You’ll be building the next generation of app development tools, enabling our merchants to take advantage of advanced AI integration every step of the way from sign-up through app design, launch, optimization, and maintenance over time. You’ll be a true owner, from prototype to production, and work side‑by‑side with product, design, and solutions engineering, all while staying close to merchants to deliver value early and iterate quickly.
