelines, Spark, Ray, Vector Databases, and all other aspects of data infra.

We are looking for outstanding individuals excited about contributing to the next generation of systems that will transform the field. In particular, we are looking for candidates who:

Are passionate about the role of data in large-scale AI model training

Will thrive in a highly collaborative, fast-paced environment

Have a high degree of expertise and pay close attention to details

Demonstrate a proactive attitude and enthusiasm for exploring new methods and technologies

Effectively manage multiple responsibilities and can adjust to shifting priorities.

Microsoft's mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

Starting January 26, 2026, MAI employees are expected to work from a designated Microsoft office at least four days a week if they live within 50 miles (U.S.) or 25 miles (non-U.S., country-specific) of that location. This expectation is subject to local law and may vary by jurisdiction.

This role is part of Microsoft AI's Superintelligence Team. The MAIST is a  
** startup-like team inside Microsoft AI** , created to push the boundaries of AI toward  
** Humanist Superintelligence-ultra-capable systems that remain controllable, safety-aligned, and anchored to human values.
** Our mission is to create AI that amplifies human potential while ensuring humanity remains firmly in control. We aim to deliver breakthroughs that benefit society-advancing science, education, and global well-being.

We're also fortunate to partner with incredible product teams giving our models the chance to reach billions of users and create immense positive impact. If you're a brilliant, highly-ambitious and low ego individual, you'll fit right in-come and join us as we work on our next generation of models!

** Responsibilities*
* ** Build AI Data Infrastructure and Data Engines*
* Develop and evolve large-scale AI data infrastructure for frontier AI lab. Own data collection, ingestion, cleaning, curation, generation, governance, metadata management, query , analytic and hybrid search , building reusable, observable, and explainable  
** EB-scale data platform
** that support high-quality data for pre-training and post-training workloads.

** Develop Intelligent Multimodal Data Processing Systems*
* Lead automated understanding and processing of text, images, video, documents. Build labeling and taxonomy systems, semantic feature extraction, data quality modeling, and automated data governance capabilities. Design and train models for classification, recognition, captioning, quality scoring, prediction, and related data-processing tasks.

** Build AI-Native Data Pipelines*
* Leverage LLMs, VLMs, and Agents to build intelligent data pipelines that automate data collection, filtering, deduplication, quality diagnosis, annotation/re-labeling, generation, scheduling, orchestration, and anomaly detection. Use AI-native workflows to significantly reduce manual data operations and improve pipeline scalability and efficiency.

** Build AI-Native Data Storage and Table Layers*
* Design open, AI-optimized storage using Lance, Iceberg, Paimon, and Parquet. Support multimodal

data and embeddings, fast random access and scans, schema evolution, transactions, versioning/

time travel, indexing, and interoperable access across training and query engines.

** Discover and Build Rare, High-Value Datasets*
* Develop differentiated datasets for challenging domains, including web/PDF/encyclopedic/private/query-based text data as well as real-world multimodal scenarios such as retail inspection, warehouse inspection, healthcare, education, OCR, GUI interaction, and multimodal trajectories. Apply a combination of  
** real-world data collection, human annotation, and synthetic data generation
** to produce rare and high-value datasets.

** Drive the Data-Model-Evaluation Iteration Loop*
* Use evaluation feedback and model failure analysis to identify data gaps and design targeted datasets and synthetic-data strategies. Establish observable metrics that quantify the contribution of data to model capability improvements, continuously…
