We are hiring a Senior Data Scientist focused on the research and productionalization of Large Language Models for multimodal social media content understanding.
Work with multi-terabytes of social media platform data from TikTok, YouTube, Facebook, Instagram, and Snap.
Fine-tune, optimize, and deploy LLMs that understand what hundreds of millions of videos, images, and text posts are about.
Span the full lifecycle — from research and prototyping to production-grade serving at scale.
Build sophisticated compound AI systems that combine multiple models and modalities into reliable, scalable pipelines.

Bachelor's or Master's degree in Computer Science or related field with 4+ years of professional experience in machine learning or data science
Hands-on experience fine-tuning large language models (open-source and/or closed-source)
Experience with LLM inference optimization — KV cache management, quantization, multi-node GPU serving, batching strategies, and serving frameworks (vLLM, TensorRT LLM, SGLang)
Track record of taking ML models from research to production at scale
Fluency with Python and SQL (specifically Snowflake)
Experience working with multimodal models and features
Familiarity with cost/quality tradeoff analysis across LLM providers and self-hosted models
Experience with distributed systems and GPU-accelerated workloads
Strong foundation in data structures, algorithms, and software design
Thorough testing and code review standards/practices
Strong verbal and written communication skills
Experience working with Autonomous Coding Agents
Openness to new technologies and creative solutions
