Job and recruitment context

We're hiring a Senior Backend Software Engineer to join Heart Failure Monitoring squad.

A highly motivated and autonomous Senior Backend Engineer with a proven track record in production environments. You possess a strong sense of ownership, are meticulous about security and compliance (especially GDPR), and excel at communicating across geographical boundaries. You see the value in robust deployment practices and are comfortable being the go-to technical person on the ground.

⭐️ Become a Pivotal Player in Transforming Heart Failure Care ⭐️

Are you an experienced Backend Software Engineer with a passion for building robust systems AND ensuring they run flawlessly in production? Do you thrive in bridging technical teams and safeguarding critical data? Join our dedicated Heart Failure team as the technical anchor in our Paris office!

Our company is at the forefront of MedTech innovation, developing remote monitoring solutions that make a real difference. The Heart Failure team is central to this mission, managing complex data streams to provide timely insights for clinicians. While most of our talented engineering team collaborates remotely from overseas, our Product Manager is based with you in Paris.

We're looking for a Backend Engineer to not only contribute significantly to the design and development of our platform (using TypeScript/NestJS on AWS) but also to take a major role in deploying and maintaining our production systems. As our key technical presence in Paris, you will be instrumental in enabling secure data access for the remote team in strict compliance with GDPR and EU regulations, acting as a vital bridge and local point of expertise. This is a unique opportunity to blend deep technical contribution with crucial operational responsibility.

🧁 Our Tech Stack Includes

• Cloud Infrastructure & Containers: AWS, Docker, Kubernetes
• Languages: Typescript (primary), Python, Java
• Backend: NestJS, Node.js
• Databases: MongoDB, MariaDB, PostgreSQL

🥇 Background

• Master’s degree in Computer Science or equivalent relevant experience.
• 5+ years of experience in backend software development, with significant time spent working on systems in production.
• Strong expertise in TypeScript and modern backend frameworks (NestJS preferred, Node.js/Express acceptable).
• Demonstrable, hands-on experience designing, building, and managing CI/CD pipelines (GitLab CI is a strong plus).
• Proven experience deploying, monitoring, and managing applications in a cloud environment (AWS strongly preferred) using Docker and Kubernetes.
• Solid experience with relational databases (PostgreSQL, MariaDB) and/or NoSQL databases (MongoDB).
• Experience with message brokers (RabbitMQ, Kafka) is beneficial.

🥈 Your missions

Your Impact & Key Missions:

• Develop & Architect: In collaboration with your Technical lead, design, build, test, and maintain scalable, high-performance backend APIs and services for the Heart Failure data platform using TypeScript/NestJS.
• Own Deployments: Take ownership of and continuously improve the CI/CD pipelines (GitLab CI) for the Heart Failure backend services, ensuring smooth, reliable, and frequent deployments to our AWS production environment (using Docker & Kubernetes).
• Ensure Production Stability: Monitor system health (Prometheus, Grafana, Datadog), troubleshoot production issues, manage incident responses, and participate in an on-call rotation.
• Safeguard Sensitive Data: Implement, manage, and potentially execute secure processes for accessing and handling sensitive EU patient data, ensuring strict adherence to GDPR and internal data governance policies, often acting as the local gateway for the overseas team.
• Bridge Teams: Serve as the primary technical liaison in Paris, collaborating closely with the overseas engineering team, the local Product Manager, and potentially other Paris-based stakeholders. Facilitate communication and provide local technical support/context when needed.
• Champion Best Practices: Drive high standards for code quality, testing, security (OWASP), and documentation within the team.

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.
