For nested object it is simple just define properties below with an indentation so your route definition would be

@swagger
/api/v1/employees/add:
  put:
    tags:
      - Employees
    summary: "Create a new employee"
    description:  
    produces:
      - application/json
    security:
     - api_key: []
     - api_token : [] 
    parameters:
      - name: body
        in: body
        description:
        required: true
        schema:
           type: "object"
           properties:
              employee_code:
                 type: "string"
              mobilenumber:
                 type: "string"
              firstname:  
                 type: "string"
              lastname:
                 type: "string"
              emailid:
                 type: "string"
              is_login_enabled:
                 type: "boolean"
              address_line1:  
                 type: "string"
              address_line2:
                 type: "string"
              town:
                 type: "string"
              city:
                 type: "string"
              state:  
                 type: "string"
              pincode:
                 type: "string"
              designation:
                 type: "string"
              joining_date:
                 type: "string"
                 format: "date-time"
              releiving_date:
                 type: "string"
                 format: "date-time"
              is_active:  
                 type: "boolean"
              account_id:  
                 type: "number"
              user:
                 type: "object"
                 properties:
                    username:
                       type: "string"   
                    role_id:
                       type: integer
                    reference_object:  
                       type: "string"
                       example: "employees"
                    password:
                       type: "string"
                    password_secret:
                       type: "string"
    responses:
      200:
        description: Employee created successfully
      204:
        description: No data found

It looks like this in the Swagger UI.

Make sure to have the proper indentations when placing it.
