Senior Marketing Manager (Co-founder in B2C Health App)

About the Role 

ONU Health is building the AI-powered future of personal prevention. We unify medical, lifestyle, and wearable data into a single "health account," helping people see risks before they arise and take control of their wellbeing.

We're seeking a co-founding Marketing Manager who can bridge storytelling, community, and growth — turning a preventive health mission into a movement. You'll work closely with our designers and CEO to define how ONU Health is communicated, build our community, and grow our customer base.

Key Responsibilities

🧭 Brand Strategy & Positioning

• Define ONU's brand narrative — "Your data, your health, your prevention."
• Position ONU between medical credibility and lifestyle inspiration — where prevention feels aspirational, not clinical.
• Shape a unified messaging architecture across web, app, and social, highlighting ONU's unique value: predictive, data-driven, and privacy-first.
• Work with designers and the CEO to establish ONU's visual and verbal identity across all channels.

📊 Social Media, Funnels & Campaigns

• Own social media strategy and content calendar — building ONU's presence and voice across key platforms.
• Design and run campaigns that build brand awareness and drive customer acquisition.
• Build and optimize multi-channel acquisition funnels (content, influencer partnerships, paid social, and Apple Health integrations).
• Develop onboarding journeys, email/push automations, and retention loops tied to users' health improvements.
• Track activation, retention, and referral metrics to continuously refine messaging and campaign performance.

💬 Community & Thought Leadership

• Create the ONU Health Founding Member Program and early adopter community.
• Grow and nurture ONU's customer list and community channels.
• Collaborate with medical advisors and creators to launch educational campaigns around prevention and self-tracking.
• Drive storytelling across channels (press, social, product updates) to humanize complex AI health concepts.

Requirements

• Experience in social media, brand, or growth marketing, ideally in digital health, fitness, or consumer SaaS.
• Proven experience building campaigns and funnels that grow an audience or customer base, ideally for an early-stage product.
• Strong understanding of healthtech positioning, user psychology, and trust building (especially for sensitive data products).
• Analytical and creative mindset — fluent in both storytelling and metrics (CAC, LTV, retention).
• Comfortable working closely with designers and founders to shape brand identity from the ground up.
• Passion for preventive health, data-driven wellness, and AI-enabled personalization.

Benefits

• Equity: based on experience and time commitment, as a co-founding role.
• Vesting: 4 years with 1-year cliff.
• From February: Future Salary Post-funding (March 2026).
• Equal say in product and roadmap decisions alongside founders.
• Flexible schedule (20–30 hrs/week possible; past funding to full-time).
• Remote-first (EU time zones preferred).

ONU Health is a HealthTech startup from Berlin. We're building a smart "health account" — a secure platform for storing and analyzing medical data: test results, diagnoses, medications, and personal health goals. Using AI, we provide personalized recommendations and help people better understand their health. We are not a medical product and do not provide diagnoses.

Our team already includes four people — developers, designers, and a project manager. We're a close-knit, ambitious team building the future of preventive health.
