Our hot take on AI

We use AI tools. A lot. Claude Cursor Copilotthe whole squad.

Use AI to generate boilerplate code explore architectural patterns refactor legacy systems and speed up development. For example complex data migrations or API scaffolding Let AI handle the repetitive parts while you focus on the system design and business logic that actually matters.

Your expertise is best spent on owning code quality making architectural decisions understanding domain complexity and ensuring the system works correctly under real-world conditionsnot manually writing CRUD endpoints.

We want engineers who use AI like a force multiplierto build faster and explore more options not to replace critical thinking about system design.
