We are seeking a skilled Senior Backend Engineer to drive the development of our platform.

  • Developing and maintaining task routing, memory management, and agent orchestration logic.
  • Contributing to platform-level observability, metrics, logging, and diagnostics for agentic tasks.
  • Deploying and managing MCP servers to wrap scraping, proxy, and JS-rendering tooling as standardized Model Context Protocol (MCP) services.
Requirements
  • 4+ years of backend development experience, with strong programming skills.
  • Deep experience with serverless architectures, microservices, and AWS.
  • Familiarity with LangGraph, LangChain, or equivalent AI orchestration frameworks.
  • Working knowledge of vector databases and semantic search.
  • Solid database and API design expertise.
  • Experience building scalable, low-latency backend systems for AI or data platforms.
