Backend Engineer Implicity Is Hiring H/F

Les missions du poste

About

Artificial Intelligence & Big Data lead to paramount progresses in Healthcare, and Implicity has a leading position to shape the future of Cardiology.

Implicity created a SaaS cloud-based & AI-driven platform, that automates the cardiac remote monitoring of:

- Implanted devices, like pacemakers, defibrillators, etc.
- External devices, like weight scales for instance

Implicity remote monitoring platform was designed by Dr Arnaud Rosier, cardiologist, to provide hospitals with a complete solution to effectively monitor their patients.
Medical teams can now have a far better focus on prevention/treatment, bringing the best care at the best time, instead of struggling in admin/data burden.

No other company in the world is able to compete with their:

- Exhaustive real-time data collection / aggregation across vendors
- UX design
- Powerful algorithms, that bring the greatest support to cardiologists for diagnostics

The predictive algorithm brings a preventive dimension to the monitoring of cardiac rhythm diseases, heart failure and other cardiovascular diseases.
And by avoiding hospitalization, Implicity meets the challenges of healthcare costs control.

To put in a nutshell, Implicity saves thousands of lives at a lesser cost...



Job Description

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 liveswith 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

Opening line

We are looking for a Backend Engineer to join our Ingestion squad, with solid TypeScript skills.

This is a backend engineering role serving a data domain. You will build the services, connectors and orchestration that bring cardiac device data into our platform.

These services sit on a clinically critical path: the reliability of what you build has a direct impact on patient monitoring, and everything runs in a regulated HealthTech environment (HDS hosting, medical-device traceability).

Reporting Structure

Direct Report: Julien Sarazin (Deputy CTO)

Collaboration: Data Ingestion Squad

Your missions

- Develop and maintain the backend services of our ingestion platform (TypeScript, NestJS, Node.js)
- Build and evolve the connectors that integrate data from implanted and ambulatory cardiac devices - pacemakers, defibrillators, monitors - into the platform
- Orchestrate processing with Temporal, and handle service-to-service communication (RabbitMQ)
- Design and expose the APIs consumed by the rest of the platform
- Optimise access to our PostgreSQL, MariaDB and MongoDB databases
- Own reliability in production: Grafana, GitLab CI, deployment on Kubernetes and AWS

Our Technical Environment

Our stack is currently evolving. We do not expect expertise on every tool.

- Cloud & containers: AWS, Docker, Kubernetes
- Languages: TypeScript (primary), Python
- Backend: NestJS, Node.js - Architecture: microservices, event-driven
- Ingestion & orchestration: Transitioning to Temporal
- Databases: PostgreSQL, MariaDB, MongoDB, BigQuery
- CI/CD: GitLab CI - Testing: Jest, Xray
- Observability: Grafana, Prometheus, Datadog
- Collaboration: JIRA, Notion

Your profile

Must have:

- 3+ years of experience in backend development, including taking services to production and operating them over time: deployment, monitoring, alerting, incident management
- Strong backend engineering skills in at least one of: Python, TypeScript/Node.js, Java, Go or Scala. The squad works primarily in TypeScript and Python.
- Experience designing APIs and integrating data from external sources
- Good understanding of SQL and NoSQL databases, and an interest in query optimisation
- Fluency in both English (essential for team collaboration) and French (for local interaction) is required
- Curiosity and AI usage: We actively embrace working with AI productivity tools such as Claude to solve problems, sharpen code quality, and maximize efficiency. Fully leveraging AI in our daily work is not just encouraged - it's an essential strength we cultivate.

Nice to have:

- Docker and Kubernetes
- Workflow orchestration or message brokers (Temporal, Dagster, Kafka)
- Experience in a regulated environment (health data, finance, public sector), or the habit of designing services with traceability and audit trails - knowing what was processed, when, and by which version of the service
- Knowledge of Avro, Parquet or Protobuf
- Already practiced TDD
- Open source project development experience

A note on applying: we know the perfect candidate doesn't exist. If you believe you possess the core required experience and strongly align with this mindset, we highly encourage you to apply.

Recruitment process
- First contact with Astrid (Talent Acquisition) - 30-45 min - Remote
