Digital Marketing Manager

Mosaic Biosciences is a biotherapeutics drug discovery company that partners with biopharmaceutical companies to discover novel protein and antibody therapeutics. Our experienced and dedicated research teams collaborate with our partners to design, manage, and execute research programs to rapidly advance clinical candidates, starting at any point from early discovery into preclinical development. We are building our marketing function to match the pace of our science.

Position Overview

As the Digital Marketing Manager, you will run Mosaic’s digital channels and turn them into qualified leads. You own how buyers find us in search and in AI answers, how they experience our website, and how we reach them through paid media, email, and social. You will also support Mosaic's growth in Europe, working with our European business development lead to reach buyers in the region.

The best candidate is creative and analytical: a storyteller who is also fluent in web platforms, analytics, and paid media. You report on all of it and are measured on pipeline, not activity. This is a hands-on role on a two-person team. You will work closely with the Director of Marketing, Business Development, the Scientific team, and our inside sales representative.
