Join ACAI (Advanced Calendar Improvement) , a team dedicated to making day-to-day practice operations more efficient and less mentally exhausting for healthcare professionals and their teams.

Practice operations are often fragmented across post-its, emails, SMS, phone calls, oral instructions, and individual memory. This makes it difficult for teams to know what needs to be done, who owns it, how urgent it is, and what has already happened.

As a Software Engineer, you will help build products that centralise work, improve coordination, and automate administrative tasks across the practice; directly contributing to a smoother experience for healthcare professionals, staff, and patients.

Your responsibilities

Develop reliable, intuitive features for Task Manager, Patient Flow Management, patient intake, appointment proposals, and telesecretaryship workflows
Help practices coordinate the patient journey from arrival to completion of a visit, including waiting-room status, care steps, walk-ins, delays, patient movement, and check-out
Design solutions that reduce the time healthcare professionals and staff spend manually creating, sorting, remembering, relaunching, and completing tasks
Work across backend and frontend technologies to deliver high-quality, user-facing experiences
Build performant, reliable, and observable services that can support Doctolib's growing user base and complex healthcare workflows
Apply strong privacy, data protection, and security practices when working with personal and health-related information
Partner closely with Product, Design, Data Protection, and other engineering teams to understand problems and deliver valuable solutions

We leverage AI in an ethical manner across our products to empower patients and healthcare professionals. Discover our AI vision .
