Senior Machine Learning Scientist Introduction to the Team Expedia Technology teams partner with Product teams to create innovative products, services, and tools, delivering high‑quality experiences for travelers, partners, and employees. A technology platform powered by data and machine learning offers secure, differentiated, and personalized experiences that drive loyalty and traveler satisfaction. The Traveler Discovery & Planning team is at the forefront of AI‑driven agentic systems, dedicated to enhancing customer experiences, increasing engagement, and strengthening traveler relationships through cutting‑edge machine learning solutions. Our work directly impacts millions of travelers worldwide. We focus on Agentic Experiences that revolutionize traveler experiences with autonomous, intelligent agent systems and conversational AI that anticipates needs and provides personalized trip planning. In this role, you will:
Design, build, and evaluate multi‑step agentic AI systems, including autonomous agents capable of planning, tool use, memory management, and multi‑agent collaboration. Research and implement state‑of‑the‑art techniques in agentic architectures, such as ReAct, reflection loops, chain‑of‑thought prompting, and tool‑augmented reasoning. Develop and maintain agent orchestration frameworks, defining how agents decompose tasks, delegate to sub‑agents, and handle failure and recovery. Integrate large language models (LLMs) with external tools, APIs, databases, and code‑execution environments to enable real‑world task completion. Define and own evaluation frameworks for agentic systems, measuring task success, reliability, latency, cost and safety across diverse benchmarks and production scenarios. Collaborate closely with product, engineering, and research teams to translate business requirements into agentic system designs and deliver production‑grade solutions. Identify and mitigate risks specific to agentic systems, including prompt injection, unintended actions, hallucination in long‑horizon tasks and unsafe tool use. Stay current with the rapidly evolving agentic AI landscape, synthesizing academic research and industry developments to inform the team’s technical direction. Mentor junior ML engineers and scientists, providing technical guidance on agentic design patterns, LLM best practices, and experimentation methodology.
Minimum Qualifications
8+ years of related industry experience. Demonstrated experience designing and deploying agentic or multi‑step AI systems (e.g. ReAct, tool‑calling agents, multi‑agent pipelines) in production or research settings. Strong proficiency in Python and ML frameworks (PyTorch, TensorFlow, or JAX); experience with LLM APIs and orchestration libraries such as LangChain, LlamaIndex or similar. Experience integrating LLMs with external tools, APIs and structured data sources for real‑world task completion. Solid understanding of prompt engineering techniques including chain‑of‑thought, few‑shot prompting and structured output generation. Experience defining and running evaluation frameworks for ML systems, including offline benchmarking and production monitoring.
Preferred Qualifications
PhD, MS or BS in Computer Science, Machine Learning, Statistics, Engineering or a related field; or equivalent professional experience. Experience in the travel or e‑commerce industry. Publications in top‑tier ML conferences or journals. Patented inventions, pending and issued. Contributions to open‑source ML projects. Experience taking models from prototype to production in collaboration with Machine Learning Engineering teams.
