  • Skill Design: Developed agent skills including Function Calling, MCP Server integration, and Streaming APIs
  • Design DAG (Directed Acyclic Graph) reasoning flows to break down ambiguous user requests into executable steps
  • Solve critical runtime challenges like "Context Rot" (context overflow) by designing strategies for context offloading, isolation, and intelligent compression
  • RFT: Architect the Automated Data Flywheel system. Design Reward Functions and LLM-as-a-judge pipelines to programmatically evaluate agent performance and drive reinforcement learning

Requirements

  • 3–5 years of backend or AI engineering experience
  • at least 1+ years specifically in LLM application architecture
  • deep practical knowledge of advanced agent patterns (e.g., Plan-Act-Reflection)
  • proven ability to design complex distributed systems
  • experience defining API standards and data protocols for cross-team usage
  • proven experience in building AI agents, with a solid understanding of the ReAct (Reasoning and Acting) mechanism
  • familiarity with the design principles of LLM orchestration frameworks such as LangChain Claude Agent SDK and Manus
  • experience implementing RLHF (Reinforcement Learning from Human Feedback) or DPO concepts to align agent behavior with business goals

What we offer

  • Meaningful Ownership An Employee Stock Ownership Plan (ESOP) that gives a real stake in Plaud’s long-term success
  • High-Impact Environment Work in a fast-moving, product-driven environment where your ideas directly shape the future of AI productivity
