We are looking for a Senior Backend Engineer with strong expertise in C#/.NET, cloud-native backend development, and API engineering.
This is a hands-on engineering role focused on building scalable, secure, and maintainable backend services in cloud environments. The engineer will work closely with Tech Leads and cross-functional teams to implement high-quality solutions aligned with established architectural and engineering standards.
