Senior Director, Supply Partnerships

About the role

The opportunity Unity is building a new team to unlock the next chapter of its supply strategy: expanding the Unity Ads SDK and LevelPlay 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.

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, LevelPlay), 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 AppLovin, Moloco, Liftoff, IronSource, ironSource 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.
• Experience expanding supply partnerships into CTV, OTT, or premium web environments.
• AI capabilities: comfortable leveraging AI tools and deploying across their team to perform major tasks.
