• Work on Taboola's recommendations ad formats serving and user experience - the backbone of the company's products, standing at the intersection of end-users, publishers and advertisers
• Develop and maintain a variety of new & innovative ad formats that reach billions of users and are used by thousands of advertisers (carousel, app install, video ads and many more)
