one suggestion...you have some good qualifications. Rewrite them to show action and responsibility. Start sentences with words like Organized; Tested, Ensured, etc.
For example:
Led software testing and quality assurance efforts
Rewrite as:
Ensured quality compliance and tested software.
Rather than just describe the tasks, it shows your action and ownership of the task. In atough market, you need to show action and that you are a good investment.
Just a suggestion.
I will keep my ears open. Middle management jobs are tough now. Good luck.
