Backend Engineer

Role: Backend Engineer Location: Fully Remote (Headquarters in Boston, MA) Working Hours: 9-5 EST Onsite: Travel every 8-10 weeks for a multi-day onsite

You'll build and maintain the backend systems at the core of a real-time learning AI: the APIs and data pipelines that connect live user and merchant behavior to systems that learn from it. You'll work alongside exceptional AI researchers and engineers, with real autonomy to shape how that architecture evolves.

This is a hands-on, AI-native engineering role. You'll need to subscribe to agentic-led development. You'll use agentic coding tools daily, including managing multiple parallel coding sessions, to move quickly through a complex and fast-changing codebase. You'll be trusted with context and the freedom to decide how to use it, not handed a task list.
