Medical quality and governance

• Build and maintain the operational standards that protect medical quality as Lucis grows.
• Help define:
  • Clinical review and sign-off processes.
  • Quality-control systems.
  • Documentation standards.
  • Audit trails.
  • Escalation procedures.
  • Medical risk-management processes.
  • Clinical performance indicators.

Product and member experience

• Partner with Product and Design to ensure the clinical experience is accurate, clear, actionable, and trusted by members.
• Contribute to the medical logic behind:
  • Biomarker results.
  • Health-system interpretations.
  • Action plans.
  • AI coach interactions.
  • Member follow-up.
  • Preventive-health recommendations.

You may occasionally write or review clinical content, but your main responsibility is building the systems that make high-quality medical delivery repeatable.

Clinical research watch

• Keep Lucis up to date on developments across preventive medicine, longevity, functional medicine, and biomarker science.
• Identify relevant evidence, assess its quality, and help determine how it should influence our protocols, product, and clinical operations.

About You

You are a doctor who believes the future of medicine is preventive, personalised, scalable, and powered by AI.

You want your clinical expertise to reach millions of people, not only the patients you can see individually.

You enjoy creating structure in ambiguous environments. You are comfortable moving between clinical reasoning, operations, product, data, and technology.

You do not just identify medical problems. You build systems that prevent them from happening again.

You thrive in fast-moving environments, learn by doing, and treat feedback as a tool for continuous improvement.

You’ll fit in well if

• You hold an MD or equivalent medical degree.
• You have meaningful exposure to preventive medicine, longevity, functional medicine, or another relevant clinical field.
• You have strong clinical judgement and are comfortable working across multiple medical domains.
• You are highly organised and able to turn complex clinical knowledge into clear processes.
• You think in systems, workflows, and decision trees rather than one-off solutions.
• You are comfortable working with product, engineering, AI, operations, and design teams.
• You use AI tools daily and naturally.
• You are comfortable reviewing AI-generated clinical outputs.
• You can balance medical rigour with speed and pragmatism.
• You are proactive and take ownership beyond the boundaries of your role.
• You are fluent in French and English, both spoken and written.
• Spanish is a plus.

Experience in a startup, healthtech company, clinical operations team, or technology-enabled care environment is strongly valued.

We might not be a fit if

• You want to focus primarily on traditional clinical practice.
• You prefer working on individual cases rather than building scalable systems.
• You are uncomfortable making decisions in ambiguous environments.
• You expect every process and responsibility to already be clearly defined.
• You are uncomfortable with technology or prefer to avoid new tools.
• You do not want AI to be part of your daily workflow.
• You prefer to wait for instructions rather than proactively identifying problems.
• You have little interest in operations, processes, documentation, or quality systems.
• You prioritise predictable nine-to-five work over mission intensity.

How we work

We work together from our Paris hub.

We are deeply committed to what we are building and believe the fastest way to create something exceptional is to work side by side.

We can support relocation for the right person, and we welcome people based elsewhere in Europe who are willing to travel regularly to work with us in Paris.

Rigor without ego

Science, clinical operations, audits, and code all deserve the same high standard.

Radical ownership

Feedback loops are short, and everyone contributes beyond the boundaries of their job description to build the best possible version of Lucis.

Velocity over perfection

We ship every day and prefer a good decision today over a perfect decision next week.

AI-native by default

At Lucis, AI is not only our product; it is our operating engine.

Every team member has access to the best available AI tools and agents. You will have the freedom to explore, automate, and redesign workflows so that your time is spent on the highest-value work.
