Backend Engineer

VinFast is a pioneering electric vehicle (EV) company committed to revolutionizing the automotive industry with sustainable and innovative mobility solutions. As a leading player in the EV market, VinFast is dedicated to delivering high-quality, cutting-edge electric vehicles that redefine the driving experience. Our team consists of passionate professionals driven by a shared vision of creating a greener and more sustainable future through innovation, technology, and excellence.

VINFAST is a pioneering electric vehicle (EV) company committed to building the next generation of intelligent mobility through AI, software-defined vehicles, and cloud-native platforms. The ViTAI (AI OS & Data & Intelligence Platform) team is developing the backend platform that powers VinFast's AI Mobility Assistant (ViTA), AI agents, enterprise AI services, and data products across the VinFast ecosystem.

As a Backend Engineer, you will design and develop the core backend services that enable AI applications at scale. You will build highly available microservices, APIs, agent runtime services, and platform capabilities supporting millions of requests, real-time AI interactions, and secure enterprise integrations. You will work closely with AI Engineers, Data Engineers, Product Managers, and Platform Engineers to deliver production-grade backend systems for both cloud and edge AI.

This role is ideal for engineers who enjoy building scalable distributed systems, solving complex backend challenges, and creating reusable platform capabilities rather than developing isolated business applications.

Backend Platform Development

• Design, develop, and maintain scalable backend services using microservice architecture.
• Build core platform services including API Gateway, Authentication, Authorization, User Management, Tenant Management, and Configuration Services.
• Develop RESTful APIs, gRPC services, WebSocket, and Server-Sent Events (SSE) for real-time communication.
• Design backend services with high availability, scalability, and fault tolerance.

AI Platform Services

• Develop backend services supporting AI Agents, RAG, Prompt Management, Conversation Management, and Tool Calling.
• Build Model Gateway to integrate multiple LLM providers (OpenAI, Azure OpenAI, Gemini, Claude, Qwen, DeepSeek, Ollama, vLLM).
• Develop Agent Runtime services for orchestration, context management, memory, and workflow execution.
• Support streaming AI inference and low-latency AI interactions.

Distributed Systems & Integration

• Design asynchronous architectures using message queues and event-driven patterns.
• Integrate backend services with enterprise systems through REST APIs, gRPC, Kafka, MQTT, and webhooks.
• Develop reliable background processing services using Redis, BullMQ, or equivalent technologies.
• Ensure services are idempotent, resilient, and support retry and recovery mechanisms.

Data & Storage

• Design efficient database schemas for transactional and analytical workloads.
• Optimize PostgreSQL, Redis, and object storage utilization.
• Collaborate with Data Engineering teams to expose backend APIs for AI and analytics platforms.
• Implement caching strategies to improve system performance and reduce infrastructure costs.

DevOps & Cloud Infrastructure

• Deploy backend services on Kubernetes using Docker containers.
• Build and maintain CI/CD pipelines with GitLab CI or GitHub Actions.
• Monitor system health, logging, tracing, and alerting using Prometheus, Grafana, and OpenTelemetry.
• Continuously improve platform reliability, scalability, and operational efficiency.

Security & Governance

• Implement secure authentication and authorization mechanisms (OAuth2, JWT, API Key).
• Ensure compliance with enterprise security standards and secure coding practices.
• Build audit logging, API rate limiting, secret management, and access control mechanisms.
• Collaborate with security teams to maintain secure backend services.
