[Hiring] Managing Director, Client Partnerships @Infillion

Role Description

We're looking for a Managing Director, Client Partnerships to help grow Infillion's presence across the U.S. market. This is a net new business role: you'll be opening doors with independent and mid-market agencies and brand-direct clients who haven't yet experienced what Infillion's DSP can do, and bringing them in.

You'll be selling something genuinely differentiated. Infillion's open-web DSP is built on MediaMath's programmatic infrastructure and pairs it with value-exchange engagement formats that earn consumer attention rather than interrupt it, Gimbal-powered location intelligence, and Catalina's purchase-based audience data baked directly into the buying workflow. These aren't bolt-ons — they're what makes the Infillion conversation different from every other DSP pitch a buyer hears this year.

This role is national in scope. We care where your relationships are, not where you sit.

What You'll Do

• Prospect, pitch, and close net new business with independent and mid-market agencies and brand-direct advertisers across the U.S.
• Build and manage a pipeline of qualified opportunities from first conversation through signed partnership.
• Lead consultative discovery to understand client-specific challenges and connect Infillion's platform to measurable outcomes.
• Develop and deliver compelling proposals in collaboration with Sales Planning and Solutions Engineering.
• Represent Infillion externally as a programmatic thought leader: at industry events, in trade conversations, and across the advertising community.
• Drive DSP adoption by positioning Infillion's capabilities against real client needs.
• Partner closely with Client Success at close to ensure smooth handoffs and strong account starts.
• Maintain disciplined pipeline hygiene in Salesforce and provide regular, reliable forecast visibility.

Qualifications

• A relationship-driven hunter.
• A dual-threaded seller.
• A platform thinker.
• A self-starter.

What You Bring

• 7–10+ years of programmatic media sales experience, with a demonstrated track record in new business development.
• Established relationships across independent and mid-market agencies and brand-direct advertisers.
• Deep fluency in the programmatic landscape: DSPs, SSPs, identity solutions, data partnerships, and the open web.
• Experience selling multi-layered platforms — you know how to build a value narrative that goes beyond a single product or format.
• Consultative and value-based selling skills; you lead with outcomes and back them up with data.
• Proficiency in Salesforce and a structured, disciplined approach to pipeline management.
• Strong executive presence and presentation skills; you're comfortable in the room with CMOs and senior agency leadership.

Benefits

• Base salary of $175,000–$200,000 plus commission, with on-target annual earnings of $350,000–$400,000.
• 100% company-paid health, dental, and vision coverage for you and your dependents.
• Company-paid life insurance, short-term and long-term disability.
• Unlimited paid time off — we trust your judgment.
• Opportunities for profit sharing, bonuses, and ownership.
• 401(k) plan.
• Cell phone reimbursement.
