# Marketing Officer

**Leonar** · Paris, Île-de-France, France

Descriptif du poste

A disruptive HealthTech startup at the intersection of AI & high-precision hardware is looking for their Founding Marketer to lead their 2026 launch in the US and Europe.

The product is an innovation that could revolutionize the diagnosis of a certain type of disease.

The challenge

We are looking for a highly hands-on Founding Marketer to build and own our marketing from the ground up, working directly with the CEO.

This is a builder role: you will define our narrative and execute it across content, creative production and SEO.

Key Responsibilities Include

- Own and craft our narrative and tone of voice, across all channels
- Create, write and publish website pages, SEO-driven articles, LinkedIn content, and marketing materials
- Create high-quality visual and video assets
- Drive SEO and organic growth
Manage external contributors (video, design, PR) when needed while remaining the primary content creator

Profil recherché

It Could Be The Perfect Fit If You

- Are a true doer - you execute fast and autonomously
- Are a strong writer (this is critical)
- Have hands-on experience in content, growth, or product marketing, with a successful B2C, D2C or physician-facing product launch
- Have experience building or shaping a new category or narrative
- Have solid understanding of SEO fundamentals
- Are very comfortable creating content yourself
- Have a strong sense of neat aesthetics
- Have 5+ years of experience (we care more about what you’ve built than years)
- Are fluent in English - experience with the US market is strongly appreciated
Familiarity with medical/aesthetic healthcare is a nice-to-have though not mandatory

Our offer to you

We want every team member to have a stimulating environment for work and offer:

- A competitive package + stock options
- A great office in the center of Paris
- A warm and friendly work environment
Holiday bonus

Déroulement des entretiens

- Meeting with the CEO
- Case study
