Senior Machine Learning Engineering (GenAI), Trust

Airbnb was born in 2007 when two hosts welcomed three guests to their San Francisco home, and has since grown to over 5 million hosts who have welcomed over 2 billion guest arrivals in almost every country across the globe. Every day, hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way.

The Community You Will Join:

The AI / ML community at Airbnb consists of people who are excited about new technologies, eager to simplify complex systems, and who like to be hands-on developers. They are driven by impact and are interested in building working solutions. They don't shy away from the constraints imposed by the business.

The Difference You Will Make:

Everyone at Airbnb thinks about trust, but our team obsesses over it daily. At the core of trust is safety, and thus we spend a significant amount of our time and energy keeping the community safe. The Trust team is responsible for protecting our community and platform from fraud while also ensuring our hosts, guests, homes, and experiences meet our high standards. We constantly work to fight against online fraud (such as monetary loss, compromised accounts, spam and scam in messages, fake inventory, etc.) as well as offline fraud (theft, property damage, personal safety, etc.). We also work on onboarding and screening of users, and think about complex topics like identity and reputation to ensure that every interaction with Airbnb helps build trust in us and our community. Trust Engineering is responsible for the technology vision and development of a complex stack that runs on every key interaction on the platform.

A Typical Day: 

• Work with the operations team to understand new / emerging fraud vectors that are slipping through our defenses.
• Write data pipelines to generate labels using an LLM based virtual judge.
• Fine tune models to improve accuracy.
• Debug failure cases for existing models.
• Build LFM based workflows for automation.
• Collaborate with cross-functional partners including software engineers, product managers, operations and data scientists to identify opportunities for business impact, and analyze and quantify potential impact.
  

Your Expertise:

• 5+ years of industry experience in applied Machine Learning. An advanced degree such as an MS or  PhD in relevant fields is a plus.
• Strong programming (Python / Java or equivalent) and data engineering  (SQL / Spark) skills.
• Deep understanding of Machine Learning best practices (e.g. training/serving skew minimization, A/B test, feature engineering, feature/model selection), algorithms and architectures (e.g. gradient boosted trees, neural networks/deep learning, optimization), domains (e.g. natural language processing, computer vision, personalization and recommendation, anomaly detection), and modern tools (LLMs, LVMs).
• Experience with building and fine tuning models using Tensorflow, PyTorch, or Jax.
• Industry experience building end-to-end Machine Learning pipelines.
• Exposure to architectural patterns of large, high-scale software applications (e.g., well-designed APIs, high volume data pipelines, efficient algorithms, models).
• Experience with the Trust and Risk domain is a plus.
