You try this code. Tested Ok

add_action( 'woocommerce_billing_fields', 'my_custom_checkout_fields' );

function my_custom_checkout_fields( $fields ) {

   $fields['billing_developer_name'] = array(
    'label'       => __('Developer name', 'woocommerce'),            
    'placeholder' => _x('Developer name', 'placeholder', 'woocommerce'),  
    'required'    => TRUE,             
    'clear'       => false,             
    'type'        => 'text',              
    'class'       => array('my-css')    
    );

 return $fields;

}

You can arrange it with this snippet

add_filter("woocommerce_checkout_fields", "order_fields");

function order_fields($fields) {

    $order = array(
        "billing_developer_name",
        "billing_first_name", 
        "billing_last_name", 
        "billing_company", 
        "billing_address_1", 
        "billing_address_2", 
        "billing_postcode", 
        "billing_country", 
        "billing_email", 
        "billing_phone"

    );
    foreach($order as $field)
    {
        $ordered_fields[$field] = $fields["billing"][$field];
    }

    $fields["billing"] = $ordered_fields;
    return $fields;

}
