Our client is looking for well-rounded developers to assist with security fixes (replacing 3rd party libraries, patching security issues) within their software.  This would not be considered a heavy security role, but they are doing security related patched and library upgrades etc.  It is a .net C# environment and they will be working on mainly windows platforms, but may have to jump on different systems as issues come in.  This person needs to be self sufficient and have the ability to pick things up on their own.  This is a great opportunity to join a global company on a contract to hire role that would be working on their flagship product.  



- Must have C# development experience.

- Must have experience fixing patches, replacing or upgrading third party libraries.

- Must have security patch fixing experience.

- working with embbeded software or embedded teams would be a plus
