About the Role
We are looking for an AI Engineer to join Hitachi Digital Services Vietnam, part of a global delivery network. This role involves designing, building, and operating AI capabilities that can be safely embedded into real delivery, from LLM-enabled workflows to RAG and agent-based systems.
Key Responsibilities
- βEngineer AI solutions end-to-end: data preparation, model or LLM integration, evaluation, deployment, and operational monitoring.
- βTranslate business and delivery needs into working AI designs, collaborating with architects, platform engineers, and client stakeholders.
- βContribute reusable assets: reference implementations, patterns, templates, internal libraries, and delivery playbooks.
- βBuild with production discipline: testing, version control, CI/CD alignment, and pragmatic performance/scalability considerations.
Requirements
- βStrong software engineering in Python (and/or TypeScript/C#), building API-first services and integrating AI capabilities into real application layers.
- βPractical agent/LLM application engineering: prompt/tool design, orchestration patterns, and integrating with agent frameworks such as LangChain or Semantic Kernel.
- βRetrieval and knowledge patterns: embeddings, vector search, indexing, and using fit-for-purpose stores to support RAG-style systems and memory.
- βMLOps/LLMOps hygiene: reproducibility and lifecycle management, using tools such as MLflow.
- βWorking knowledge of ML/GenAI concepts and common frameworks (e.g., PyTorch, Hugging Face).
- βFamiliarity with cloud platforms (AWS, Azure, or GCP) and the practicalities of deploying AI services into real environments.
- βClear communication and a habit of writing things down (design notes, trade-offs, runbooks).
