Summary

Who we are
A performance marketing agency that operates as an embedded growth team for our clients. We manage 5+ active accounts across DTC e-commerce, mobile apps (iOS/Android), and lead generation verticals with a combined monthly spend of $200k+. Our primary platform is Meta, with TikTok and Google Ads for select accounts.
We’re a small, senior team - no layers, no bureaucracy. You’ll work directly with the founder (strategy), a creative lead (production), and a PM (coordination). Decisions happen fast, and you’ll have real ownership over the numbers.

The role
You’ll own the full performance lifecycle across multiple accounts - from campaign architecture and bid strategy to creative testing orchestration, anomaly response, and weekly client reporting.
You’ll think in unit economics (CAC, payback period, LTV), plan 1-3 months ahead, and work closely with our creative lead to turn performance data into actionable briefs. When ROAS drops 30% on a Tuesday morning, you’re the one who diagnoses whether it’s creative fatigue, audience saturation, or a platform delivery bug - and you fix it before anyone needs to ask.

What you’ll own

P&L outcomes
Hit and scale ROAS/MER targets per client while holding CAC and payback period within agreed thresholds
Manage daily budgets and pacing across multiple ad accounts per client
Own scaling decisions: when to push, when to pull back, how to manage learning phases

Strategic planning
Rolling 1-3 month media plans: angles, offers, campaign structure, budget allocation
Test roadmaps: creatives, audiences, placements, bid strategies - planned and executed weekly
Map full funnel TOF/MOF/BOF and ensure message match from ads through LP/PDP/app store to email/SMS

Creative analysis and guidance
Analyze creative performance using hook rate, hold rate, CTR, CVR, CPA, and ROAS to identify winners, fatiguing assets, and patterns worth iterating on
Translate data into specific, actionable briefs for the creative team: what formats to build (video, static, carousel, UGC), what angles to test, what volumes are needed, and what the priority order is
Define test mix and cadence - you decide what gets launched, how much budget it gets, and when to kill or scale
QA all creatives before launch: copy accuracy, size compliance, ad platform policy, landing page alignment

Tracking and measurement
Implement and maintain tracking: Pixel, CAPI, AEM, UTMs, GA4/GTM
For mobile app clients: configure and verify MMP (Mobile Measurement Partner) attribution, set up in-app event tracking, manage postback configurations, and ensure accurate install/purchase/subscription attribution across iOS and Android
Diagnose discrepancies between ad platform reporting, MMP data, and backend numbers
Maintain clean attribution across web and app funnels

Optimization and troubleshooting
Prevent creative fatigue through proactive refresh cycles
Manage bid strategy transitions and campaign structure decisions (ASC/ABO/CBO mix, Cost Cap vs Bid Cap)
Diagnose delivery issues, attribution discrepancies, and platform anomalies
Coordinate CRO and landing page fixes when data points to post-click problems
Define stop-loss thresholds and enforce them

Reporting and visibility
Weekly client reports: campaign-level breakdowns with strategic commentary, trends, risks, forecast, and next steps
Surface risks early - don’t wait for the weekly report to flag a problem
Maintain dashboards and ensure stakeholders have clear visibility into performance
Enforce Meta policy and FTC/ASA compliance across all ad content

KPIs
MER/ROAS per client
CAC and payback period
Creative hit rate and time-to-winner
Budget pacing accuracy
Report quality and on-time delivery
On-schedule test execution (planned vs launched)

Requirements

Must have
4-6+ years of hands-on Meta Ads buying with proven profitable scale at $200k+/month combined spend
Fluent in unit economics and forecasting: CAC, LTV, payback period, MER, contribution margin
Strong attribution knowledge: CAPI, AEM, GA4/GTM, MMP setup and troubleshooting
Proven ability to analyze creative performance data and turn it into actionable briefs and testing plans for the creative team
Experience with both DTC/e-commerce and mobile app campaigns (including app install and in-app event optimization)
Excellent English - you’ll write client-facing reports and communicate async in Slack
Self-directed, proactive, ownership mindset

Strong plus
TikTok Ads and/or Google Ads buying experience
Multi-language campaign management (English, Spanish, French)
Shopify/Replo/Webflow CRO knowledge
Multi-country buying experience
Triple Whale, Hyros, Northbeam, Adjust, or similar attribution platforms

What we offer
Performance-based compensation: base retainer + upside tied to ROI/MER performance
In-house creative team and testing budgets
Standardized ops: weekly report templates, creative brief system, structured testing frameworks
Remote, async-first, high-autonomy environment
Small team with direct access to decision-makers - no red tape

Additional questions:
1. Your best Meta Ads case study - what you managed, what decisions you made, what results you drove
2. A specific example of how you turned performance data into a creative brief that improved results
3. Your experience with mobile app campaigns (if any)
4. Your availability and compensation expectations
