Job description

Advertising is starting to change. Brands and agencies now buy media through AI agents that negotiate directly with publishers’ agents, in real time and with real budgets. It’s a new way of working, and when a campaign doesn’t perform as expected, there isn’t yet a manual to follow. We’re looking for someone who can work out what’s happening, explain it clearly to the client and make sure it gets fixed.

About pubX

PubX builds agent-to-agent infrastructure for advertising. Our marketplace connects premium publisher inventory with advertiser demand in real time. Advertisers and agencies use our buyer agent, publishers use our seller agent, and people on both sides decide how much autonomy the agents have.

• $5M Series A, led by Chicago Ventures
• Acquisition of Compliant, announced in October
• A live agent-to-agent media buy at Advertising Week New York in October
• Founding member of AgenticAdvertising.org, which is writing the protocols for agentic trading.

The role

You will be the main day-to-day contact for our advertiser and agency clients once they are live. You will work in a small pod alongside our advertiser sales lead and a solutions lead who handles technical onboarding.

You will own

• The client relationship. Keep clients informed about how their campaigns are performing and what we are optimising, and help them continue to grow their spend with us.
• Live campaign troubleshooting. Investigate issues across ad servers and the programmatic stack, using JSON, APIs and campaign data to find the cause.
• Reporting. Make sure performance data is tracked, accessible and clearly explained.
• Getting things done internally. Bring in product, engineering and our publisher team, and represent the client's needs until the issue is resolved.
• You will also join client and agency meetings in and around New York.

How this role has impact

• You will be one of the first people doing this work on the advertiser side, so you will help shape how it is done.
• The role combines client relationships with real technical problem-solving.
• You will work closely with Product and see your feedback influence a new kind of marketplace.

What you will need

• Adtech experience in programmatic or campaign management
• Experience managing clients, whether in account management, customer success, technical account management or solutions consulting
• Working knowledge of ad servers and hands-on experience troubleshooting live campaigns
• Comfort reading JSON and working with APIs
• Strong analytical skills, and the ability to explain technical problems clearly to people who are not technical
• Composure when things are uncertain or moving quickly

The process is a call with our Talent team, an interview with the hiring manager, and a final interview loop of two to three conversations to meet various team members of stakeholders. One of these will be a live, case study based on a realistic client scenario.
