Backend Engineer

You will be responsible for building high-performance backend services, integrating advanced AI capabilities using OpenAI/Gemini, and designing robust systems that support real-time, large-scale user interactions. You will work closely with product managers, AI engineers, and frontend/mobile teams to craft APIs, optimize performance, and ensure seamless user experiences across the platform. Responsibilities: - Designing, developing, and maintaining scalable backend services using Node.js. - Integrating OpenAI APIs, embeddings, vector stores, context/memory frameworks, and other LLM-powered features. - Building reliable, secure, and well-documented REST/GraphQL APIs. - Architecting backend systems that support millions of requests with high reliability. - Writing clean, modular, and testable code with strong attention to performance. - Working with cross-functional teams (Product, AI, Mobile/Web) to bring new features to life. - Maintaining database models, optimizing queries, and ensuring high availability. - Implementing monitoring, logging, alerting, and observability for backend services. Requirement: - Bachelors degree in Computer Science, Engineering, or related field. - 3-4 years of professional backend development experience. - Strong proficiency in Node.js, Express/Nest.js, and modern JavaScript/TypeScript. - Hands-on experience with OpenAI APIs, LLM orchestration, prompt engineering, embeddings, and AI memory/context systems. - Experience building scalable, distributed, microservices-based architectures. - Solid understanding of databases (MySQL/MongoDB) and caching systems (Redis). - Familiarity with message queues like Kafka, RabbitMQ, or SQS is a plus. - API security, rate limiting, fault tolerance, and system performance. - Exposure to AI agents, vector databases, or RAG systems is a strong advantage. - Excellent problem-solving skills and a proactive, ownership-driven mindset. - Ability to work collaboratively in a fast-paced, cross-functional team environment.,
