Agentic Systems Designer

At eBay, we're building intelligent systems that empower people-not replace them. Our agentic AI team partners closely with product, engineering, UX, research, and responsible AI to design autonomous and semi-autonomous experiences that help buyers and sellers achieve more with confidence.

As an Agentic Systems Designer, you will shape LLM-powered agentic systems that go beyond simple prompt-response behavior to support multi-step task execution, tool use, learning from feedback, and collaboration across multiple agents. Sitting at the intersection of AI systems, human-centered design, and product strategy, you will define how our agents reason, plan, and act in real-world scenarios-ensuring they are transparent, trustworthy, and aligned with human goals.

In this role, you will be a key partner and thought leader for cross-functional teams as we redefine how people buy, sell, and interact on eBay.

What You Will Accomplish

• Design agentic AI workflows that reliably reason, plan, and execute complex end-to-end experiences using tools, memory, and real-world feedback to improve outcomes for buyers and sellers.
• Translate customer and business goals into modular agent architectures, finding the right balance between automation and human-in-the-loop oversight for different risk and complexity levels.
• Define behavioral, interaction, and system-level patterns for agentic experiences, including how agents decompose goals into actionable steps and explain their decisions to customers and internal partners.
• Shape strategies for short- and long-term memory so agents maintain context across sessions, learn from previous interactions, and continuously improve performance and user satisfaction over time.
• Establish and iterate mechanisms for reflection, error detection, and self-correction, using qualitative and quantitative insights to identify workflow breakdowns and increase trust, safety, and reliability.
• Contribute to the design of multi-agent systems (such as supervisor-worker and networked collaboration models), collaborating closely with engineering, product, UX, research, and responsible AI to ship usable, safe, and explainable solutions at scale.

• Experience designing or shaping AI-powered products, agentic workflows, or AI-enabled systems, ideally including exposure to LLM-based or conversational experiences.
• Strong grounding in human-centered design, UX for intelligent systems, or systems thinking, with the ability to reason about both human interaction patterns and the operational complexity of AI services.
• Familiarity with agentic AI concepts such as reasoning loops, tool use, memory management, reflection, and multi-agent collaboration, and an understanding of when and when not to automate.
• Proven ability to collaborate deeply with engineers, product managers, researchers, and responsible AI partners, while advocating for user needs, safety, trust, and transparency.
• Comfort operating in ambiguity, rapidly learning new technical and design patterns, and helping to shape emerging best practices for agentic systems within a dynamic environment.
• Bonus skills such as experience with prototyping tools (for example Figma, Voiceflow, or similar), working with structured configuration formats (such as YAML/JSON), using SQL or Python for interaction/transcript analysis, running A/B tests, or using LLM observability tools to monitor and improve system behavior.
