About SmartCommerce

SmartCommerce helps brands turn demand into real retail performance. SmartCommerce connects websites, media, and marketing campaigns directly to retailer carts with Click2Cart® - helping more shoppers convert while protecting performance as availability changes. We turn product discovery on your site into retail purchases by helping you route shoppers to in-stock retailers and protect conversion when inventory shifts. We connect ads, social, influencers, retail media, and QR codes directly to retailer carts so campaigns convert beyond the click. We understand how marketing drives retail outcomes and help you see which retailers convert, where availability impacts performance, and how campaigns perform across commerce channels.

We’re building the technology that connects media, shoppers, and retailers — and we’re looking for people who want to help shape the future of commerce.

• Write clean, tested, well-documented code and actively participate in code reviews
• Leverage AI coding tools (Claude, Cursor, Codex, Gemini, etc.) to accelerate development and improve code quality
• Mentor other engineers on backend and data engineering best practices
