About us

💙 Implicity is a digital MedTech, that brings outstanding innovations to cardiologists, thanks to Big Data and Artificial Intelligence.

Thanks to our leading cardiac remote monitoring platform, it’s way easier to manage data and predict patient issues, so that cardiologists can bring the best care at the best time.

To put it simply, when you join Implicity, you’ll contribute to save lives with us 💓🩺

Dr Arnaud Rosier (cardiologist and AI researcher) & David Perlmutter (engineer and entrepreneur), co-founded Implicity in 2016.

• 10+ years later, a French Start-Up / Scale-Up 🐓 is a real game changer in the healthcare market, literally shaping the future of cardiology.
• 250+ hospitals / medical centers are already using our solutions, covering 100 000+ patients.

👩🏻👨🏿👱🏻 At Implicity, you will find the greatest experts in data science, engineering, clinical, regulatory, IT, sales, customers success, etc. working together.

This amazing team already managed to make Implicity a clear European leader, and we will very soon do the same in the US market.

In a nutshell, thanks to Implicity:

🏆 Patients get a far better care

🏆 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!

Job and recruitment context

We're hiring a Confirmed Software Engineer to join Workflow & Operations squad.

You are: A strategic backend engineer with a passion for building software that elegantly solves complex business problems. You believe that understanding the domain is key to good software design and have a proven ability to apply DDD and sound architectural principles. You are an excellent communicator, capable of explaining technical concepts clearly, and enjoy collaborating in a team environment.

⭐️ Build the Core Systems Driving Our Operational Excellence ⭐️

Are you a Senior Backend Engineer deeply passionate about building well-architected, scalable systems? Do you excel at 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.

🧁 Our Tech Stack

• Languages: TypeScript (primary), Python, Java
• Backend Frameworks: NestJS, Node.js
• Cloud Infrastructure & Containers: AWS, Docker, Kubernetes
• Databases: MongoDB, MariaDB, PostgreSQL
• Brokers: RabbitMQ
• CI / CD: GitLab CI
• Monitoring/Logging: Prometheus, Grafana, Datadog
• Testing: Jest
• Collaboration: JIRA, Notion

🥇 Background

• Master’s degree in Computer Science or equivalent significant practical experience.
• 4-7+ years of professional backend development experience, with a demonstrable focus on system design and architecture.
• Proven, hands-on experience applying Domain-Driven Design (DDD) principles in complex projects. Please be ready to discuss specific examples.
• Strong track record in designing, building, and maintaining scalable and resilient backend systems (microservices, event-driven architectures, or well-structured monoliths).
• Expertise in TypeScript and backend frameworks like NestJS (or similar Node.js frameworks like Express with a strong architectural understanding).
• Deep understanding of database design and modeling (both relational/SQL - PostgreSQL preferred, and NoSQL - MongoDB).
• Experience with cloud platforms (AWS preferred) and CI/CD practices (GitLab CI).

🥈 Your missions

• Participate in Backend Design: Spearhead the architectural design and technical implementation of backend services and APIs for the Workflow & Operations platform.
• Apply Domain-Driven Design: Champion and implement DDD principles (e.g., identifying Bounded Contexts, defining Aggregates, modeling Domain Events) to accurately represent complex administrative and operational workflows.
• Define Architecture: Design, evolve, and document the backend architecture (e.g., microservices, modular monoliths, event-driven patterns), making informed decisions based on domain needs and technical trade-offs.
• Develop Core Services: Build robust backend logic using TypeScript/NestJS for key functions like reporting data aggregation, financial process automation, and secure administrative data management.
• Collaborate & Translate: Work closely with Frontend Engineers, Product Managers, and internal stakeholders to understand requirements deeply and translate them into well-architected, domain-focused backend solutions.
• Ensure Quality & Best Practices: Drive high standards for code quality, comprehensive automated testing (unit, integration, domain logic tests), API design, security, and observability (monitoring, logging).
• Integrate Systems: Design and implement effective integration strategies with other internal and potentially external systems.

At Implicity, you will have a weekly meeting with your manager, to help you succeed in your mission, and continuously improve your skills.
Each team works with quarterly OKR, to be crystal clear, fair and honest with your targets.
The annual appraisal is a shared exchange moment, focused on your development.
