Own end-to-end campaign governance: creative requirements and QA, tracking/tagging (where applicable), flighting, budget allocations, pacing, keyword/bid/audience optimization, and ongoing brand safety + compliance checks.
Establish clear performance guardrails (KPIs, learning agenda, optimization cadence) and ensure timely escalation of risks (inventory/OOS, pricing gaps, creative fatigue, tracking/reporting issues).

Strategy & Planning

Translate client briefs into channel strategy and full-funnel plans: audience frameworks, targeting approach, measurement plan, and a structured testing roadmap (A/B tests, incrementality/lift, geo tests, creative tests).

Own cross-platform reporting and insights across Walmart, Instacart, Criteo, Loblaws (MediaAisle) and other platform UIs; ensure clean data, consistent definitions, and executive-ready reports.
Turn performance into a clear narrative: what happened, why it happened, what we learned, and what we’re doing next with actionable recommendations and quantified impact.

Client-Facing Ownership

Lead client communications and governance: set expectations, manage approvals and timelines, and proactively communicate trade-offs, risks, and recommended actions to senior stakeholders.
Present monthly business reviews and QBRs with a crisp story that ties media performance to business goals and identifies next-step decisions.

Partner & Cross-Functional Management

Manage senior relationships with Amazon, Walmart, Instacart, Criteo, Loblaws, and other partners/vendors to unlock opportunities, troubleshoot issues, and drive performance improvements.

Responsible for entering media buy inputs into Prisma in a timely manner, and coaching/teaching new team members and Coordinators on Prisma billing processes and best practices.
Ensure budget accuracy within PM media finance systems (including reconciliation checks and timely updates aligned to approved plans).
