Software Architect
About the Role
You will lead the technical architecture for data-intensive DeFi systems, designing scalable backend and data solutions that integrate blockchain and LLM features. You will design data models, build real-time and batch data pipelines, and architect vector database solutions for RAG. You will define integration patterns between smart contracts and backend services, ensure secure transaction processing, optimize performance and reliability, produce architecture documentation and runbooks, and collaborate with AI and engineering teams to operationalize LLM inference and data strategies.
