[Responsibilities] Engineering Leadership & Mentoring Team Growth: Act as a "Player-Coach," mentoring the Vietnam-based team through code reviews, architectural workshops, and career development. Setting Standards: You define the "Gold Standard" for our SDLC—from requirements and testing to production operations and observability. Technical Influence: Lead without always needing direct authority; set the direction for system decomposition, API design, and failure mode reasoning. Production-Grade AI & Agentic Systems Beyond Prototyping: Build and maintain AI-powered features that real users depend on, understand latency implications, cost trade‑offs, and output reliability Agentic Orchestration: Design multi-agent patterns (task decomposition, tool use, memory) using frameworks like LangGraph. AI Evaluation: Establish rigorous AI evaluations to detect regressions and use quantitative signals to improve agent behavior over time. RAG & Knowledge: Implement RAG architectures and embedding strategies to ground AI agents in proprietary knowledge bases. IS Architecture & Strategic Oversight System Urbanization: Act as the architect of a coherent ecosystem, ensure seamless integration across projects, maintaining data integrity, and avoiding technical silos. Project Centralization: Serve as the technical point of contact for the "Fil Rouge" project and emerging projects, ensuring they remain on track and architecturally sound. [Requirements] 3-4 years of experience in a similar role (Tech Lead or Staff Engineer). Strong analytical and problem-solving mindset You are a self-starter who also thrives in a collaborative team environment. Technical requirements: Stack: Proficiency in Python and/or TypeScript/JavaScript across multiple layers of the stack. Architecture: Strong command of system decomposition, scalability, and observability. AI & Workflow Production AI: Real-world experience with LLM API integration, context window management, and fallback strategies. Modern Workflow: Habitual use of AI coding agents (Cursor, Claude, Copilot) as a core part of your engineering process. Evaluation: Ability to define quality metrics and build evaluation datasets for AI features Languages: Vietnamese: full command English: Full professional proficiency. You will lead daily technical and strategic discussions with international stakeholders. French knowledge is a strong plus
