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 AirCase, our unified, platform-native case management system, embedding large language models directly into core workflows via robust APIs while replacing legacy CRM infrastructure with intelligent, adaptive systems. 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.

A Typical Day: 

• Work with large scale structured and unstructured data; explore, experiment, build and continuously improve Machine Learning models and pipelines for Airbnb product, business and operational use cases.
• Work collaboratively with cross-functional partners including product managers, operations and data scientists, to identify opportunities for business impact; understand, refine, and prioritize requirements for machine learning, and drive engineering decisions.
• Hands-on develop, productionize, and operate Machine Learning models and pipelines at scale, including both batch and real-time use cases.
• Leverage third-party and in-house Machine Learning tools & infrastructure to develop reusable, highly differentiating and high-performing Machine Learning systems, enable fast model development, low-latency serving and ease of model quality upkeep.
• Collaborate actively with engineers to apply ML / AI in their solutions to help validate ideas and guide to the right outcomes.
• Partner with other ML Engineers in foundations engineering to mentor and develop initiative to make ML application a core discipline for non ML engineers. 

Minimum Qualifications:

• Educational Background: PhD in Computer Science,  Mathematics, Statistics, or related technical field.
• Industry Experience: 10+ years of experience in building, testing and shipping AI models and products from inception to production; including 2+ years of experience with GenAI. 
• 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
