Founding Growth Marketer (m/f/d)
On-siteHamburg, Hamburg, Germany
Job Summary
Own growth and paid acquisition end to end, from first impression to booked demo. Push SEO and GEO further while extending lead as AI search evolves. Manage paid campaigns across Google, LinkedIn, and Meta, handling setup, targeting, budget allocation, and daily optimization. Run continuous growth experiments by forming hypotheses, shipping tests, analyzing data, and iterating. A/B test landing pages relentlessly to find high-converting messaging. Own the creative pipeline by briefing shoots and producing assets. Manage marketing analytics and reporting end to end, including attribution, CAC, and pipeline contribution. Feed every signal back to the founding team regarding messaging, channels, and verticals. This role builds the acquisition and experimentation engine for the A11 Ecosystem, a next-generation procurement platform redefining European public tenders.
Required Qualifications
- Hands-on experience running paid B2B campaigns across Google, LinkedIn, and/or Meta, with real budget and accountability for results, ideally in B2B SaaS
- A real growth-experimentation mindset: you've run structured tests, not just one-off campaigns
- You live in the numbers: you can build the attribution model and read it, not just admire someone else's dashboard
- A strong understanding of SEO and GEO, and the instinct to keep improving an already strong position
- Full-funnel instinct: you think about the landing page, the messaging, and the demo, not just the click
- Comfortable directing creative: you can brief a shoot and judge what makes a good ad
- Comfortable building automated, AI-first workflows with tools like Claude Code, n8n, and similar
- Clear, confident communication in German, plus strong English
- Please note that this position is based in Hamburg.
Desired Qualifications
- Are the kind of person who figures things out before asking for help
- Get a kick out of watching a CAC curve bend the right way because of something you shipped
- Want to build a marketing engine from scratch, not inherit someone else's dashboard
- Are hungry for ownership and not interested in waiting for permission
- Care about results but stay humble about what you don't know yet
- Have something outside of work that shows you don't do things halfway, whether that's competitive sports, a side project, or something completely different
- See this as the launchpad for a career as a growth leader or building your own thing
