Responsibilities
Collaborate with product and design teams to identify high-impact use cases for AI agents. Define agent capabilities, goals, and success criteria based on user needs
Design, build, and maintain the APIs and functions that agents use to interact with the world. This includes integrating with ByteDance internal services, APIs, and creating GSO customized tools from scratch
Develop the core logic that allows agents to reason and create effective plans. You will implement and refine orchestration patterns, whether using ByteDance internal AI frameworks or by building custom agent runtimes
Implement robust guardrails and safety mechanisms to ensure agents operate predictably and securely. This includes error handling, retry logic, and preventing unintended actions
Create comprehensive evaluation frameworks and automated testing suites to measure agent performance. You will define and track key metrics to drive continuous improvement
Implement and optimize memory systems that allow agents to learn from past interactions. You will build and fine-tune RAG pipelines to provide agents with relevant, up-to-date context from knowledge bases
Analyze and optimize the latency, token usage, and computational cost of agent operations. You will balance performance with accuracy to ensure a scalable and cost-effective system
Instrument agents with detailed logging, metrics, and tracing to provide deep visibility into their reasoning processes and actions. You will build dashboards and alerts to monitor agent health and performance
Clearly articulate complex technical concepts to both technical and non-technical stakeholders. You will work closely with your team to share knowledge, review code, and contribute to our engineering culture
