In this role, you will work closely with our CTO and engineering leads to shape key technical decisions around AI architecture, LLM orchestration, model evaluation, and backend scalability. You will serve as a core technical anchor, developing reliable frameworks and internal services that enable product squads to safely, efficiently, and rapidly deliver LLM-powered features. This role is ideal for an engineer who thrives on owning complex system challenges, enjoys optimizing production services, and wants to make a substantial technical impact in applied AI engineering.\nKey Responsibilities\nArchitect & Scale AI Infrastructure: Design, implement, and maintain robust Python/FastAPI microservices and backend systems that integrate LLMs and generative AI capabilities directly into live workflows.\nModel Evaluation & Quality Frameworks: Build automated pipelines and tooling to continuously measure, evaluate, and improve LLM output accuracy, consistency, latency, and safety.\nDeveloper Tooling & Frameworks: Develop internal libraries, abstractions, and standardized patterns that empower engineering squads to ship AI features quickly and reliably.\nProduction Performance & Cost Optimization: Optimize AI services and inference pipelines for throughput, latency, token economics, caching, and high availability.\nArchitectural Leadership: Partner with the CTO and technical leads to evaluate emerging AI technologies, architect retrieval-augmented generation (RAG) pipelines, and design vector search infrastructure.\nEngineering Best Practices: Provide technical mentorship, conduct thorough code reviews, and establish rigorous standards for testing, deployment, and operational observability of AI systems.\nRequired Skills & Qualifications\n5+ years of professional software engineering experience, with a solid background in backend systems, distributed architectures, and API design.\nAdvanced Python expertise: Deep understanding of asynchronous programming (asyncio), performance profiling, clean code architecture, and modern backend development.\nProduction AI/LLM Integration: Proven hands-on experience integrating LLM APIs (OpenAI, Anthropic, open-source models) or generative AI capabilities into live production environments.\nSystem Evaluation & Monitoring: Practical experience measuring, evaluating, and improving AI model output quality, latency, and reliability in real-world applications.\nSystems Design & Problem-Solving: Ability to architect decoupled, scalable services with clear boundaries and maintainable data flows.\nCommunication & Team Collaboration: Strong communication skills (both English and Vietnamese) and the ability to articulate architectural decisions clearly across engineering teams.\nStrong understanding of information security and technology governance, with experience ensuring engineering practices follow company security policies and ISO 27001-aligned procedures.\nNice to Have: Experience with FastAPI, RAG, vector databases (Pinecone, Qdrant, Milvus), LLM observability tools (Langfuse, LangSmith), and MLOps/LLMOps infrastructure.\nWhat We Offer\nOpportunities to work on challenging international software engineering projects.\nOwnership of meaningful technical deliverables and complex engineering challenges.\nA collaborative environment that values engineering excellence, accountability, and knowledge sharing.\nOpportunities to mentor other engineers and contribute to technical best practices.\nContinuous learning and professional development opportunities.\nLong-term career growth within a technology-focused organization.","description_format":"text","description_chars":3873,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"All
