Regeneron is founded on the belief that the right idea, combined with the right team, can lead to significant transformations. Our growing global network is dedicated to inventing, developing, and commercializing medicines that change lives for those with serious diseases. In doing so, we are pioneering innovative approaches to science, manufacturing, and commercialization, as well as redefining our understanding of health.
We are seeking a Senior AI Engineer with deep AI expertise to join our AI & ML Engineering team. This role spans the full development stack — from designing intuitive, responsive front-end experiences to building robust, scalable backend services and data pipelines that power enterprise AI solutions. You will work on advanced projects involving LLM integration, RAG-based architectures, and cloud-native deployments, delivering end-to-end AI-driven products that are performant, reliable, and production-ready.
A typical day might include the following:
Build responsive, modern web interfaces using Next.js and React.js, including server-side rendering, static generation, and micro front-end architecture. Translate AI-driven data and insights into intuitive user experiences and interactive dashboards.
Design, develop, and maintain microservices using Python and Fast API for AI and ML workflows, ensuring scalability, security, and enterprise-grade reliability.
Integrate LLM capabilities (OpenAI, Anthropic, Google) directly into full-stack features, enabling conversational interfaces, intelligent search, and AI-assisted workflows.
Build and optimize data ingestion pipelines for structured and unstructured data sources to power AI models and analytics.
Create secure, high-performance RESTful APIs that bridge front-end experiences with backend AI/ML services and internal LLM access layers.
Implement Retrieval-Augmented Generation workflows and manage vector databases (Milvus) to power intelligent, context-aware applications.
Deploy and manage full-stack services in AWS EKS Kubernetes clusters, ensuring scalability, resilience, and uptime.
