Founding ML Scientist
Associate scientist job in San Jose, CA
Stage: Seed
Team Size: < 10
We're looking for an Applied RS who can run the gamut of ML from infra to modeling and own the entire ML pipeline--taking advanced models into production. Our ideal candidate will be looking to build a co-pilot product from the ground up: helping to drive everything from key architectural decisions, applying SOTA methods, and shipping advanced production models in close collaboration with the founders. In key role, you will have real product ownership and the chance to influence not just what gets built, but how it gets built in a true 0->1 scenario.
If you have 5+ years of experience in Machine Learning (infra and modeling) with 1+ years post-training LLM's and are thinking about starting your own company someday, this could be a great entry-way for you. Not only would you get real-world experience with something so early, but you'd get a chance to make a name for yourself with our investment team as well (making it much easier to get a chance to pitch us on your own idea in the future).

Lead research on data-centric approaches for LLMs, including pretraining corpus design, data valuation, and speculative decoding strategies.
Develop pipelines to process challenging data sources into structured and reproducible training datasets.
Build and optimize agentic data pipelines, integrating retrieval, self-curation, and multi-agent feedback for high-quality training and evaluation data.
Collaborate with researchers on alignment and reasoning-focused training that leverage data-driven approaches for improving LLM capabilities.
Prototype and deploy evaluation frameworks to measure data quality, coverage, and downstream impact on LLM reasoning.
Publish findings at top-tier venues (e.g., NeurIPS, ICLR, ACL, EMNLP) and represent the institute at international conferences.
Contribute to open-source tools, datasets, and benchmarks that advance the global foundation model research community.
Requirements:
Master's degree in Computer Science, Data Science, or a related technical field (PhD strongly preferred)
Experience collecting and curating high-quality text data including multi-lingual data.
Hands-on experience with large-scale dataset curation and preprocessing for ML/LLM training.
Prior works synthesizing complex datasets. Code, math, and agentic data are higher priority
Experience with ML infrastructure for scalable training, evaluation, and debugging.
Experience at the intersection of data and post-training (RL/SFT)
Proven ability to independently drive research questions related to data quality, scaling, or reasoning.
Preferred Experience:
Experience with retrieval-augmented generation (RAG), agentic data pipelines, or reasoning benchmarks.
Contributions to speculative decoding, self-curation, or reinforcement learning from synthetic data.
Background in knowledge graphs, semantic search, or indexing systems.
Strong publication record in leading AI conferences.
Prior contributions to open-source ML data tools or benchmarks.
Prior work on speculative decoding/contributions to LLM serving engines
Prior work on training LLM-as-a-judge
