About the Role
Our client is seeking a resourceful and self-driven Full Stack .NET Developer to support the development, integration, and maintenance of enterprise business applications.

The ideal candidate is curious, proactive, and comfortable investigating problems, asking questions, and taking initiative without relying on step-by-step direction.

What We're Looking For
The ideal candidate is more than a developer who writes code to specification. They are a proactive problem-solver who investigates why something is not working, asks thoughtful questions, and takes ownership of finding solutions. They are comfortable balancing development and integration work with business analysis and application support, and they can make progress in an environment where formal project management methodologies and step-by-step processes are not established.
