Senior Software Engineer (Python) – LLM Agents & RAG Pipelines (3-Month Contract)

Work Type: Contractor | Permanent Remote

Note: This is a contract-based, fully remote opportunity. Payments are made based on actual hours worked. No paid leaves or benefits are included. The contractor must handle their own taxes and compliances.

Job Overview

• We are seeking an experienced Senior Python Engineer to help build and maintain production-grade systems powered by Large Language Models (LLMs). This is a pure software engineering role focused on backend architecture, API design, and intelligent system orchestration — not data science, annotation, or analytics.
• You’ll be developing LLM-integrated systems using modern frameworks like LangChain or LangGraph, helping design scalable backend services that support AI agent functionality and intelligent workflows.

Key Responsibilities

• Design and implement robust backend services and production APIs using Python
• Build and maintain LLM-powered systems, including RAG pipelines, agent workflows, and orchestration layers
• Integrate LLMs (e.g., OpenAI, Anthropic) into scalable services using frameworks like LangChain, LangGraph, or similar
• Collaborate with cross-functional teams to ensure maintainability, observability, and performance in production systems
• Write clean, testable, and well-documented code for long-term scalability

Must-Have Skills

• 5+ years of experience as a backend or full-stack engineer (backend-focused)
• Strong proficiency in Python and API/service architecture
• Hands-on experience integrating LLMs into backend workflows
• Familiarity with LangChain, LangGraph, RAG pipelines, or similar frameworks
• Experience with production deployment, service scaling, and observability tools
• Clear communication skills and ability to thrive in distributed teams
