Job Description

As an E-Commerce Manager, you will lead end-to-end retail media campaigns across platforms like Amazon, Walmart, and Instacart, owning strategy, activation, optimization, and performance. You’ll translate client briefs into full-funnel plans, drive data-led insights, and present business reviews to senior stakeholders.

• Establish clear performance guardrails (KPIs, learning agenda, optimization cadence) and ensure timely escalation of risks (inventory/OOS, pricing gaps, creative fatigue, tracking/reporting issues).

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.

Leadership & Team Development 

• Lead and mentor Specialists/Coordinators: define priorities, set clear standards, provide coaching, and support development plans.
• Drive consistent ways of working: playbooks, QA checklists, pacing/SOV monitors, naming conventions, change logs, and structured post-mortems to improve performance over time.
• 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).
• Update and approve BCR amounts monthly, ensuring alignment across pacing, invoicing, and finance governance.
