Render your careers pages on the server side to support proper sharing on social networks and include the social meta tags.
The careers website is an opportunity to allow users and employees to share the company’s positions on social networks such as Facebook and LinkedIn. To maximize sharing, include meta tags in your html that include the position name, description and other information that should be available in the post. To enable social networks to read tags properly, the pages should be rendered on the server side—not on the client side.
See the list of meta tags suggested by Facebook – Facebook’s Content Sharing Best Practices.
