About Probably Genetic
Probably Genetic is changing the lives of patients living with severe, complex diseases. Our data platform is used by drug developers and patient advocacy groups to develop and launch treatments for these patients. Our technology discovers undiagnosed patients online, analyzes their disease state using machine learning and at-home testing, and enables compliant communication with patients. In doing so, we help patients access diagnoses, clinical trials, and treatments as early as possible.
We are a tight-knit group of hard-working, ambitious problem solvers united by a mission greater than ourselves. We do well by doing right by patients. We are developing some of the most cutting-edge solutions in healthcare, and our roadmap is packed with innovations in bioinformatics, AI, and drug development. We have built a lean, all-star team to help us bring our vision to life, and we want you to be a part of it.
Probably Genetic has raised multiple rounds of funding from Silicon Valley’s best investors, including Threshold, Khosla, and Y Combinator, and offer competitive salaries, comprehensive benefits, and meaningful early stage equity.
About the Role
We’re looking for a Head of Marketing reporting directly to our CEO to lead and develop our entire marketing team — from performance marketing to brand, integrated campaigns, and patient experience. This is a hands-on leadership role for someone who is deeply fluent in metrics and experimentation, but who also understands how brand, trust, and storytelling drive long-term growth in healthcare.
You’ll operate with deep scope and influence and serve as a critical member of the leadership team
What You’ll Do
Growth & Performance Marketing
Own patient acquisition strategy across paid, organic, and lifecycle channels (e.g., paid search/social, SEO, partnerships, email, CRO, and AI tools).
Design and run rigorous experimentation programs (A/B testing, cohort analysis, funnel optimization).
Build clear performance dashboards tied to CAC, LTV, conversion rates, payback, and retention.
Continuously optimize spend, channels, and messaging based on data and insights.
Brand & Integrated Marketing
Develop and steward a differentiated brand that builds trust with patients, caregivers, partners, and investors.
Lead integrated campaigns that connect performance channels with content, PR, partnerships, and storytelling.
Help position the company at the forefront of healthtech + AI, balancing credibility with accessibility.
Patient Experience & Lifecycle
Oversee the marketing components of the patient journey from first touch through activation and ongoing engagement.
Balance AI with human relationships to ensure patient communications are clear, empathetic, compliant, and effective.
Use qualitative and quantitative feedback to continuously improve patient experience and outcomes and leverage to inform continued development of core product
Ensure marketing reflects real patient needs, not just growth metrics.
Analytics & Strategy
Be the internal authority on marketing metrics, attribution, and insights.
Translate data into clear narratives and recommendations for executives and the board.
Define short- and long-term marketing strategy aligned with company growth stages (Series A → C+ and B2C → B2B).
Identify new growth opportunities, channels, and partnerships.
Leadership & Scale
Act as a player-coach: highly hands-on now, with a clear vision for building a world-class marketing team over time.
Hire and develop your team to reach ambitious and audacious objectives
What We’re Looking For
10+ years of marketing experience, with significant hands-on ownership in performance marketing and ideally one other core area of marketing (eg Content, Lifecycle, Brand, etc)
Experience leading or owning marketing at a healthtech or healthcare consumer company (AI-driven a big plus).
Deep fluency in marketing analytics, experimentation, and ROI-driven decision-making.
Demonstrated ability to balance brand and performance — you believe the best growth comes from both.
Strong understanding of patient or healthcare consumer journeys and trust-based marketing.
Comfortable operating in early-stage environments: scrappy, strategic, and execution-oriented.
Clear communicator who can influence across disciplines and levels.
Nice to Have
Experience marketing AI-enabled or data-driven healthcare products.
Familiarity with HIPAA, healthcare compliance, and regulated messaging.
Experience scaling marketing from Series A to IPO.
Why This Role Is Special
You’ll define marketing at a mission-driven company solving real problems for real patients.
You’ll have true ownership and executive visibility from day one.
You’ll shape not just growth, but how patients experience and trust our brand.
You’ll have a real seat at a table and partner closely with a Founder CEO who really gets it.
