Senior Staff Machine Learning Engineer – GenAI

Community you will join

At Airbnb, we’re reimagining how support is delivered at a global scale. The CS Foundations Engineering (CSFE) team is leading a multi-year transformation—building intelligent, AI-augmented systems that provide timely, personalized, and always-on support experiences for our global community.

The CS Foundations Engineering (CSFE) team powers this mission by delivering robust platforms, reusable systems, and developer-facing infrastructure. Our tools help agents deliver exceptional service, enable faster product iteration, and support Airbnb’s mission to create a world where anyone can belong anywhere—with help that’s just a moment away.

The Difference You Will Make:

We’re looking for a Senior Staff ML Engineer/ Scientist to redefine the future of Airbnb’s customer experience through cutting-edge LLM-driven systems that operate at global scale. In this role, you’ll architect and lead the development of AI-first platforms that power millions of real-time support interactions—designing sophisticated LLM orchestration frameworks, retrieval-augmented generation pipelines, evaluation systems, and feedback loops that continuously improve model quality in production. You'll drive the evolution of intelligent Agent Lifecycle Management foundational products. You’ll build agent copilots that reason over multi-modal context, automate complex responses, detect edge cases and outliers, and deliver real-time coaching—while pioneering next-generation AI routing that matches customers to the ideal agent using deep contextual understanding. Thriving at the intersection of ML research, distributed systems, and technical leadership, you’ll partner cross-functionally to turn advances in large language models into reliable, scalable, and measurable product impact—shaping the foundational AI systems that power personalized, differentiated support experiences worldwide.

• Leadership Experience: 10+ years experience leading and guiding machine learning and AI projects that deliver sizable impact as a senior IC.
• Technical Proficiency: Deep knowledge and hands-on experience with Machine Learning best practices (eg. training/serving skew minimization, feature engineering, feature/model selection), algorithms (eg. neural networks/deep learning, optimization) and domains (eg. NLP, computer vision, personalization, search and recommendation, marketplace optimization, anomaly detection)

Preferred Qualifications:

• Agentic and Automation: Experience with AI technologies in automating processes and developing agentic solutions and frameworks.
• Agile Practice for AI Production: Experience with the entire AI product development lifecycle from incubation to production at scale, following agile practices in the Applied AI/ML domain.
• Infrastructure Acumen: Experience building robust testing frameworks for agent behavior validation and continuous improvement, and driving architectural requirements on ML infrastructures
