Are you ready to join the programmatic evolution?

Index Exchange is seeking an Account Manager to join our US HoldCo team. In this role, you will maintain direct ownership of key agency and marketer partnerships. You will balance hands-on client delivery with consistent service standards, timely execution, and strong collaboration across the team. Acting as a trusted partner, you’ll proactively address client needs, solve challenges, and surface opportunities for growth.

This role is ideal for someone who thrives in an ambiguous, fast-paced environment, excels at building relationships, and is passionate about developing others.

What we’re looking for:

• Strategic: Index values partnerships and providing strategic insights to the agencies and marketers who leverage our exchange. In this role, you will be responsible for not only day-to-day account management and operations, but also for providing insights and recommendations to our external stakeholders around the programmatic ecosystem as a whole. You’ll bring a strong point of view and help your team do the same.

• Collaborative: In order to retain and grow our agency accounts, you will work cross-functionally with sales, analytics, technical teams, and publisher account teams to become a subject matter expert on the Index Platform. You’ll also foster that same collaborative spirit within your team, creating an environment of shared learning and accountability.

• Communicative: You will be working with a number of clients and internal stakeholders at any given time, and will be expected to communicate effectively both internally and externally. This is a highly visible, client-facing role where building trusted relationships with agencies and marketers is essential. You’ll also serve as a clear, confident voice that elevates the work of your team.

• People-First Leader: You bring a people-leadership mindset to everything you do. You guide day-to-day operations, provide mentorship, and help create a culture of accountability and growth. You’re comfortable navigating ambiguity, modeling adaptability for your team, and stepping in where needed to ensure your partners receive exceptional service.

Here’s what you’ll be doing:

• Maintain direct ownership of a portfolio of key agency and marketer partnerships, delivering exceptional service and strategic guidance.

• Serve as the day-to-day contact for existing agency and brand marketer partners, while delivering expertise in the Index platform.

• Ability to thrive in an ambiguous environment — you’re comfortable operating without a perfect playbook and can bring clarity and direction to your team when needed.

• Strong communication and storytelling skills — ability to be clear and compelling when presenting internally and externally, with the ability to tailor your message to different audiences.

• Expert-level adaptability: you navigate change with confidence and help others do the same.
