Title and Summary Director, SME Growth Program Management Overview: SMEs are the backbone of the global economy and a key driver of Mastercard’s growth strategy. As both buyers and sellers within the payment ecosystem, they represent a significant opportunity to expand adoption, deepen engagement, and deliver innovative solutions that help businesses thrive. The Director, SME PMO & Strategic Execution will serve as the operational backbone of Mastercard's global SME business across the enterprise, ensuring priorities are translated into coordinated action and measurable outcomes. This role is responsible for driving cross-functional execution, governance, and accountability across the SME organization, partnering closely with senior leaders to align stakeholders, prioritize investments, and maximize business impact. As a trusted advisor and chief integrator, the Director will establish the operating rhythms, performance management processes, and decision-making frameworks that keep strategic initiatives on track. The role requires a highly collaborative leader who can influence across a complex global matrix, anticipate risks and dependencies, and bring teams together around shared objectives. The ideal candidate combines strong business acumen with exceptional program management and stakeholder leadership skills.

About the Role: Tubi's content platform is the engine behind one of the largest free streaming services in the world. Every play, every deal, every creator, every frame of video flows through systems CPE owns, and the surface area is enormous. Distributed services running on the hottest path of Tubi's traffic. Video pipelines processing one of the largest workloads in streaming. Workflow engines automating the operations that used to consume entire teams. Creator-facing products turning a back-office process into a real platform. And on top of all of it, an AI-native rebuild of the CMS that most companies aren't willing to attempt. This isn't a single-domain role. It's a platform where backend, frontend, video, infrastructure, and applied AI all collide at the scale where decisions actually matter, where an architectural choice ripples across millions of titles and billions of requests, and where the difference between "good enough" and "great" shows up in revenue. We're looking for builders who want to range across domains — backend one quarter, frontend the next, applied AI the one after that — and who want their work to be felt: by viewers when a title plays instantly, by creators when they go live the same day, by Content Ops when a workflow runs itself, and by the business when the platform stops being a cost center and starts being a force multiplier. The infrastructure is already there. The mandate is already there. What's missing is the people who want to build the thing, not talk about it. Come build it. This is a hybrid role based out of our Toronto office. You must be willing to travel to our Toronto office two days/week. What You'll Do: You'll work on systems that sit at the heart of Tubi's business, where the content pipeline meets the viewer, the creator, and increasingly, the AI agent. The work spans the full stack of a modern content platform: distributed services, video infrastructure, workflow automation, and applied AI, all running at
