At Adsquare, we empower marketers and agencies with cutting-edge location intelligence to drive smarter, more effective advertising. As a leader in programmatic solutions, we provide real-time data and insights that enable our clients to reach the right audience at the right time. Our team thrives on innovation, collaboration, and a passion for delivering exceptional client outcomes. If you’re ready to be part of a fast-paced, dynamic environment where your work makes a direct impact, we’d love to hear from you.

Your Profile

  • You have 1-3 years of experience in client success, account management, client development or a similar function within the programmatic/data/ad agency field.

  • Delivering exceptional customer experience and services is in your DNA.
