THE ROLE

We’re looking for a Paid Media Manager to own paid performance and drive revenue growth across our brand portfolio.

This is not just about managing spend.

This is about architecting growth. Understanding how creative, targeting, and platform mechanics work together. Turning data into leverage.

You’ll develop, execute, and optimize paid strategies across social, search, and emerging channels - partnering closely with Client Success and Production to ensure performance drives real business outcomes.

Paid isn’t separate from the work.

It’s how the work scales.

WHAT YOU'LL DO

Build the Strategy

Develop cross-platform paid media strategies across Meta, TikTok, Google, YouTube, and emerging ad networks.
Align media plans with broader brand and commerce objectives.
Design for scale from day one.

Own Execution End-to-End

Own campaign setup across targeting, structure, creative inputs, bidding strategy, and tracking.
Ensure every campaign is built intentionally - not reactively.
Balance efficiency with experimentation.

Optimize for Growth

Continuously analyze performance data and identify actionable optimizations.
Refine audience strategy, creative mix, placements, and spend allocation.
Maximize ROAS while building long-term learning and scale.

Partner Cross-Functionally

Work closely with Client Success to support brand partners with performance strategy and insights.
Collaborate with creative teams to ensure paid and content are aligned.
Bring performance intelligence into client and internal strategic conversations.

Test What’s Next

Stay ahead of platform shifts, beta opportunities, and new ad formats.
Experiment with new channels and bidding strategies.
Build repeatable testing frameworks that compound learning.

Own Reporting & Accountability

Lead reporting across campaigns with clear, actionable insights.
Translate dashboards into narratives stakeholders understand.
Tie paid performance directly to revenue, GMV, and growth impact.

WHAT WE'RE LOOKING FOR

3+ years managing paid media across social, search, or programmatic platforms.
Strong track record driving performance outcomes: e-commerce conversion, lead generation, audience growth, etc.
Deep familiarity with Meta Ads Manager, Google Ads, TikTok Ads, YouTube, and related tools.
Strong analytical instincts and comfort working directly in performance data.
Experience managing and optimizing meaningful media budgets.
Ability to operate cross-functionally in fast-moving environments
Clear communicator who can translate complexity into clarity.

NICE TO HAVES

Experience in social commerce, creator-driven performance, or influencer amplification.
Hands-on experience with Google Analytics, Looker, Airtable, and CRM platforms.
Knowledge of CRO principles and structured A/B testing frameworks.
Experience in a high-growth, digital-first company.

WHO YOU ARE

You think in systems, not just campaigns.
You care about efficiency - but prioritize scale
You move quickly, but you test thoughtfully.
You’re comfortable owning numbers and performance
You take accountability for outcomes.

WHY THIS ROLE MATTERS

In a platform-first world, paid media is leverage.

It’s what turns strong creative into sustained growth.

It’s what turns momentum into revenue.

This role ensures we don’t just participate in the platforms - we win inside them.
