Participation in Agile team rituals.
Contribution to the team's rotating support role.
Occasional travel to Paris will be required for training, coordination with development partners, and meetings with end users.
Profile
Confirmed experience in .NET development (7–10 years).
Expertise in real-time environments and multi-threading challenges.
