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. Essential Duties include but are not limited to the following:  This role will focus its energy where commercial leverage is highest, and reflect a blend of the following: * Segment Narrative and Market Thesis: * Develop and maintain application area narratives that articulate the problem, limitations of status quo, Cellanome advantage, supporting proof, and urgency for each market segment. * Partner with Corporate Marketing on segment GTM strategy to co-design and align segment-level market theses with Cellanome’s overarching corporate brand, theme calendar, and demand generation engine. * Lead presence buildout in key application areas in close partnership with Applications Product Management, R&D, and Scientific Affairs to ensure narratives are scientifically grounded and commercially sharp. * Content Development: * Drive high-authority content creation by owning the end-to-end segment content strategy and authoring specific, data-grounded assets (including blog posts, application area pages, conference presentations, ROI frameworks, and case studies) tailored for a skeptical scientific audience. * Collaborate closely with Corporate Marketing to optimize segment content for high-impact channel distribution, and with Applications and Platform Product Management on launches, competitive positioning, product- and technology- level content and sales enablement.  * KOL and Scientific Community Relationships:  * Identify and support key opinion leaders (KOL) & early access placement sites who can open target markets and build relationships that generate credible, public proof points.  * Structure collaborations and publications to support market adoption in partnership with Collaboration Scientists, Scientific Affairs, the account teams, and leadership.  * Own the marketing side of select KOL relationships, ensuring visibility and impact of collaborations across channels.  * Sales Enablement:  * Develop and maintain segment-specific sales enablement materials including talk tracks, objection handling guides, qualification criteria, and "why now, why us" framing for each application area.  * Partner with Sales on market development, early funnel building, and specific opportunities as appropriate.  * Market Intelligence:  * Maintain a current view of key segment landscapes, shifting market dynamics and customer needs, and emerging application areas.  * Synthesize intelligence into actionable inputs for Sales, Product, and leadership with clear implications and recommended actions. * Strong presentation and communication skills. * Ability to travel up to 30% of working time away from work location, may include overnight and/or weekend travel at times.  * Ability to work in front of a computer screen and/or perform typing for approximately 90% of a typical working day. Minimum Qualifications:  * Typically requires a minimum of 15 years of related experience with a Bachelor’s degree; or 12 years and a Master’s degree; or a PhD with 8 years experience; or equivalent experience.  * Deep fluency in immunology, neurobiology, immune-oncology, functional screening, cell biology, single-cell genomics, and/or functional cell assays. * Demonstrated ability to build a market narrative from scratch: segment thesis, proof point architecture, and the content stack that moves buyers from awareness to conviction. * Exceptional scientific communication skills, with the ability to produce content that working biologists read and trust. * Track record of driving cross-functional alignment without direct authority: getting Scientific Affairs, Sales, and Product moving in the same direction on shared evidence and narrative priorities. * Experience producing senior-quality output independently, without a large team or agency infrastructure to rely on. * Demonstrated ability to perform the essential duties of the position with or without reasonable accommodations.  Preferred Qualifications:  * Experience building GTM infrastructure for an emerging or nascent category, not just executing playbooks for established markets. * Fluency with AI tools as a practical force multiplier for research, drafting, and content production. * Experience structuring or influencing scientific collaborations and KOL relationships for commercial or market development purposes.  The estimated base salary range for this position is $190,000 - $240,000/year. Within the range, individual pay is determined by work location and additional factors including job related skills, experience, and relevant education or training.   What you can expect from us: You’ll feel the energy when you walk in our door – we work hard, we have fun and we have ambitious plans to grow.
