We're seeking a Senior Full Stack Developer who thrives in early-stage product exploration and hands-on AI research and prototyping. In this role, you?ll work on rapid experimentation?translating ideas into working demos using LLMs, orchestration frameworks like LangGraph or CrewAI, and robust Java-based backends with scalable data architectures. You'll collaborate across AI, product, and architecture teams to inform the future platform roadmap. Principal Responsibilities Rapidly prototype AI-driven use cases using Java-based services, frontend components, and integration with AI/ML tools. Build POCs leveraging agentic AI frameworks (LangGraph, AutoGen, CrewAI) and test novel interactions with LLMs and external APIs. Work with SQL/NoSQL databases to model knowledge graphs, embeddings, and AI-generated outputs at scale. Develop intuitive UIs using React or Angular to test agent-based user workflows. Partner with architects and ML engineers to evaluate AI frameworks and identify production candidates. Translate architectural patterns into real-world test cases that help validate platform assumptions. Position Requirements 12+ years of full-stack development experience Deep expertise in Java (Spring Boot, Micronaut, or Quarkus) for building scalable services and APIs.
