Overview
We are looking for a Senior AI / Backend Engineer to design and build production-grade AI systems focused on Intelligent Document Processing (IDP), OCR, RAG, LLM applications, and AI-powered automation.
You will be responsible for taking AI capabilities beyond experimentation and into reliable production systems. This includes designing document ingestion and extraction pipelines, developing RAG architectures, integrating LLMs, building AI agents, and creating APIs that connect AI services with business applications.
You will work closely with product and software engineering teams to turn complex AI requirements into scalable, secure, and measurable solutions.

esponsibilities
- Design and develop production-grade AI/ML and backend systems using Python and FastAPI/Django.
- Build OCR and Intelligent Document Processing pipelines for extracting structured information from documents.
- Design document ingestion, preprocessing, parsing, chunking, embedding, retrieval, and validation workflows.
- Build and optimize RAG pipelines using vector databases and semantic search.
- Integrate and work with LLMs such as OpenAI, Claude, Llama and other foundation models.
- Develop and evaluate prompting, structured outputs, tool calling and agentic workflows.
- Design AI systems capable of handling complex and variable document formats.
- Implement document-level and field-level validation to improve extraction accuracy.
- Develop REST APIs and microservices for AI and document-processing services.
- Work with PostgreSQL, Redis and vector databases such as pgvector, ChromaDB or similar technologies.
- Develop asynchronous processing pipelines using tools such as Celery, queues or event-driven architectures.
- Implement AI evaluation frameworks covering accuracy, hallucination, retrieval quality and extraction reliability.
- Explore and implement AI agents and MCP-based integrations where appropriate.
- Deploy AI services using Docker and cloud platforms such as AWS or Azure.
- Collaborate with software engineers to integrate AI capabilities into production applications.
- Ensure appropriate security and privacy controls when handling sensitive documents and data.
- Monitor production AI systems and continuously improve performance, accuracy and reliability.
Within the first 6 months, you will have helped establish reliable production AI infrastructure capable of:
Document → OCR → Extraction → Validation → Embeddings → Retrieval → RAG/LLM → Structured Output → Business Application
The focus is not simply on "using AI", but on building accurate, scalable and production-ready AI systems.
