Build the Core Systems Driving Our Operational Excellence

Are you a Confirmed Backend Engineer deeply passionate about building well-architected, scalable systems? Are you experiencedat modeling complex business domains and translating them into robust, maintainable code? Join our dedicated Workflow & Operations (Admin) team, based entirely in our Paris office!

Our team's mission is vital: we build the critical remote monitoring platforms that streamline operations and enable clinics and practices to scale and function efficiently. This includes systems for operational reporting, financial management support, administrative patient information, and core platform navigation. These systems are complex and essential.

We're seeking an experienced Backend Engineer with a strong architectural mindset to take a major role in designing and building these systems. You will have the opportunity to apply DDD principles to effectively model our operational domains and define a backend architecture that ensures long-term scalability, maintainability, and resilience.

• You enjoy working in a fast-paced and ever-changing environment
• Strong work ethic & daily act with integrity, honesty and fairness
• Definitely a thoughtful team player, looking to make your colleagues successful

Doctors' life is far easier, they can have a far better focus on prevention/treatment, and not admin/data burden

Healthcare payers (Social Security in France) eventually pays a far lower price (preventing/monitoring instead of treating/hospitalizing)

It can start as soon as you can!
