Role
Who you are
- 5–10 years of industry experience in applied Machine Learning, with a track record of building and productionizing models at scale
- Strong programming skills in Python (required) and familiarity with Scala, Java, or equivalent
- Solid understanding of Machine Learning best practices — e.g., training/serving skew minimization, A/B testing, feature engineering, model selection — and algorithms such as gradient boosted trees, neural networks, transformers, and deep learning
- Experience with ML frameworks and tooling such as TensorFlow, PyTorch, or equivalent
- Experience with data engineering and building end-to-end ML pipelines, including both batch and real-time systems
- Exposure to architectural patterns of large, high-scale software applications (e.g., well-designed APIs, high-volume data pipelines, efficient algorithms)
- Experience with test-driven development, incremental delivery, and deployment practices
- Exposure to the Trust and Risk domain (e.g., fraud detection, anomaly detection, identity, account integrity) is a plus
- A Bachelor's, Master's, or PhD in CS/ML or a related field
What the job involves
- 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 developing the technology that helps protect 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
- You'll work side-by-side with talented product managers, data scientists, software engineers, fraud intelligence, and operations teams
- Together, you'll design and build ML solutions that have direct, meaningful impact on user trust, business success, and the global Airbnb community
- As a Senior Machine Learning Engineer on the Trust team, you will actively contribute code and ideas that shape the ML systems protecting millions of Airbnb users
- You'll own and deliver ML projects end-to-end — from designing and training models to productionizing and operating them at scale — while collaborating closely with cross-functional partners
- You'll tackle real-world challenges such as account takeover, fake accounts, payment fraud, and bot detection
- Your work will help reduce risks posed by bad actors while ensuring the platform remains seamless and welcoming for everyone else
- As you develop your skills, you'll see the tangible impact of your models — helping real users stay safe and confident as they travel, host, and connect on Airbnb
- Collaborate with product managers, data scientists, software engineers, and operations teams to identify opportunities, scope ML solutions, and refine requirements for new or improved Trust models
- Design, build, and productionize end-to-end Machine Learning pipelines — including feature engineering, model training, evaluation, and deployment — for both batch and real-time use cases
- Investigate emerging fraud patterns and threat signals with your teammates, and develop ML-based detections and tools that enable faster, more accurate responses
- Write, review, and ship clean, testable code — whether training a new model, improving an existing pipeline, or optimizing a feature for scalability and reliability
- Work with large-scale structured and unstructured data to continuously improve ML models for Airbnb product, business, and operational use cases
- Participate in code reviews, design discussions, and cross-team collaborations to contribute to a high-quality ML engineering culture
- Work closely with trust defense and platform teams to adapt models and systems to an evolving landscape of fraud attacks
Our take
When Airbnb was originally founded, the product helped customers book air mattresses on people's apartment floors. Since then, Airbnb has had over a billion customers hosted through its platform. With more than 4 million registered hosts worldwide, it has grown into a major player in the hospitality sector.
Airbnb has been successful in disrupting the traditional holiday lettings sector. Before it existed accommodation was limited to hotels and bed and breakfasts, but Airbnb has mainstreamed the idea of renting out spare rooms or even entire homes. It has created a new sector of hosts purchasing properties to rent out on the platform and provides a level of flexibility and a range of offerings not previously possible for travelers.
Perhaps a victim of its own success, by 2022 supply of Airbnb-listed properties began to outstrip demand in some markets, as hosts overestimated the appetite for domestic travel. However, the company is still posting strong financials and has unveiled new tools to support its hosts in a tougher rental market. With a healthy bottom line and a huge user base, Airbnb is very likely to overcome the current market turbulence and continue its growth.
