Software Engineer II

The Software Engineer-II for Ads builds the data, analytics, and product experiences that help Merchants and Brands understand advertising performance and decide where to invest next. This role will strengthen the Ads experience across the customer-facing Brand Experience platform and the internal Merchant Station platform by turning complex advertising data and business logic into clear, actionable insights.

Ads, together with DART and margin calculators, is a critical input into day-to-day Merchant decisions. The current Ads experience is one of the least-used areas in Brand Experience because it does not yet provide essential data, including keyword-level detail, or a compelling explanation of performance. This engineer will help overhaul that experience, support rapid proofs of concept, and build scalable capabilities that contribute to Merchandising's goal in additional programmatic Brand support across Ads, Promotions, and Pricing Support.

• Delivers a significantly improved Ads experience in Brand Experience and Merchant Station, increasing engagement with a page that currently has the lowest usage on the platform.

• Provides Merchants and Brands with accurate, decision-ready advertising data, including keyword-level performance insights.

• Enables Merchants to audit advertising spend, explain the impact of Project Astra, and present a clear story about the company's advertising strategy and results.

• Builds actionable recommendations that help Brands understand when and where additional advertising investment can create value.

• Runs focused proofs of concept quickly, incorporates feedback, and scales successful approaches into reliable product capabilities.

• Contributes to Merchandising's goal of securing $1 million in additional programmatic Brand support across Ads, Promotions, and Pricing Support.

• Improves the reliability, clarity, and usability of advertising data across both internal and Brand-facing workflows.
