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 a strategic, proactive EA / workplace manager to amplify our founders impact and make Lucis run seamlessly. You will watch their back.
You’ll be the operational backbone of our Paris HQ, orchestrating founder logistics, shaping the company rhythm, and enabling the team to scale fast and smoothly.
You'll scale faster than the founders, and will grow faster than the company.
What you'll own
Founder velocity: Owning the complex, multi-time-zone calendars and travel logistics to ensure the founders are always in the right place at the right time with the right information.
Assisting the founders in their day-to-day important events: board meetings, client meetings, and co. You'll help founders be on top of their game.
Inbox & communication: Triaging high-volume inboxes and ensuring 100% accountability on follow-ups with partners, investors, and the ecosystem.
The Paris hub: Managing our physical HQ end-to-end: from vendor relationships to hosting VIPs.
Operational rigour: Handling invoice payments, accounting workflows, and HR admin (employee requests and office onboarding).
Culture infrastructure: Designing and executing the logistics for team events and marketing pop-ups as we expand across Europe.
Founder proxy: Acting as the first point of contact for the team and external stakeholders, protecting the founders' deep work time while ensuring the team has what it needs.
About you
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 value feedback as a way to continuously improve. You're curious about AI and how it can be used to move faster and think bigger.
You’ll fit in well if you
1 to 3+ years in a challenging / fast-growing environment (Series A/B preferred) or a rigorous professional services environment (law, finance, or consulting).
Fluent in English and in French.
Take radical ownership and default to action: You anticipate needs before they are voiced and ensure that once a task is started, the loop is closed every single time.
You’re used to fast change and context-switching: You can jump from complex multi-time-zone calendar management to fixing an office infrastructure issue without losing momentum.
You're very comfortable using AI, and learn super fast.
You're willing to take anything that has to be done. Anytime, anywhere. No matter how fun that is.
You can act as a high-level gatekeeper and founder proxy: You are comfortable hosting investors, partners and protecting the founders' time for 10x deep work.
You bring extreme rigor to operational admin: Experienced in handling invoice payments, expense tracking, and basic HR/onboarding workflows.
You’re strong at stakeholder management and culture-building: You take pride in building a world-class environment in the Paris HQ for both local and visiting remote employees.
We might not be a fit if
You need a clearly defined role with stable responsibilities.
You prefer strategic advisory work over hands-on execution.
You've only worked in large, well-established companies.
You need perfect information before making decisions.
You prioritise predictable 9-5 work over mission intensity.
You're uncomfortable with frequent context-switching and urgent pivots.
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.
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.
