About The Position

BigCommerce is seeking a Senior Software Engineer (AI Specialization) to help us build powerful product experiences using intelligent AI agents. You’ll be at the forefront of defining how users interact with our products through natural language, by designing agent-based systems that unify and act on data from various Commerce products (BigCommerce, Makeswift, B2B and B2C) and partner systems. BigCommerce, part of the Commerce brand family, helps merchants increase sales at every stage of their growth. From small startups to mid-market businesses and large enterprises, we provide the leading e-commerce platform. Our customers can then concentrate on what's most important: growing their businesses. We enable our customers to build, innovate, and grow, collectively reshaping the e-commerce industry. At Makeswift we're on a mission to build the best tool for creative minds to bring their ideas to the world. The concept is simple: combine the experience of a buttery-smooth, elegant design tool with the infrastructure required to go to production. Instead of mocking up static images and prototypes, build production-ready websites out of live components. Growing team? Version control and real-time collaboration. Working with React engineers? Reuse their work by integrating existing components directly into Makeswift. Our vision is to open up our APIs and foster a component ecosystem that will bridge the gap between developers and designers.
