Project overview

Context and team

The team is small and agile. The developer works in direct and daily collaboration with the platform's Lead Engineer. The entity's mission is to design and industrialize internal applications and agents with high strategic impact, for C-Levels, CSR/Compliance departments, and group engineers.

Application portfolio:

Technical stack (monorepo)

Main missions

In a pair with the Lead Engineer, take charge of the end-to-end design and development of features across the entire stack.

Fullstack development and shared packages

Technical integrations and observability

Collaboration and proactive contribution
