Growth Marketer - Data & Experimentation

A hands-on Growth Marketer role for someone who can move between analytics, experimentation, funnel design, campaign execution, and technical marketing infrastructure. This is a data-first, execution-heavy growth role for Tomorrow Bio, the fastest growing human cryopreservation company in the world.

What you'll do

• Own the growth funnel from acquisition to conversion: lead generation, landing pages, paid campaigns, email/WhatsApp flows, webinars, outbound, referrals, and other experiments.
• Design and run structured marketing experiments: define hypotheses, set up tests, measure results, and decide what to scale, change, or kill.
• Work directly with data: query databases, build dashboards, analyze funnels, cohorts, attribution, CAC/LTV, and conversion performance.
• Identify where prospects get stuck and translate that into better campaigns, messaging, segmentation, and sales handoffs.
• Create and ship campaigns for a highly analytical audience: founders, software engineers, investors, rationalists, scientists, biohackers, and longevity-curious high performers.
• Own and improve the growth stack: CRM, automation, attribution, dashboards, AI-assisted workflows, and campaign tooling.
• Work closely with the founder, sales, medical/scientific team, and engineering to turn insights into fast execution.

What you'll need

• Strong data and analytical skills; ability to query data yourself without relying on an analyst layer.
• Experience with funnel analysis, cohort analysis, attribution, CAC/LTV, conversion modeling, and dashboard building.
• Experience designing and evaluating A/B tests or other structured growth experiments.
• Comfortable using BI or analytics tools such as DataStudio, Metabase, Looker, Mixpanel, Amplitude, Tableau, or similar.
• Ability to ship campaigns yourself, not only brief agencies or wait for a team.
• Strong understanding of technical, rational, high-agency audiences; ideally close to the ICP in mindset or interests.
• Personal interest in longevity, biohacking, health-tech, biotech, AI, rationalism, or ambitious frontier technology.
• Excellent spoken and written English; based in Berlin (remote not possible).

Nice to have

• Experience in DTC, health-tech, longevity, biohacking, premium subscriptions, biotech, or high-innovation startups.
• German, French, or Italian.
• Python or R for analysis; familiarity with APIs, webhooks, Zapier, Make, n8n, or similar automation tools.
• A personal project, newsletter, podcast, community, or audience in longevity, rationalism, quantified self, startups, investing, or frontier technology.

What they offer

• Full ownership of growth at one of Europe's most ambitious life extension companies.
• Direct access to the founder and leadership team, with no unnecessary middle layer.
• High autonomy and fast decision-making.
• A complex, meaningful product with a highly unusual and intellectually serious audience.
