Who's hiring in your field?
Mathworks themselves. They're a big sponsor of public radio in my area, announcing plenty of job openings.
They have done a good job developing an "ecosystem" around their core products. There are many companies selling addons. Look here. https://www.mathworks.com/products/connections/search-services.html?q=&page=1 .
Maybe you work with one or more of these addon products. At any rate you can use this list of addon providers as prospective employers.
Mathworks runs trade shows all over the world. http://www.matlabexpo.com/ Print up a bunch of business cards saying you're looking for work and giving your contact information, and print up some resumes / CVs. Go to one of the trade shows and talk to everybody. Ask people, "What do you do?" and "Do you know anybody who's hiring?"
Believe me, these questions aren't rude or a sign of weakness. Not at all. People want to make connections and help other people get started in a specialized field.
You're looking for work at a good time. Many employers have openings.
