What they're building

AI-assisted B2C customer care and support operations moderate signal

Today: "Lucis is your health companion, helping you deeply understand your biology and take action to improve it." (site)

Roles: Customer Care Specialist · Customer Care Team Lead

Requirements mention: AI automation · automating repetitive workflows with AI · high-volume B2C customer care or support · AI agents · internal OS

Inference: a two-role care build that asks for AI automation and an internal OS suggests the care workflow is being run with AI tools, though the postings do not describe the tools in detail.

Clinical review, medical operations and governance for personalised protocols strong signal

Today: "110+ data points, 11 body systems, 450+ labs in Europe" and "Lucis helps doctors surface risks early" (site)

Roles: Medical Director · Medical Ops Lead · Doctors - open applications

Requirements mention: medical review queue · clinical protocols · SLAs · turnaround times · quality-control systems · medical device classification · medical safety system · Can defend a recommendation against the evidence, in writing

Inference: a director, an ops lead and open clinician applications, with review-queue and SLA requirements, suggest a clinical review layer is being staffed around the protocol product. The Medical Director posting also asks for medical device classification and a governance model, and states the product is 'currently live in France and opening in the UK, Portugal and Spain'.

Internal AI adoption across functions strong signal

Today: "We bring together experts in health sciences, data, and technology." (site)

Roles: CTO right-hand · EA / workplace manager · Customer Care Team Lead · Platform engineering · Doctors - open applications

Requirements mention: technical enablement · drive adoption · AI agents · Claude Code · Cursor · Use AI in your daily work

Inference: AI tool use is asked for in engineering, clinical, care and admin roles, and one role is dedicated to driving adoption, which suggests everyday use of AI tools is expected in most jobs here.

AI agents for preventive health analysis weak signal

Today: "Our report focuses on key biomarkers for your health" (site)

Roles: AI engineer

Requirements mention: AI agents · retrieval pipelines · RAG architecture · evals · clinical citation

No inference drawn beyond the posting's own description, which says the agents 'act as a doctor for preventive health, analyzing 110+ biomarkers and delivering protocols'; this is one posting.

Mobile app frontend weak signal

Today: "Discover my health profile" (site button)

Roles: Mobile frontend engineering

Requirements mention: Expo · React Native · native experience

No inference drawn; one posting is not enough to read a build direction.

Core platform commerce: payments, checkout and subscriptions weak signal

Today: "From €490/year." (site)

Roles: Core platform growth engineering

Requirements mention: payments · checkout · subscriptions · promotions · partner offers

No inference drawn; one posting is not enough to read a build direction.

Where the headcount is going

DepartmentOpen
Product & tech6
Clinical3
Operations2
G&A2

Nearly half of the 13 openings are Product & tech (6), with a three-role clinical team next. Operations and G&A have 2 each, so the hiring centres on building the product and staffing its medical review.

Who they need

Seniority: 6 senior, 3 mid, 2 junior, 1 manager and 1 unknown.

Skills named most: TypeScript, Next.js, NestJS, PostgreSQL, Prisma, AWS, Terraform, GitHub Actions, React Native, Python, Claude Code / AI agents, English and French

Locations: All 13 postings list Paris; 8 are marked remote and the postings do not state a country for remote work. One posting says the product is opening in the UK, Portugal and Spain, but no roles are listed there.

How to use this

If you're applying: Check the Paris location and the hard requirements in each posting before applying: English and French for the care roles, Expo and React Native for mobile, and an MD, clinical qualification or life sciences degree for the doctor posting. Expect to be asked how you use AI tools, since most postings require them.

If you're selling or recruiting: Product & tech is the largest group with 6 roles; Clinical is next with 3, led by a Medical Director and Medical Ops Lead whose postings cover review queues, SLAs and medical device classification. One posting says the product is live in France and opening in the UK, Portugal and Spain. The postings do not name a buyer or budget, so confirm scope on the call.
