Overview

We are seeking a highly skilled Senior Backend Engineer to join our team and power our autonomous AI platform. This individual will be responsible for architecting and implementing core services that interface with LangGraph-based workflows, manage data access from structured and unstructured sources, and support seamless orchestration between our AI layers and data infrastructure.

They will also be familiar with LangGraph, LangChain, or equivalent AI orchestration frameworks, and have a solid understanding of vector databases and semantic search.

  • Integrate structured and unstructured data access layers with LangGraph and LangSmith agents.
  • Architect retrieval pipelines using vector databases to enable semantic search for AI agents.
  • Coordinate with data engineers to support RAG workflows across a shared data lake.
  • Develop and maintain task routing, memory management, and agent orchestration logic.
  • Contribute to platform-level observability, metrics, logging, and diagnostics for agentic tasks.
Requirements
  • 4+ years of backend development experience, with strong programming skills (Python, Node.js).
  • Deep experience with serverless architectures, microservices, and AWS (Lambda, EC2, RDS).
  • Familiarity with LangGraph, LangChain, or equivalent AI orchestration frameworks.
  • Working knowledge of vector databases (Chroma, Pinecone) and semantic search.
  • Solid database and API design expertise, particularly with PostgreSQL.
  • Experience building scalable, low-latency backend systems for AI or data platforms.
Preferred Qualifications
  • Experience with agentic AI systems or orchestration of multi-agent workflows.
  • Understanding of RAG patterns in production.
  • Comfortable with Databricks and Unity Catalog data integration strategies.
  • Exposure to AWS Bedrock and large model orchestration in cloud-native environments.
