Hi, sorry for the late response. The linked position is for the Fullstack position. We're currently in the process of re-writing this position more clearly as Fullstack position. We're not searching for Frontend-only developers, our Frontend Team is a Fullstack Team (we're called the "App Team").
Thanks for pointing out the salary ranges for Fullstack vs. Backend vs. API. This is indeed not correct and confusing. We value all Engineers on their experience and not on their preferred environment or programming language. I forwarded it!
Also, is there a different salary range? I see a lower range for the frontend position vs backend and API.
