Senior Director, Supply Partnerships

Location: New York

The opportunity

Unity is building a new team to unlock the next chapter of its supply strategy: expanding the Unity Ads SDK and Level Play mediation platform beyond gaming into non-gaming apps, streaming TV, premium web, and emerging channels. As Senior Director, Supply Partnerships, you will be the founding leader of this team — defining the strategy, recruiting the talent, and personally driving relationships and execution with the most important publishers and platform partners in the market.

You will operate at the intersection of enterprise sales, partnership product strategy, and market development, partnering closely with Unity's product, data science/ML, engineering and sales teams. This is a high-visibility role with a direct line to senior leadership and a mandate to materially grow Unity's supply footprint outside of gaming.

What you'll be doing

Define and execute Unity's non-gaming supply strategy across mobile apps (lifestyle, entertainment, fintech, utilities, social), streaming TV/CTV, and premium web.

Build, lead, and mentor a team of Supply Sales Executives and Supply Integration Managers for non-gaming; set team goals, manage performance, and develop career growth paths.

Own and cultivate executive-level relationships with top-tier publishers, app developers, OEMs, and platform partners across target verticals.

Drive commercial negotiations for SDK integrations, mediation partnerships, and direct supply agreements; manage contracts from prospecting through close.

Develop a clear GTM playbook for non-gaming supply acquisition, including ICP definition, outreach frameworks, onboarding processes, and success metrics.

Serve as the internal voice of the publisher: advocate for the product features, integrations, and support structures that allow Unity to compete for premium non-gaming inventory and perform well for publishers.

Partner with the demand side of Unity Ads and programmatic teams to ensure supply quality, audience data richness, and yield optimization for non-gaming publishers.

Build strategic relationships with mediation platforms, header bidding solutions, and SSP partners to position Unity as a top demand source in non-gaming auctions.

Represent Unity at industry events and establish Unity's credibility with non-gaming publishers in the market.

Provide regular executive reporting on pipeline health, revenue contribution, and strategic partnership status.

What we're looking for
12+ years of experience in supply-side partnerships, business development, or publisher development in advertising, ad tech, or programmatic media, with tangible expertise in the mobile space.

Demonstrated success leading supply growth teams at a mobile ad network, DSP, SSP, or mobile measurement platform; experience expanding supply beyond core verticals strongly preferred.

Deep understanding of the mobile in-app advertising ecosystem: SDK monetization, mediation (MAX, AdMob, Level Play), RTB/programmatic and header bidding.

Experience selling to or partnering with non-gaming app publishers (e.g., streaming, social, fintech, lifestyle) and/or CTV/OTT platforms is a strong differentiator.

Executive presence and gravitas; comfortable navigating C-suite conversations with major publishers and negotiating complex, multi-year commercial agreements.

Proven team-builder with experience hiring, developing, and retaining high-performing supply and BD professionals.

Strategic thinker who can translate market opportunity into a structured, executable go-to-market plan with measurable milestones.

Excellent cross-functional collaborator; experienced working with product, engineering, sales development representatives and revenue operations to bring partner feedback into the product roadmap.

Familiarity with privacy-first advertising trends (SKAdNetwork, ATT, contextual targeting) and their implications for publisher monetization.

Preferred qualifications

Experience at App Lovin, Moloco, Liftoff, Iron Source, iron Source by Unity, Digital Turbine, Magnite, Pubmatic, or similar supply-focused ad tech platforms.

Existing relationships with non-gaming publisher decision-makers in streaming, social, or app categories.
