I think I've found the solution on this page https://groups.google.com/forum/#!topic/elastica-php-client/WTONX-zBTI4 Thanks Cassiano

Basically you need to extend the FOS\ElasticaBundle\Doctrine\ORM\Listener so you can look for related entities and then update their index as well.

class CompanyListener extends BaseListener
{

    /** @var \Symfony\Component\DependencyInjection\ContainerInterface */
    private $container;

    public function setContainer(\Symfony\Component\DependencyInjection\ContainerInterface $container) {
        $this->container = $container;
    }

    protected function initialiseJob() {
        $this->objectPersisterJob = $this->container->get('fos_elastica.object_persister.application.job');
        $this->em = $this->container->get('doctrine')->getEntityManager(); //maybe move this to postUpdate function so it can be used for all
    }

    /**
     * @param \Doctrine\ORM\Event\LifecycleEventArgs $eventArgs
     */
    public function postUpdate(LifecycleEventArgs $eventArgs)
    {
        /** @var $entity Story */
        $entity = $eventArgs->getEntity();

        if ($entity instanceof $this->objectClass) {
            if ($this->isObjectIndexable($entity)) {
                $this->objectPersister->replaceOne($entity);
                $this->initialiseJob();
                foreach ($entity->getJobOpenings() as $job) {
                    $this->objectPersisterJob->replaceOne($job);
                }
            } else {
                $this->scheduleForRemoval($entity, $eventArgs->getEntityManager());
                $this->removeIfScheduled($entity);
            }
        }
    }

    public function preRemove(\Doctrine\Common\EventArgs $eventArgs)
    {
        $entity = $eventArgs->getEntity();

        if ($entity instanceof $this->objectClass) {

            $this->scheduleForDeletion($entity);
            $this->initialiseJob();
            foreach ($entity->getJobOpenings() as $job) {
                $this->objectPersisterJob->replaceOne($job);
            }
        }
    }


}

and your services defined as below

fos_elastica.listener.application.company:
    class: 'xxx\RMSBundle\EventListener\CompanyListener'
    arguments:
        - '@fos_elastica.object_persister.application.company'
        - 'xxx\RMSBundle\Entity\Company'
        - ['postPersist', 'postUpdate', 'postRemove', 'preRemove']
        - id
    calls:
        - [ setContainer, [ '@service_container' ] ]
    tags:
        - { name: 'doctrine.event_subscriber' }

this will then update indexes for both :-)
