Senior Backend & AI Engineer (Python)

Quick Facts

• Role: Senior Backend & AI Engineer (Python)

Description

Own and build scalable back-end services and APIs in Python, along with AI agents and stateful LLM conversational flows. Design microservices architecture, implement pipelines to store and serve real-time session histories and analytics, and optimize latency for streaming and database queries. As the product scales, help establish engineering best practices, code quality standards, and technical documentation.

Responsibilities

• Design and implement scalable, secure, and efficient back-end services in Python
• Architect and develop advanced AI agents and stateful LLM conversational flows, managing short-term session context and long-term memory extraction
• Build logic to evaluate user interactions and implement structured data pipelines to save, transcribe, and serve real-time session histories and system analytics
• Own technical decisions for backend architecture, APIs, and microservices design
• Explore and evaluate new tools, frameworks, and infrastructure to improve the product and engineering stack
• Collaborate with product managers, designers, and front-end engineers to deliver impactful features
• Proactively identify tech issues, lead research, and resolve complex architectural bottlenecks
• Help establish engineering best practices, code quality standards, and technical documentation as the team scales

Requirements

• 5+ years of back-end development with Python
• Proven hands-on experience building AI agents and orchestrating complex LLM workflows
• Experience deploying RAG pipelines
• Experience with AI orchestration and memory management frameworks (e.g., LangGraph, LangMem)
• Experience with vector search engines such as Qdrant
• Experience with latency optimization for LLM streaming and database queries
• Strong ownership with the ability to do independent research and resolve issues autonomously
• Strong knowledge of PostgreSQL and experience with Object-Relational Mappers (ORMs)
• Experience in early-stage startups or building systems from scratch
• Proactive and highly autonomous, yet disciplined; values structured engineering processes and organized workflows
• Result-oriented, hardworking, and ambitious
