Senior AI Backend Engineer - Remotely

The Role Build scalable AI-powered backend systems that form the backbone of our client solutions. You'll architect robust APIs, integrate multiple AI providers with intelligent fallback strategies, and optimize real-time workflows that handle AI processing at scale. What You'll Do ● Integrate and manage multiple AI providers (LLMs, image/video generation) with smart fallback and cost optimization ● Design and optimize prompt engineering strategies for consistent, high-quality AI outputs ● Build high-performance REST/GraphQL APIs using Django and FastAPI with async processing ● Develop real-time features using SSE, WebSockets, and background task processing (Celery) ● Architect scalable microservices with robust error handling, rate limiting, and monitoring ● Optimize database queries, implement caching strategies, and design efficient data models ● Implement RAG pipelines and vector embeddings for context-aware AI responses ● Write comprehensive tests, maintain CI/CD pipelines, and conduct code reviews Requirements:5+ Years of Experience.Python & Frameworks: Django and/or FastAPI in production, async Python (asyncio, async/await) AI Integration: LLM APIs (OpenAI, Gemini, etc.), prompt engineering, token/cost optimization Databases: PostgreSQL (query optimization, indexing), Redis (caching, queuing) Async Processing: Celery or equivalent, message brokers (RabbitMQ, Redis, SQS) DevOps: Docker, Git, cloud platforms (AWS/GCP), CI/CD pipelines API Design: RESTful principles, authentication, rate limiting, error handling.
