Job Description

Salesforce is the global leader in Cloud-based (SaaS) solutions that enable the world’s premier brands to maintain a robust online presence with high ROI. We do that by providing a highly scalable, integrated cloud platform that allows our clients to rapidly launch and manage multiple e-commerce stores, initiate unique marketing campaigns, and drive customer traffic across a global footprint.

We are looking for a top-notch machine learning scientist/data scientist to join the machine learning science team of our customer 360 personalization effort. Our team is tasked with producing performant machine learning models to enhance and personalize the shopper experience through search, product recommendations, content personalization, promotion selection, and much more. In addition, we augment and automate the work of the merchandiser and admins to enable them to react faster and better to changing markets, trends, and customer demands. You will be responsible for turning business needs into machine learning solutions that we can deploy to production in collaboration with our engineering teams. To achieve this, you will research, design, prototype, and build machine learning systems, with large-scale training and offline/online tuning and experimentation.

The successful candidate will work with world-class database gurus, software and machine learning engineers, research scientists, and fellow machine learning scientist. We are looking for someone who gets a kick out of staying on top of the latest machine learning literature/tools/techniques and figuring out the best way to apply these for practical solutions. We encourage contribution to tools and knowledge sharing within the team, the company, and the industry.

Responsibilities

• Work with product management and leadership to translate business problems to data science problems
• Research, prototype, and build demonstrations of machine learning ideas for quick validation and feedback
