About Split Rocket

Split Rocket is a full-service e-commerce marketing agency helping brands scale from $5–10 million to $20 million+ in annual revenue.

We manage paid media across Meta, Google, and TikTok for multiple e-commerce brands, and we're expanding our media team.

About the Role

We're hiring a Senior Media Buyer who thinks like a growth operator, not just a platform specialist.

You'll own the strategy, execution, and profitability of a portfolio of e-commerce accounts. This includes forecasting advertising spend, revenue, and contribution margin, managing combined monthly budgets exceeding USD $200,000, and maintaining reliable performance measurement.

You'll lead client conversations around growth strategy, identify testing and expansion opportunities, and take ownership of results across the accounts you manage.

You'll report to our Chief Execution Officer, who will partner with you on strategic planning and direction. You'll also mentor one or two junior media buyers.

This is a full-time, remote position open to candidates based in Brazil who can consistently work US Eastern business hours.

Advanced English proficiency is mandatory. All client meetings, internal communication, performance reporting, and strategic presentations are conducted in English. Candidates must have professional fluency in both spoken and written English, equivalent to C1 or C2 level.

Our Approach: Profitable Growth, Not Just ROAS

Our clients are typically e-commerce brands generating $5–20 million in annual revenue. At this stage, in-platform ROAS can look healthy even when the underlying business isn't generating sufficient profit.

Your responsibility is to help clients grow profitably by:

• Managing performance against business metrics, including MER, new-customer CAC, contribution margin after ad spend, and cash payback period, rather than relying exclusively on platform ROAS.
• Understanding each client's unit economics, including COGS, AOV, LTV, discounting, and return rates.
• Establishing advertising spend limits based on profitability and cash-flow constraints.
• Forecasting revenue and contribution margin to support data-driven budget recommendations.
• Identifying when advertising channels may be taking credit for conversions that would have occurred organically, and using incrementality testing to evaluate impact.
• Advising clients when to scale, maintain, or reduce advertising investment based on business performance.

Key Responsibilities

Media Buying & Performance Management

• Build monthly advertising spend and revenue forecasts for each account using historical performance and client goals.
• Plan, launch, manage, and optimize campaigns across Meta, Google Ads (Search, Shopping, Performance Max, YouTube), and TikTok.

• Develop and refine full-funnel campaign strategies, including audiences, bidding, budgets, placements, and creative rotation.

• Strong analytical skills and experience with Google Sheets, Excel, GA4, and performance reporting platforms.

• Experience using automation and AI tools to streamline reporting, campaign operations, and creative testing.
• Familiarity with Shopify data and e-commerce analytics tools such as Triple Whale, Northbeam, or Klaviyo.
