Looking for a recruitment platform I can integrate with SqSp

My client wants prospective employees to be able to apply for jobs on her site. I would typically use a blog + summary block to list the jobs themselves. I'd like to present her with the option of

1) the applicant uploads their CV/resume via a form and Dropbox and recruitment is handled manually, as she currently does or

2) the applicant clicks the 'Apply' button on the job vacancy, and it links to a recruitment portal where they can track their application and the client can manage vacancies and applications etc. 

I am aware of Greenhouse and BambooHR etc but I cannot find if these can be embedded into SqSp. If not, would it just be a case of linking the 'Apply' button to the recruitment platform's native application page? If not, what is the best way for applicants to apply for jobs?

I think (2) would be better, but I don't see any can embed into SQSP, you can post on some groups on Facebook to ask this.

With (1), you can create a Form in Not Linked, use SQSP Uploader Plugin to create an upload file to form, then use Section Loader Supreme Plugin, to make this form appears on all blog post, So you won't need to manually insert the form into each post.

We can also use code to make so that the form will identify where it is (autofill Blog Post Title into Form Field), so that when submissions are sent to email, it will also display the job name that the person submitted
