This is not a narrow role. It’s a playground for builders .

You’ll thrive here if you…

Love turning complexity into simplicity

Care about UX as much as clean code

Prefer ownership over instructions

Move fast, learn fast, and fix things instead of debating them

Actually want to build , not just talk about building
