Our Search & Recommendations team works on delivering recommendations at scale and in near real time to our buyers on our website and native app platforms. Recommendations are a core part of how our buyers navigate eBay’s vast and varied inventory. Our team develops state-of-the-art recommendations systems, including agentic workflows, deep learning based retrieval systems for personalized recommendations, machine learned ranking models, as well as advanced MLOps in a high volume traffic industrial e-commerce setting.
We are building cutting-edge agentic workflows and next-generation recommendation experiences powered by the latest advancements in LLMs, foundation models, and multi-agent orchestration. We are looking for a Machine Learning Engineer who can develop this effort forward bringing complex, autonomous systems into production at eBay scale. In this role, you will bridge the gap between state-of-the-art research and massive production systems. You will work closely with leaders and globally distributed teams across our Search & Recommendations organization, including product, design, and analytics, to design the mechanics of how multiple intelligent agents collaborate, and reason to enable the future of personalized e-commerce shopping.
What you will accomplish:
Design & Architect Multi-Agent Ecosystems: Build and evaluate robust, multi-step agentic systems on a variety of customer-facing surfaces at eBay, focusing on architectures where multiple agents coordinate, delegate, and communicate to solve complex user intents.
Collaborate with World-Class Experts: Work with a team of applied researchers and engineers with deep expertise in natural language processing, large language models / AI / agentic workflows, recommender systems, and ML production engineering
Advance Orchestration Research: Investigate and implement brand new techniques in agent interaction patterns, including structured communication protocols, reflection loops, evaluator-generator frameworks, and tool-augmented reasoning.
Solve Agentic Scale Challenges: Address unique, frontier challenges inherent to multi-agent production systems, including latency optimization for long-horizon tasks, cost management, safety/guardrails, and handling cascading failures.
Drive Marketplace Impact: Work with unique, massive datasets of unstructured, multimodal inventory data to move core marketplace metrics (GMB) through thorough A/B testing of autonomous user experiences.
What you will bring:
MS/PhD in Computer Science or related area.
5+ years relevant work experience in Machine Learning / AI / ML Engineering
Demonstrated experience researching, building, or studying systems where multiple agents interact, exchange information, critique reasoning, and coordinate decisions over time (e.g., ReAct, tool-calling loops, planning systems).
Extensive development experience, preferably in a ML/AI technology environment (Python, PyTorch, etc.)
Experience with using cloud services, big data pipelines and databases in an industrial setting
Experience in Natural Language Processing (NLP) and industrial recommender systems
