Project Overview
Our client is a fast-paced startup building ML-powered threat detection systems that identify and neutralize digital disinformation at scale for Fortune 1000 companies and government agencies. Their core platform runs on sophisticated NLP models that process millions of data points in real-time, using advanced classification algorithms and anomaly detection to separate legitimate content from coordinated threats.
As an ML Engineer on this team, you'll architect and implement the machine learning backbone that powers their detection capabilities. You'll work directly with production-grade language models, building everything from content embedding systems to behavioral propensity models that predict threat patterns before they manifest. The technical stack centers on OpenAI's LLMs integrated through LangChain pipelines, with Ray handling distributed model inference and MLflow managing the complete model lifecycle from experimentation to deployment.
Your models will need to operate in resource-constrained environments, requiring expertise in model compression, quantization, and embedded deployment strategies. You'll build supervised classifiers for known threat patterns while simultaneously developing unsupervised clustering algorithms to detect novel attack vectors. The propensity modeling component involves predicting user behavior, content virality, and threat escalation probability across multiple channels.
This isn't just another ML role—you're building the intelligence layer that protects democratic institutions and major brands from sophisticated information warfare. Your algorithms will need to distinguish between genuine grassroots movements and artificial amplification, requiring deep understanding of both technical ML fundamentals and the nuanced behavioral patterns that separate authentic from synthetic content.
The impact is immediate and measurable: your models directly influence real-world security decisions, making this an ideal environment for an ML engineer ready to see their work defend against evolving digital threats while mastering production-scale NLP systems.
