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.
Be the CEO's strategic right hand — the force multiplier that turns ambiguity into execution. Own critical cross-functional projects, build scalable systems, and interface with investors/partners on behalf of the CEO.
What you'll own (first 6 months)
Drafting monthly investor updates and maintain investor CRM
Coordinating board materials and follow-up action items
Leading international expansion prep (UK, Portugal, Spain)
Building systems and dashboards for CEO visibility
Running weekly leadership syncs with department heads
You'll fit in well if
You have 3–5 years in high-growth startups, strategy consulting, or investment banking
You've worked directly with founders or C-level executives in fast-paced environment
You're a master of execution: builds financial models, writes crisp decks, ships projects end-to-end
You're a SaaS tool power user: Notion, Airtable, Figma, Raycast, AI tools (ChatGPT, Claude)
You're a spreadsheet wizard: Advanced Excel/Google Sheets (pivot tables, formulas, dashboards)
You're an exceptional writer: Can draft investor memos, board materials, strategic docs
You're fluent in English + French (critical for FR/UK/PT markets)
We might not be a fit if
You need clearly defined role with stable responsibilities
You prefer "strategic advisory" work over hands-on execution
You've only worked in large, well-established companies (Series C+)
You need perfect information before making decisions
You're looking for work-life balance over mission intensity
You're uncomfortable with frequent context-switching and urgent pivots
What excites you
Ambiguity → Clarity: Thrives turning messy, undefined problems into structured plans
Resourcefulness: Finds creative solutions with limited resources and tight timelines
Extreme ownership: Takes full responsibility for outcomes, no excuses
Builder mindset: Ships 80% perfect today vs. 100% perfect next month
Intellectual curiosity: Dives deep into new domains (health regulation, lab logistics, fintech)
Mission-driven: Cares about preventive health, longevity, helping people live better
What great looks like
Track record of shipping complex cross-functional projects
Expert in productivity tools and financial modeling
Exceptional written communication for investor/board materials
Direct experience working with founders in 0→1 environments
Bilingual EN/FR with European market context
