. About the Role
OBS Digital Services is building next-generation platforms, including multi-sided marketplaces (food delivery and booking systems) and AI-powered media processing applications. We are seeking a strong Backend & AI Engineer to architect our core infrastructure. Working from our Kanchrapara office, you will design robust APIs, handle complex database schemas, and seamlessly integrate Generative AI capabilities into our products.
2. Key Responsibilities
- API Architecture: Design, build, and maintain high-performance RESTful APIs using Python and FastAPI.
- Database Management: Architect and manage robust database schemas (PostgreSQL/MySQL), ensuring data integrity and handling concurrency to prevent issues like double-booking.
- AI Integration: Build and optimize pipelines connecting to Large Language Models (LLMs like Gemini, Claude, or local models via Ollama) for text generation, semantic extraction, and media processing.
- Background Processing: Manage asynchronous task queues (e.g., Celery, Redis) to handle long-running operations like video processing without bottlenecking the main application.
- DevOps & Security: Implement secure authentication (JWT, RBAC), manage Docker containers, and handle server deployments.
3. Required Skills & Experience
- Backend Mastery: Proven professional experience writing clean, scalable, and type-hinted Python code.
- Frameworks: Deep understanding of FastAPI, Pydantic, and modern async programming in Python.
- System Design: Experience handling complex application states, rate-limiting, and third-party API integrations (e.g., payment gateways, AWS/GCP services).
- AI Pipelines: Hands-on experience working with AI endpoints, prompt engineering, and processing JSON outputs from language models.
