Director, Segment Marketing & Market Development

Cellanome•San Diego, CA

4h•$190,000 - $240,000•Onsite

About The Position

We’re a well-funded start-up. You’ll get a chance to wear many hats, be a part of a growing team, and have the potential for exciting financial and career growth. Here’s what sets us apart. We’ve set our sights on some of the biggest challenges facing biology today. We’re amassing a world class team of engineers, scientists, team builders and problem solvers to tackle these challenges heads-on. We’re passionate about developing the next generation technologies that will unravel the complexities of biology. This is a unique opportunity to build, be part of an exciting start-up and be surrounded by good humans who are super capable, humble and down-to- earth. The Director, Segment Marketing & Market Development, will be an architect and builder of Cellanome's market-building efforts. This role will help prioritize which segments to pursue, determine what evidence buyers need to move from curiosity to conviction, and produce the scientific and commercial content that closes that gap. This role moves fast: forming sharp hypotheses about what markets need to believe, testing them quickly through content and customer conversations, learning from what lands, and iterating. This is less a research-and-plan role, more a build-and-learn one. Reporting to the SVP, Marketing & Strategy, this role will drive the segment-level buying journey and go-to-market (GTM): building the case for a new category of measurement, educating early-adopter scientists and research & commercial leaders on what becomes possible with same-cell, longitudinal multimodal data, and positioning Cellanome as the platform of choice for their application area. This is an on-site role to be based in either our Foster City, CA or San Diego, CA offices.

Exceptional scientific communication skills, with the ability to produce content that working biologists read and trust.

Strong presentation and communication skills.
