About this role

Senior Infrastructure Security Engineer United States About Matter Labs Matter Labs builds private settlement infrastructure that lets regulated institutions settle directly with each other without exposing data, ceding control, or waiting days.

Matter Labs runs a deliberately lean, high-leverage
