Job Description: Role Description: At Booking.com, data drives our decisions. Technology is at our core. And innovation is everywhere. But our company is more than datasets, lines of code or A/B tests. We’re the thrill of the first night in a new place. The excitement of the next morning. The friends you make. The journeys you take. The sights you see. And the food you sample. Through our products, partners, and people, we make it easier for everyone to experience the world. Team and Role Overview Ensuring we understand the needs and intentions of our travelers remains a top priority for Booking. With millions of accommodations, flights, taxis, attractions, and car rentals available on our platform, our aim is to assist customers in finding the perfect fit for their journey. Customers may express their needs and intentions directly through their searches or filter usage, while in addition we can further deduct their preferences from their interactions on our platform, such as clicking on specific… accommodations rather than others. At Booking, we consistently analyze and model customer behavior to personalize the traveler experience. Following successful user intent and needs modeling across various parts of the company, these efforts have recently been consolidated into a central team, and as part of the Traveler Centric Data track within the new Marketplace business unit we are now expanding further. The User Intent Modelling team is building upon past successes, while also deepening on innovation to push the boundaries for personalisation even further by leveraging innovative Machine Learning and Artificial Intelligence. It is a crucial aspect of the Marketplace vision to ensure we guide our travelers to the most suitable products and facilitate seamless connections between the various parts of their trip. As a Senior Machine Learning Scientist, you will be a strong technical leader within the team, setting the technical strategy, while generating operational business impact. You will be developing state-of-the-art Machine Learning models, owning the design and delivery of ML systems, from initial idea-generation, collecting business requirements from product stakeholders to implementation. You will actively coach and mentor less experienced Machine Learning Scientists and Machine Learning Engineers in the team and work closely together with Data Engineers, Software Engineers and Product Managers. Key Job Responsibilities • Translate broad business problems into ML/AI challenges and develop a targeted research plan to identify the best approach within the constraints of the production environment. • Develop the technical strategy for machine learning on a product family by designing innovative ML/AI models, algorithms, and approaches that deliver both short-term commercial impact and longer-term differentiated business value and customer experiences. • Work in a multi-disciplined team where you’ll take full ownership of turning discoveries and ideas into products through machine learning (incl. understanding product requirements, data discovery, model development and evaluation, to implementation of a full production pipeline for both batch and stream-based deployment). • Define and build proof-of-concepts to test new ideas and demonstrate their potential value to relevant stakeholders. • Develop production-grade ML code for models, features, and pipelines, accounting for scalability, latency, realtime requirements, monitoring and retraining. • Build readable and reusable code, using the right technologies and coding methodologies applying knowledge of business area tools and product needs. • Continuously evolve your craft by keeping up to date with the latest developments in ML/AI and related technologies, introducing them to the machine learning community and promoting their application. • Promote platform-based development and reuse by coaching teams in abstracting individual business problems to generalized ML/AI products, rather than point solutions, and in identifying horizontal opportunities across multiple business domains. • Maintain a highly cross-disciplinary perspective, solving issues by applying approaches and methods from across a variety of ML/AI disciplines and related fields. Coach others through evidence and clear communication, explaining advanced technical concepts in simpler terms. • Actively contribute to Machine Learning at Booking.com through training, exploration of new technologies, interviewing, onboarding and mentoring colleagues. Role Qualifications and Required Skills • Strong relevant work and/or academic experience (MSc + 8 years of working experience, or PhD + 6 years), involved in the development and application of Machine Learning. • Masters degree, PhD or equivalent experience in a quantitative field (e.g. Computer Science, Mathematics, Artificial Intelligence, Physics, etc.). • We prefer candidates with Deep Learning experience, especially when applied to large-scale datasets. Experience with TensorFlow is a plus. • Ability to design an applied research plan for a product family from scratch as evidenced by peer-review publication or similar track record. • Experience on multiple machine learning facets: working with large data sets, model development, statistics, experimentation, data visualization, optimization, software development. • Prior experience with Feature Engineering and putting machine learning models in production is a plus. • Strong working knowledge of Python, Hadoop, SQL, Spark or similar Big Data technologies. • Experience collaborating cross functionally in the development of machine learning products (e.g. Developers, ML Engineers, Product Managers, etc.). • Excellent English communication skills, both written and verbal; the ability to convey your message to team members and other collaborators.
