We're looking for a Media Buyer to own and scale paid acquisition, with Google Ads and Meta Ads as our core channels.

Your primary focus will be acquiring our defined ICP at the highest quality and lowest sustainable cost. We expect approximately 80% of your effort to go toward improving acquisition within this core audience, and 20% toward testing adjacent audiences, regions, and emerging opportunities such as CTV, OpenAI Ads, and other new channels.

This is not a role for someone who simply launches campaigns and optimizes toward what advertising platforms report. We are looking for a hands‑on operator who can connect paid media performance to vigente company outcomes, determine whether advertising is creating incremental growth, make informed budget allocation decisions, and turn performance insights into better creative.

You will operate at the intersection of paid acquisition, measurement, experimentation, creative strategy, and business performance.

What You'll OwnPaid Acquisition

- Own paid acquisition strategy and hands‑on execution across Google Ads and Meta Ads, from campaign structure and bidding to testing, optimization, and scaling.
- Focus approximately 80% of your effort on acquiring our defined ICP at the highest quality and lowest sustainable cost, and 20% on testing adjacent audiences, regions, and emerging opportunities.
- Build and maintain a structured testing roadmap across audiences, offers,



landing pages, creatives, bidding approaches, and campaign structures.
- Allocate and scale budgets based on CAC, LTV, payback, customer quality, and incremental business impact — not platform‑reported ROAS alone.
- Evaluate and test emerging acquisition channels such as CTV, OpenAI Ads, and other platforms when the opportunity and economics justify it.

Measurement & Incrementality

- Connect advertising‑platform performance with GA4, Google Tag Manager, BigQuery, and company‑level customer and revenue data to understand actual business impact.
- Measure acquisition beyond platform‑reported CPA or ROAS, focusing on customer quality, paid conversion, revenue, CAC, LTV, payback, and incremental contribution.
- Identify and investigate discrepancies between advertising platforms, analytics, attribution systems, and internal company data.
- Design and interpret incrementality tests, including holdouts, geo experiments, and lift studies, to determine which spend is actually driving new customers.
- Challenge attribution and budget decisions when platform‑reported performance does not align with actual company performance.

Creative Strategy & Performance

- Own the creative performance loop from campaign data to the next creative test.
- Identify winning and declining hooks, angles, messages, formats, offers,



and audience insights from performance data.
- Turn those insights into clear creative briefs, concepts, hooks, ad copy, and video scripts.
- Direct and prioritize creative production with designers and video creators based on campaign needs, testing priorities, and performance.
- Continuously test and iterate creative concepts, using performance data and AI tools to accelerate research, ideation, scripting, and learning.

How You'll Think About Performance

We expect you to look beyond advertising‑platform metrics and understand the full acquisition system.

You should be comfortable evaluating performance through the metrics that matter most to customer quality and business impact:

- Activation quality
- Paid conversion
- Revenue / MRR
- LTV and payback
- Incremental CAC

If Meta or Google reports strong performance while company revenue or MRR is moving in the opposite direction, we expect you to investigate why — not simply trust the platform attribution.

Responsibilities

- Run paid acquisition hands‑on every day, with Google Ads as the core channel, owning campaign structure, bidding, testing, optimization, and scaling.
- Focus approximately 80% of your effort on acquiring our defined ICP at the highest quality and lowest sustainable cost, and 20% on testing adjacent audiences, regions, and emerging channels.
- Allocate budget across channels and regions based on CAC, LTV, payback, customer quality, and incremental impact — not platform‑reported ROAS alone.
- Design and interpret incrementality tests, including holdouts, geo experiments, and lift studies, to determine which spend is actually driving new customers.
