Senior Marketing Specialist

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. This is an ideal role for a highly organized, detail-oriented marketer who loves making things happen.

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 take pride in operational excellence, have strong attention to detail, and proactively identify what needs to happen next. 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.
