LIASON: Serves as organization spokesperson on advanced projects and/or programs. Acts as advisor to management and customers on advanced technical research studies and applications.

The core functional role is to enable the effective testing of end products by providing design, development, and maintenance support for various manual and automated testing hardware and software infrastructure.

• Maintain existing hardware-in-the-loop test systems by addressing new and existing issues, and providing functional support in how to use and configure these systems to achieve desired testing goals.
• Refactor existing systems to provide more useable, stable, maintainable, and/or efficient functionality.
• Develop new software and hardware components to add capabilities to systems which support new testing requirements.
• Develop internal hardware and software tools to improve the productivity of and/or ease of execution of testing tasks.
• Assist other functional groups in use of testing tools and provide limited domain area expertise outside of immediate test infrastructure support duties.
• Provide guidance and mentorship to less experienced engineers
