Backend Engineer
Dart AI
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. What You’ll Do Build and scale LLM-powered systems that support agents, AI-assisted planning, chat with tasks/docs, and more Use LLMs and other AI tools in your development workflow to ship faster and with higher quality Design and maintain robust APIs and backend services using Python + Django Optimize data models and queries across a PostgreSQL + Redis foundation Work flexibly and autonomously across a wide range of product and technical challenges Improve existing systems and architect new ones as Dart’s capabilities grow Support and strengthen mission-critical operations as part of a high-ownership team Collaborate closely with frontend, design, and product teams to shape how features are built Participate in user feedback loops and design reviews with leaders and customers Take initiative, move quickly, and learn fast —especially from real usage and live data #J-18808-Ljbffr
