Looking for feedback - job board with offers from product-based companies

Hi everyone!

I'm looking for feedback on the website I'm working on:
Get a Product Job - the job board with offers only from companies developing their own products.
https://getaproductjob.com/

Some info:

• It's my first Ruby on Rails website.
• I integrated EmailOctopus for email lists.
• It's possible to buy a job posting in presale.

Any feedback is highly appreciated: design, copy, or even about HTML code. Let me know what you think!

Thanks!
