Role Summary
We are seeking a highly analytical, results-driven Principal, Business Marketing (Search & Google Shopping) to take end-to-end ownership of our paid search engine marketing and shopping channel strategies. In this role, you will manage large budgets across the entire Google ecosystem (Search, Shopping, Performance Max) and Microsoft Advertising.
The ideal candidate embodies Coupang’s Leadership Principles—acting as an owner, diving deep into auction mechanics, systematically optimizing bidding and catalog feed structures, and driving real incremental growth. You will be responsible for scaling net-new GMV, optimizing incremental Return on Ad Spend (iROAS), and working cross-functionally with Analytics, Engineering, Finance, and Category teams to maximize bottom-line profitability. An experimental mindset is essential to learn, innovate, and drive continuous growth. We believe that world-class performance marketing relies on a rigorous "test-and-learn" philosophy
Position : Principal, Business Marketing (Search advertising)
What will you do?
1. High-Precision Campaign Execution & Capital Allocation
- End-to-End Channel Ownership: Strategize, launch, scale, and optimize high-budget Google Search (RSA, DSA), Google Shopping (GSA), Performance Max (PMax), and Microsoft Advertising campaigns with a holistic view of company profitability.
- Bidding Calibration & Optimization: Build scalable processes and feedback mechanisms across all Google bidding mechanics. Apply calibration multipliers to align in-platform bids with true incremental returns.
- Laser-Focused Capital Allocation: Dynamically reallocate daily budget pools between Brand, Non-Brand Search, and Shopping feeds based on margin profiles, unit economics, and peak demand spikes. Eliminate wasteful broad-match spend.
- Zero-Defect Standards : Maintain 100% account hygiene, including tracking parameters (MMP / Google Tag / Conversion Signals), bid caps, feed updates, and negative keyword maintenance.
