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 Cardiac Device Monitoring squad.

Someone excited by complex technical challenges AND motivated by making a tangible impact in healthcare. You understand the gravity of working with sensitive patient data and strive for excellence in reliability and performance.

⭐️ Shape the Future of Cardiac Care with Data ⭐️

Are you passionate about building robust systems that handle critical, high-volume health data? Join our dedicated Cardiac Implantable Electronic Devices (CIED) team within a fast-growing healthcare scale-up! We're looking for skilled Software Engineers (Backend-focused or Full-stack with strong backend affinity) who thrive on tackling the challenges of data volume, velocity, variety, and veracity in a mission-critical environment.

You won't just be coding; you'll be at the heart of our MedTech mission, developing and scaling the platform that ingests, processes, and monitors data from thousands of life-sustaining cardiac devices. Your work directly contributes to better patient outcomes through reliable remote monitoring. This role requires a strong data-engineering mindset, even within our primarily web-oriented stack, and includes participation in a rotating on-call duty to ensure system availability.

🧁 Our Tech Stack Includes

• Languages: Typescript (primary), Python, Java
• Backend Frameworks: NestJS, Express
• Frontend: Angular, SASS
• Cloud Infrastructure & Containers: AWS (EC2, S3, RDS, etc.), Docker, Kubernetes
• Databases: MongoDB, MariaDB, PostgreSQL
• Brokers: RabbitMQ
• BigData/Querying Tools: (Exposure is a plus) Apache Spark, Apache Beam, Apache Flink, AWS Athena, AWS Glue
• Monitoring/Logging: Prometheus, Grafana, Datadog (or similar ELK stack components)
• CI/CD: GitLab CI
• Testing: Jest, Playwright
• Collaboration: JIRA, Notion

🥇 Background

• Master’s degree in Computer Science or equivalent practical experience.
  
• At least 3 years of experience in software development, ideally in environments handling significant data volumes or critical systems.
  
• Strong expertise in TypeScript and backend development.
  
• Solid experience with Node.js and associated frameworks (NestJS preferred).
  
• Proven experience designing and interacting with REST APIs.
  
• Experience with relational databases (PostgreSQL, MariaDB) and/or NoSQL databases (MongoDB).
  
• Familiarity with message brokers (e.g., RabbitMQ, Kafka) for asynchronous processing and data pipelines.
  
• Experience with cloud environments (AWS preferred) and CI/CD pipelines (e.g., GitLab CI).
  
• Demonstrable experience with monitoring and logging tools (Prometheus, Grafana, Datadog, or similar).

🥈 Your missions

You will:

• Design, develop, and maintain scalable backend APIs and data processing pipelines using TypeScript/NestJS to handle large streams of incoming CIED data.
• Build and enhance robust monitoring and alerting systems to ensure data integrity, system reliability, and timely issue detection across our critical infrastructure.
• Implement resilient, high-performance architectures capable of handling significant data loads and ensuring data accuracy, adhering to best practices for critical systems.
• Collaborate closely with clinical domain experts within the CIED team to understand data nuances and requirements.
• Ensure rigorous code quality, security (following OWASP Top 10), and compliance with MedTech industry standards (e.g., HIPAA, GDPR, medical device regulations) through comprehensive testing (unit, integration, end-to-end).
• Actively participate in the team's on-call rotation to support our production 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.
