I don’t really see enough here to tell what could be causing an infinite loop. The only error that I see is with the meta_query. If this is a user field then ACF stores a serialized array of user IDs and you need to do something like
$query_args = array(
'numberposts' => -1,
'post_type' => 'job',
//Only grab jobs where current user ID is in the team field
'meta_query' => array(
'key' => 'team',
'value' => '"'.$current_user->ID.'"',
'compare' => 'LIKE',
)
);
