Our goal is to strike a balance that benefits our customers, partners, and company. The Sponsored and Display Ads team at Booking.com leverages Machine Learning to ensure that ad content is high-quality, relevant, and targeted effectively to the appropriate audience.
As a Machine Learning Engineer, your responsibility is to operationalise cutting-edge Machine Learning models that need to run in real-time, ensuring low-latency performance to deliver an exceptional user experience for our travelers, requiring the training of large-scale models and developing scalable feature engineering solutions using modern data and Machine Learning tooling and optimization techniques. You will work closely together with other Machine Learning Engineers and Machine Learnings Scientists as well as with Data Engineers, Software Engineers and Product Managers.

KEY JOB RESPONSIBILITIES AND DUTIES

• Execute applied research plans for machine intelligence on a specific product 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. Document and share the findings.
• Translate specific business problems into ML/AI challenges and identify the best approach within the constraints of the production environment. Build proof-of-concepts to test new ideas and demonstrate their potential value to relevant stakeholders.
• Develop production-grade machine learning code, from models to features and pipelines, allowing for scalability, realtime, monitoring and retraining. Monitor product health, performance and business impact and act accordingly when not met.
• Build readable and reusable code, choosing the right technologies, coding methodologies, and approach from carefully designed rapid prototyping to software deployment at scale. Identify opportunities for platform-based development and reuse by abstracting business problems to generalized ML/AI solutions.
• 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.
• Identify underlying issues and opportunities across domains and situations through application of structured thinking and logic, and formulate possible improvements.
• 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 in areas where they can generate impact.
