About Mercury

Mercury is on a mission to defy those expectations. We're a financial technology company that helps startups spend less time banking* and more time building. We believe that the key to our success revolves around thoughtful design — and we hold the craft of that design to an exceptionally high standard. We're looking for a Staff Brand Designer who sets that bar: someone whose eye is so precise, and whose execution is so considered, that the work around them gets better just by virtue of their presence.
