Senior Copywriter

About the role

We're hiring a Senior Copywriter to lead creative development for our primarily B2B client roster and to directly manage our Copywriter. This role requires extensive experience translating complex SaaS products, technical capabilities, and business value into clear, persuasive messaging for sophisticated decision-makers and buying committees. You should be as comfortable building a concept deck as you are turning a complex product into copy that converts.

It’s a collaborative place made up of small, closely knit and versatile teams that are fast and adaptive to solve problems and build systems.
