Freelance Marketing Consultant

As a Senior Marketing Specialist at BillionToOne, you will play a critical role in bringing our marketing programs to life across channels. You will support the Marketing team by owning the day-to-day execution of marketing campaigns, managing our library of customer-facing collateral, coordinating projects and workflows, and helping ensure high-quality work moves efficiently from concept through launch.

You are equally comfortable managing multiple projects, coordinating with creative and cross-functional partners, building an email campaign, proofing a customer-facing asset, or developing engaging social content. You will work closely with the rest of the Marketing team and other cross-functional partners and will have the opportunity to develop broad experience across marketing channels in a fast-growing healthcare company. This role may be remote or based out of our Menlo Park or Union City, CA offices and reports to the Marketing Operations Manager.
