SUMMARY

The Senior .NET Developer is a senior individual contributor who leads software projects from requirements through deployment and support. You’ll work directly with business stakeholders to turn their needs into technical solutions, and design, build and maintain applications using Angular, C#/.NET, REST APIs and Microsoft SQL Server.

You’ll combine hands-on development with project ownership: clarifying requirements, estimating work, coordinating delivery, communicating progress and risks, and ensuring quality. You’ll make application-level design decisions within engineering standards and partner with the Software Development Manager on architecture and priorities.
