we have created at The Construct a page that lists ROS Developers for hiring containing their skills in the field.
The page can be used by ROS Developers to be hired, or by employers to hire a ROS Developer.
It doesn’t require the creation of any account in order to search and contact a ROS Developer. It is also free of charge for both developers and employers.
The page can be found here
If you want to be included in the page as a ROS developer for hiring, follow the instructions of this video.
I hope this helps!
