First step

Network smartly: ex-bosses, colleagues, headhunters, and social media; target valued organizations.

Reach out to,

Your ex-bosses who are currently in a position of authority and who you think will value your experience.
Friends / ex-colleagues in other organizations.
Headhunters.
Other networking including on social media.

In that order of preference.

Prepare a list of organizations who you feel will appreciate your experience and will consider you to be of value to their business
