SEO optimisation for the Jobs page

The current jobs page on the site isn't going to generate a decent search listing and isn't going to beat the authority of jobs.theguardian.com. I've worked with the Audience team to make some changes that should make the page rank higher for people searching for development jobs and also to try and create a decent search listing for the page.

These changes are optimal for search but don't follow some of the conventions for the other pages, I think that's okay as this page has a specific job to do. However if it needs to be consistent then I would SEO the whole site rather than keep the current format.
Capitalise heading to follow convention in other places.
