Position Summary:
You will build the data curriculum—what data our models learn from, in what mix, and in what order—across pre-training and post-training. This is a senior IC role at the heart of model quality, sitting between the data platform and the research teams, and one of our highest-leverage bets.
Core Responsibilities:
•
Curriculum Ownership: Build the data curriculum—sourcing, mixing, weighting, sequencing, converting—across pre- and post-training.
•
Data-Centric Experiments: Run experiments that quantify how curriculum choices move model quality.
•
Tooling: Build tooling that makes curriculum changes fast, measurable, and reproducible.
•
Understanding Data: Develop an evidence-based understanding of which data helps, which hurts, and why.
•
Cross-Team Influence: Partner across research and data teams and mentor on data-centric methodology.
Required Qualifications:
•
Data-Centric ML: A track record of improving models through data rather than architecture alone.
•
Experimental Rigor: Rigor in experimental design and in correctly attributing model changes to data changes.
•
Influence: The ability to lead a cross-cutting work stream and influence multiple teams without owning them.
•
Engineering: Sound skills to build the tooling your experiments depend on.
•
Communication: Clear communication of results and their implications.
Preferred Qualifications:
•
Experience with large multimodal or VLA training data.
•
Familiarity with data-mixture and scaling-law research.
•
A history of data-centric wins on real models.
