Senior Software Engineer

What you'll do

We are looking for a Senior Java/Kotlin Software Engineer to join the Doctolib's Platform team, NTC, who's in charge of the async platform and communication APIs for Doctolib.

NTC is part of the Platform domain, whose mission is to build and maintain the common building blocks of our system with a "Platform as a Product" mindset. We abstract and simplify the use of these complex, critical services, enabling product teams to focus on their core mission: building products faster for healthcare professionals and patients.

NTC (Notification & Task Control) is responsible for two critical systems: a communication platform that reliably delivers millions of messages across multiple channels (SMS, email, push notifications), and an async processing platform that orchestrates all background tasks across the company. All Doctolib product teams leverage the services we provide to accelerate development while ensuring the highest standards of quality, compliance, and security.

• Take a leading role within the team and contribute to establishing a technical vision that ensures the performance, security, and usability of the application, taking into account the future needs and the high scalability needs.
• Bring your expertise and experiences to help us continuously improve the way we design, implement, test, and monitor high-quality features
• Improving the performance of key features implemented in Java/Kotlin and spring boot
• Taking leadership on delivering roadmap items (together with the team)
• Contributing to establishing a technical vision and co-drive the creation of the roadmap for next quarters
• Providing help and advice to other teams as a Platform expert and co-building some of the solutions with them

About our tech environment

• Our solutions are built on a single fully cloud-native platform that supports web and mobile app interfaces, multiple languages, and is adapted to the country and healthcare specialty requirements. To address these challenges, we are modularizing our platform run in a distributed architecture through reusable components.
• Our platform processes millions of background jobs daily and delivers millions of communications across Europe.
• Our stack is composed of Java, Kotlin, Spring boot, Kafka, Rails, Redis & PostgreSQL.
• We leverage AI in an ethical manner across our products to empower patients and health professionals. Discover our AI vision here and learn about our first AI hackathon here
