What you will do
You will lead a team of experienced Data Scientists while remaining deeply involved in the technical work.
This is a hands-on leadership role (~70% hands-on) combining direct modeling work with ownership of team direction and execution.
You will work on core systems that operate at a massive scale, where:
Data is abundant, but labels are scarce and expensive
problems are long-tail and ambiguous
Systems must meet strict latency and cost constraints (pre-bid)
Your responsibilities include:
Lead development of content classification systems across social platforms (Meta, TikTok, YouTube), web, and apps
Design and build models across computer vision, NLP, and multimodal pipelines
Own the full lifecycle: data selection -> labeling strategy -> training -> evaluation -> deployment
Develop strategies for efficient data curation and labeling (active learning, auto-labeling, sampling under scale)
Improve model quality (precision/recall) while balancing cost, latency, and scale
Drive automation systems (auto-labeling, auto-curation, retraining loops)
Apply modern AI approaches (LLMs, embeddings, foundation models) to real production problems
Lead and mentor a team of senior Data Scientists, setting technical direction and pushing execution forward
Work closely with ML Engineering, Product, and Policy to translate ambiguous requirements into scalable systems
Who you are
3+ years of experience leading Data Science / ML teams
6+ years of hands-on experience in Machine Learning / Deep Learning
Strong background in Computer Vision and/or NLP
Experience building and deploying production ML systems at scale
Strong understanding of real-world trade-offs (accuracy, cost, latency)
Technical requirements
Hands-on experience with deep learning frameworks (PyTorch / TensorFlow)
Experience with ML/DS tools (scikit-learn, OpenCV, HuggingFace, etc.)
Experience working with large datasets and model evaluation pipelines
Advantages
Experience with multimodal systems (vision + text + audio)
Experience with LLMs / embeddings / foundation models
Experience with AutoML, active learning, or data-centric AI
