Solution:

public function execute(Observer $observer) {
   $payment_method_code = $observer->getEvent()->getMethodInstance()->getCode();
   if ($payment_method_code == 'paypal_express') {
       $result = $observer->getEvent()->getResult();
       $result->setData('is_available', false);
       if ($this->_customerSession->isLoggedIn()) {
           $customerGroupId = $this->_customerSession->getCustomer()->getGroupId();
           if ($customerGroupId == 9) {
               $result->setData('is_available', true);
           }
       }
   }
}
