Use the \Magento\Config\Model\ResourceModel\Config::saveConfig() method:

magento/magento2/blob/2.0.0/app/code/Magento/Config/Model/ResourceModel/Config.php#L26-L35


/**
 * Save config value
 *
 * @param string $path
 * @param string $value
 * @param string $scope
 * @param int $scopeId
 * @return $this
 */
public function saveConfig($path, $value, $scope, $scopeId)

magento/magento2/blob/2.0.0/app/code/Magento/Config/Model/ResourceModel/Config.php#L36-L50


{
    $connection = $this->getConnection();
    $select = $connection->select()->from(
        $this->getMainTable()
    )->where(
        'path = ?',
        $path
    )->where(
        'scope = ?',
        $scope
    )->where(
        'scope_id = ?',
        $scopeId
    );
    $row = $connection->fetchRow($select);

magento/magento2/blob/2.0.0/app/code/Magento/Config/Model/ResourceModel/Config.php#L52-L61


    $newData = ['scope' => $scope, 'scope_id' => $scopeId, 'path' => $path, 'value' => $value];


    if ($row) {
        $whereCondition = [$this->getIdFieldName() . '=?' => $row[$this->getIdFieldName()]];
        $connection->update($this->getMainTable(), $newData, $whereCondition);
    } else {
        $connection->insert($this->getMainTable(), $newData);
    }
    return $this;
}

An example of usage from the core:

github.com

magento/magento2/blob/2.0.0/app/code/Magento/Payment/Observer/UpdateOrderStatusForPaymentMethodsObserver.php#L59-L64


$this->_resourceConfig->saveConfig(
    'payment/' . $method->getCode() . '/order_status',
    $defaultStatus,
    'default',
    0
);
