Devise nested attributes form field not showing

I am having trouble viewing the nested attributes field in my form. I am in the jobs/new view and I want have a User form that creates a job as well as a user.

I have everything in this answer Rails 4.0 with Devise. Nested attributes Unpermited parameters

I have also checked out this Nested attributes not showing up in simple form

But the latter answer already applies to my code and it is not showing up. My Code:

Job Model

belongs_to :user

User Model

has_many :jobs
accepts_nested_attributes_for :jobs

devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable, :confirmable

Jobs/new view

<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>


  <%= f.fields_for :jobs do |builder| %>
    <%= render "job_detail_fields", :f => builder %>
  <% end %>

  <%= f.email_field :email, placeholder: "Enter email", class: "full-width form-field" %>

<% end %>

_job_details_fields

<%= f.text_area :job_description, placeholder: "Job description..." %>

The :job_description text_area is not showing. If I change the nested attributes form to something like f.fields_for :job, it will then show but on submission of the form I get unpermitted paramater job as an error. I am pretty sure jobs is correct but I don't know why it is not showing. Any ideas?
