Role

Who you are

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

Desirable

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

What the job involves

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 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

Application process

First contact with Astrid (Talent Acquisition) — 30-45 min - Remote
Fit & vision interview with Louay (CTO) — 45 min - Remote
Technical interview with members of the squad — 1h30-2h - On-site

Reference check & offer
Depending on your availability, the recruitment process should last less than 3-4 weeks

Our take

The MedTech boom has seen many innovations through the 2010s, and Implicity, a remote patient monitoring and cardiac data management company, has definitely had a clear lineage of growth since its founding in 2016.

Implicity develops software to monitor and analyze the information from pacemakers and cardiovascular devices to aid physicians and healthcare professionals through all stages of a patient’s treatment. However, maintaining growth on one product alone is hard, especially with so much MedTech competition. Implicity remedies this with its other product, a data analysis platform that uses AI and cloud technology to analyze the devices linked up to its aforementioned pacemaker and cardio health platform. Implicity leverages this data for use in patient management, clinical studies, and R&D.

Playing both fields of MedTech has diversified the draw for hospitals and companies to Implicity. It continues to update and diversify the double offering via updates to its systems with the company hoping to exemplify the continued innovation that is key to MedTech company growth.
