Job description

Overview

IQM is seeking an Inventory Partnerships Manager to own and expand supply partnerships for our Demand‑Side Platform (DSP). This role will be responsible for managing relationships with Supply‑Side Platforms (SSPs), optimizing inventory quality and scale, and developing direct partnerships with premium publishers.

This is a founding role, the first hire to build and define the inventory partnerships function from the ground up, including creating a robust internal offering and organizing inventory across 38 categories. You’ll work hands‑on with the product and go‑to‑market teams to shape how inventory is packaged and taken to market, playing an active role in the sales motion as the offering matures. As the business scales, this role has a clear path to building and leading a team, backed by an established and award‑winning DSP.

The ideal candidate has experience in programmatic advertising, SSP integrations, and publisher partnerships, and understands how to grow high‑quality supply within a DSP ecosystem.

This role is hybrid, meaning team members are expected to work one to two days per week in person at one of the office locations in either NY or DC.

At this time, IQM does not sponsor new applicants for employment authorization for this position.

Responsibilities

• Inventory Strategy and Optimization: Analyze traffic coming into the DSP from different SSPs and exchanges. Identify opportunities to improve inventory quality, brand safety, and supply efficiency. Work with AdOps and product teams to troubleshoot inventory or bidstream issues. Develop strategies to increase access to premium inventory and curated marketplaces.
• Publisher Partnerships: Build and manage direct relationships with premium publishers and media owners, including negotiating and managing PMPs (Private Marketplaces) and Programmatic Guaranteed deals. Identify new publisher opportunities aligned with advertiser demand and campaign objectives. Partner closely with Marketing and Sales through a dedicated collaboration model to own the packaging and productization of inventory bundles, libraries, and a dedicated inventory GTM motion that sells inventory from/through IQM.
• Market Intelligence: Track trends in the programmatic supply ecosystem. Maintain knowledge of emerging inventory sources, CTV supply, and curated marketplaces. Provide recommendations on new supply partnerships or inventory channels.
• Internal Collaboration: Work closely with AdOps, Sales, and Product teams to align supply strategy with advertiser demand. Support troubleshooting of supply issues impacting campaign delivery. Collaborate with sales teams in securing premium inventory deals for key clients.

Requirements

• 3–7 years experience in programmatic advertising, DSP/SSP partnerships, or publisher partnerships.
• Strong understanding of the programmatic ecosystem (DSPs, SSPs, exchanges, PMPs, PG deals).
• Experience negotiating and managing inventory deals with SSPs or publishers.
• Analytical mindset with ability to interpret bidstream data and supply metrics.
• Strong relationship management and communication skills.
• Familiarity with OpenRTB, programmatic supply paths, and marketplace dynamics is a plus.
• Experience working at a DSP, SSP, ad exchange, or programmatic media company.
• Existing relationships with SSPs or premium publishers.
• Knowledge of CTV, mobile, and web inventory ecosystems.
