About this role
At Dart, we’re building an AI-native product suite with a world-class user experience—and powerful infrastructure behind the scenes. Our backend is deeply mission-critical, and we’ve invested in a modern stack (Python, Django, Postgres, Redis, REST, AWS) to deliver speed, reliability, and flexibility at scale.
We’re looking for backend engineers who thrive on product complexity, care about performance and correctness, and are excited to work with cutting-edge AI both in what we build and how we build it.
