Python Backend Eng(AI)

### Role Summary

We are looking for a strong Python Backend Engineer who will work on building and scaling backend systems that power AI/LLM-driven product features. This role combines solid software engineering fundamentals with exposure to integrating Generative AI capabilities such as RAG, LangChain, and LLM APIs into production-grade applications.

You will collaborate closely with AI/ML specialists and product teams to make intelligent features reliable, scalable, and performant in real-world systems.

### Key Responsibilities

* Design, develop, and maintain high-performance backend services using Python
* Build and maintain RESTful APIs using FastAPI (or similar frameworks)
* Work extensively with SQL and NoSQL databases (PostgreSQL, Redis, MongoDB, etc.)
* Integrate LLM/GenAI capabilities (e.g., OpenAI APIs, RAG, LangChain, LlamaIndex) into backend systems
* Collaborate with AI/ML teams to productionize AI-powered features
* Ensure scalability, reliability, and performance of AI-enabled services
* Write clean, testable, maintainable code following engineering best practices
* Follow Test-Driven Development (TDD) and participate in code reviews
* Work with containerized environments (Docker) and CI/CD pipelines
* Contribute to architectural and design decisions
* Work in a collaborative Agile environment with frontend, DevOps, and product teams

### Required Skills & Qualifications

* 5–7+ years of strong Python backend development experience
* Hands-on experience building REST APIs using FastAPI / Flask / Django
* Strong experience with SQL databases (PostgreSQL/MySQL) and familiarity with NoSQL (Redis/MongoDB/DynamoDB)
* Practical experience integrating LLM / Generative AI features into applications (e.g., OpenAI APIs, RAG, LangChain, LlamaIndex, vector databases, embeddings)
* Solid understanding of software engineering principles, testing (pytest/unittest), and version control (Git)
* Understanding of API security, authentication, and authorization
* Experience with Docker and CI/CD practices
* Familiarity with AWS or other cloud platforms

### What We’re Looking For

A backend engineer who:

* Has strong fundamentals in Python and system design
* Has worked on or experimented with GenAI/LLM integrations
* Is comfortable working at the intersection of backend engineering and AI-powered features
* Enjoys solving performance, scalability, and reliability challenges

### Experience & Education

* Bachelor’s degree in Computer Science, Engineering, or equivalent experience
* 5+ years of professional backend development experience
