About The Position

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. 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.

Requirements

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.
Sufficient knowledge of English to have professional verbal and written exchanges in this language since the performance of the duties related to this position requires frequent and regular communication with colleagues and partners located worldwide and whose common language is English.

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.

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