Medical Excellence

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 operating system for human longevity to help people add more healthy years to their lives.

The role

Lucis analyses more than 110 biomarkers, builds personalised clinical protocols, and delivers them through an AI-powered preventive health product.

As Medical Excellence, you are the senior medical expert next to product and Medical ops. You bring deep clinical expertise into protocols, ranges, evidence, and what we can say next to a marker. You also cover medical content: biomarker copy, protocols, and marketing clinical sign-off.

You work with the product lead, Medical ops, medical reviewers, and AI. You do not own product decisions, and you do not own labs, partners, or turnaround — Medical ops does.

This is not a traditional bedside role. It is not an ops role. It is not a copywriting role. You have practiced medicine in depth, and you can turn clinical judgment into clear protocols, ranges, and member-facing language.

What you own

Protocols & clinical standards

Protocol logic, decision trees, clinical rules

Biomarker thresholds and expert ranges

Translate medical reasoning into structures the product and Medical ops can run

Keep protocols aligned with current evidence

Support new biomarkers, health systems, and preventive programmes from the clinical side

Evidence & clinical judgment

Evidence bar: what we should test, drop, or claim

Brief product and the team without a 40-page memo

Clinical review of edge cases and sensitive outputs

Review of AI-generated medical outputs for clinical accuracy and safety

Medical content

Biomarker explanations, protocol rationales, in-product clinical language

Coach / member-facing clinical copy

Marketing clinical sign-off

French and English at publication quality

Keep member-facing clinical language trustworthy

Medical quality and governance

Clinical review and sign-off processes (clinical side: what must be medically signed off, and to what standard)

Quality-control systems, documentation standards, audit trails — in partnership with Medical ops

Escalation and medical risk-management processes — clinical criteria and judgment

Clinical performance indicators — definition of medical quality bars, with Medical ops on measurement and ops

About you

You are a doctor with substantial clinical practice. You care that what members read and what protocols encode is medically sound. You are comfortable working with product and AI without needing to run either. You write like a clinician people would trust.

You’ll fit in well if

You hold an MD (preferred) with deep clinical practice — more experience than a junior reviewer

Prevention, internal medicine, nutrition, functional, cardiology, public health, or a related field is a plus

You have strong clinical judgement, case by case and when defining standards

You can set protocol logic, ranges, and an evidence bar other people can execute

You write clearly in French and English at publication quality

You work well with product, Medical ops, AI, and reviewers — without owning their roadmaps

You balance medical rigour with pragmatism

You take ownership beyond a narrow specialty lane

We might not be a fit if

You want to focus primarily on traditional bedside practice

You want to run labs, partners, turnaround, or ops queues (that’s Medical ops)

You want to own the product roadmap

You prefer pure research or citation work without shipping clinical standards

You are a copywriter without real clinical practice

You need every process already defined before you contribute

You prioritise predictable nine-to-five work over mission intensity
