Lifecycle & CRM lead

Making preventive health the default for every human in Europe

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.

We're looking for a Lifecycle & CRM Lead to own everything that happens after a customer registers — activation, onboarding, engagement, retention, and referral. This is a zero-to-one role: no predecessor, no ceiling, and direct impact on the metric that matters most to our business.

Retention is acquisition. A 10% improvement in churn has the same P&L impact as acquiring 10% more customers at zero CAC. This role is that lever.

This individual contributor role is responsible for:

• Owning activation flows from registration through to paying customer

• Building and iterating onboarding sequences from purchase to first blood result received

• Running email and SMS strategy end-to-end — including writing the copy, not just designing the flows

• Defining customer segmentation logic and building behavioral personalization at scale

• Optimizing subscription renewals and repeat purchase rates

• Taking over and fixing our referral program (currently underperforming — this is yours to rebuild)

• Tracking and reporting on retention metrics, cohort analysis, NPS, and LTV attribution across all lifecycle programs

You're passionate about the future of human health and want your work to help people stay healthy for longer. You move quickly from idea to execution, take full ownership of what you build, and work best with talented people who care as much as you do.

You thrive in fast-moving environments, learn by doing, and treat feedback as fuel. You use AI the way others use a calculator: naturally, to go faster and think bigger.

You'll fit in well if you

• Have owned lifecycle or CRM end-to-end — not contributed to it, but built it, shipped it, and measured it yourself

• Can show retention or LTV improvement attached to your name, with actual numbers

• Are proficient with modern email and SMS platforms — Klaviyo, Braze, or Customer.io (we use Customer.io)

• Can write — subject lines, push copy, onboarding sequences. This is not a tool configuration role.

• Understand cohort analysis, incrementality measurement, and behavioral segmentation

• Are French or English native / near-native, with professional proficiency in the other

Nice to have

• Built a referral program from scratch

• Subscription or membership business background

• Experience in health, wellness, or DTC

• Multi-market lifecycle work (FR, UK, DE, BE or similar)

We might not be a fit if

• You need a clearly scoped role with stable responsibilities

• You've only contributed to lifecycle programs rather than owned them

• You prefer strategy over hands-on execution and copywriting

• You need perfect data before making decisions

• You're uncomfortable with fast iteration cycles and shifting priorities

What good looks like

• 30-day onboarding completion rate: 70%+

• Referral rate: <3% → 8%+ within 6 months

• 90-day churn: down 15% vs. baseline

• You can explain the LTV impact of every program you run

• Intro call (20 min): culture & role fit.

• Technical interview (30-60 min)

• At-home case study: hands-on project, delivery in 2 days.

• Deep dive and team chat, on-site (1.5 - 3 hours)

• Reference calls

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.
