Full-Stack Engineer (L2)

MerchantSpring is a SaaS analytics and reporting platform that helps agencies, investors, brands, and vendors track and optimize performance across more than 120 e-commerce and marketplace channels, including Amazon, Walmart, and Shopify. Working at the intersection of software, data, and commerce, the team builds tools that help customers make sense of complex performance signals and act on them with confidence. We're seeking a Full-Stack Engineer who enjoys hands-on development across the stack — building responsive React interfaces, scalable Node.js/TypeScript services, and the data layer that powers reporting across 120+ marketplaces. In this role, you'll ship features end-to-end, work with large volumes of real marketplace data, and help keep the platform fast, reliable, and easy to build on. You'll join one of our focused squads — AI, ETL, or API — working alongside product, QA, and fellow engineers in a modern, cloud-native, AI-native environment. This is a great opportunity for someone who cares about clean, maintainable code, enjoys solving real-world data and scale challenges, and wants to grow their craft on a platform that thousands of sellers and agencies rely on every day.
