We build with intent, focusing on solving real problems that matter. In a regulated environment, compliance, security, and resilience are at our core. We value ownership, open collaboration, and a shared vocabulary to keep complexity manageable. Simplicity is key, clean, maintainable code wins over clever tricks. We ship fast, learn continuously, and always strive for excellence. 💡

Your mission

• You will be technically responsible for one or more projects.

• You will have the opportunity to solve problems in one of the most demanding IT domains with a reactive architecture.

• You will design with the product team the bank by API.

• You will improve the performance of a system with a rapidly growing load.

• You will ensure the respect of the architecture rules and of the automated tests

Our technical environment

• Java/Scala, Node.js/TypeScript, GraphQL, PostgreSQL, Redis, Kafka, Kubernetes, AWS/GCP
