• Collaborate with Product, Engineering, Data, Infrastructure and business stakeholders across Vietnam and Australia to clarify problems and deliver practical solutions
• Document technical decisions, methodologies and findings, and share knowledge through team demonstrations and collaboration forums

• Strong software engineering fundamentals and practical experience building modern applications, backend services or APIs
• Hands-on experience applying LLMs and Generative AI technologies to product or business problems
• Practical understanding of agentic patterns, prompt and context engineering, tool calling, memory and model integration
• End-to-end understanding of RAG, including chunking, embedding models, retrieval approaches, evaluation metrics and vector databases
• Ability to write clean, maintainable and well-tested code and contribute to code reviews, CI/CD and production support
• Awareness of AI safety, explainability, bias, security and reliability considerations in production environments
• Strong problem-solving skills, curiosity and the ability to work proactively through ambiguity with guidance from senior engineers
• Clear written and verbal English and the ability to collaborate effectively with technical and non-technical stakeholders across locations

Preferred Experience:

• 2–5 years of software engineering, machine learning engineering or applied AI experience
• Experience building AI-powered applications, agentic workflows, customer-facing features or internal productivity tools
• Practical experience with RAG or GraphRAG, prompt engineering, LLM evaluation or model optimisation
• Experience integrating AI models with APIs, business systems and production application workflows
• Experience deploying applications or models on AWS, GCP or Azure using Docker
• Familiarity with MLOps or LLMOps tools and practices, including observability, evaluation and automated delivery
• Full-stack software development experience, or experience with computer vision, OCR or time-series use cases
• Experience working in Scrum, Kanban or hybrid delivery environments
