Node.js spawn multiple SQS listeners threads in one project

I have a Node.js project that is consuming messages off AWS SQS (a message queue). I would like to spin up multiple consumers in the same project to keep up with the messages placed in the queue without having to create another Node.js instance. Is it possible to do that with something like Fibers or another framework? I'm basically trying to make this multithreaded.

Here's an example:

var AWS = require('aws-sdk'),
    nconf = require('nconf'),
    SQS_URL = process.env.SQS_SERVICES_EVENTS;

AWS.config.update({accessKeyId: nconf.get("accessKeyId"), secretAccessKey: nconf.get("secretAccessKey")});
AWS.config.update({region: nconf.get("region")});

// Initialize SQS
var sqs = new AWS.SQS();

// Params for SQS
var MAX_NUM_MSGS = nconf.get("sqs.max.messages");
var params = {
    QueueUrl: SQS_URL,
    MaxNumberOfMessages: MAX_NUM_MSGS,
    VisibilityTimeout: 30,
    WaitTimeSeconds: 20
};

exports.startSqsListener = setInterval(sqsListener, nconf.get("sqs.interval"));

// Make multi-threaded
function sqsListener() {
    sqs.receiveMessage(params, function(err, data) {
        if (err) {
            logger.error(err, err.stack);
        }
        if (data.Messages) {
            // do something with each message
        }
    });
}
