**About VinSmart Future**

VinSmart Future is Vingroup’s technology company with the mission of creating a better life through advanced technology and exceptional digital experiences. We are building Vingroup’s unified technology platform, connecting intelligent enterprise operations with customer\-facing digital products and a national\-scale super app. Our teams work across AI, data, cloud infrastructure, identity, finance, HR systems, and next\-generation digital applications.

**The Opportunity**

We are looking for a Senior Full\-stack Developer to join our Data \& AI Platform team and build the core infrastructure powering enterprise AI applications. You will design scalable AI\-native systems involving Multi\-Agent Orchestration, Retrieval\-Augmented Generation (RAG), Model Context Protocol (MCP), and Agent\-to\-Agent (A2A) communication, while collaborating closely with AI/ML engineers and product teams.

**Key Responsibilities**

• Design, develop, and maintain the core features of an enterprise AI Platform with high scalability and reliability.
• Architect end\-to\-end full\-stack systems covering frontend, backend, APIs, databases, microservices, and LLM integrations.
• Build and optimize complete RAG pipelines, including document processing, vector embeddings, semantic search, context retrieval, and prompt engineering.
• Develop sophisticated Multi\-Agent Systems with orchestration logic, task delegation, conflict resolution, state management, and agent collaboration.
• Implement Model Context Protocol (MCP) and Agent\-to\-Agent (A2A) communication frameworks for complex AI workflows.
• Design RESTful APIs and GraphQL services while integrating third\-party AI services and vector databases.
• Optimize performance through profiling, caching strategies, concurrent request handling, and scalable system architecture.
• Maintain high engineering standards by writing unit and integration tests, conducting code reviews, and documenting technical architecture.
• Collaborate with Product Managers, Designers, and AI/ML Engineers while mentoring junior developers.
• Research and evaluate emerging AI technologies, agent frameworks, and prompt optimization techniques to continuously improve the platform.
