About the role

Making preventive health the default for every human in Europe

The mission

At Lucis, we believe healthcare should be preventive, not reactive. We’re building the OS for human longevity to help people add more healthy years to their lives. You can read more about who we are and how we work here.

The role

We're looking for someone to own all new paid customer acquisition — the person who turns our brand into growth.

What you'll own:

  • All paid channels: Meta, Google, TikTok, YouTube, programmatic
  • Performance creative strategy and testing infrastructure
  • CAC optimisation across France, UK, Germany, and Spain
  • Attribution and acquisition analytics
  • Referral program growth (with Lifecycle Lead)
  • First media buying hire (within 6 months)

What good looks like in 6 months:

  • Monthly paid spend scaled from €50K → €150K+ at CAC ≤ €85
  • UK market launched on paid (May 2026) at CAC ≤ €90
  • Creative testing engine running: 20+ new creatives/month, sub-48h launch velocity
  • Attribution framework that actually reflects cross-channel reality

What we're looking for:

  • You've personally managed at least €100K+/month in paid media (Meta + Google minimum)
  • You've scaled DTC or subscription acquisition in Europe — you know what works here, not just in the US
  • You can build dashboards and work directly in ad platforms — strategy without execution doesn't cut it here
  • You think in CAC/LTV math, not reach and impressions
  • You're a player-coach: you can build the playbook and run the plays yourself

Nice to have:

  • Health, wellness, or regulated consumer experience
  • Multi-market EU scaling (FR, UK, DE, ES)
  • Experience using UGC/influencer content in paid
  • Familiarity with attribution tools: Triple Whale, Northbeam, Adjust, AppsFlyer

Why Lucis:

  • Full ownership of acquisition from day one
  • Direct line to the CEO
  • €50K → €400K+ monthly spend trajectory in 18 months
  • Building something that genuinely matters — preventive health for everyone

How we work

We work together from our Paris hub. We’re passionate about what we’re building and believe the fastest way to create something exceptional is side by side. We’re open to relocation support for the right individuals, and we welcome missionaries who travel to work with us in Paris on a regular basis.

  • Rigor without ego: Audits, science, and code all deserve the same high bar.
  • Radical ownership: Feedback loops are short; everyone contributes to building the best version of Lucis.
  • Velocity over perfection: We ship daily and prefer a good decision today over a perfect one next week.

At Lucis, AI isn't just our product, it's our engine. 100% of our teams are equipped with the best AI agents. You have carte blanche to explore and automate everything that can be, so you can focus exclusively on high-value work.
