The IT Operations Team

In IT Operations we follow an “Infrastructure as code” philosophy to deploy and manage the many servers that allow commuters all around the world to buy their tickets on their mobile phones. We recognise that this is a really big responsibility and we are proud and excited to be able to make such a big impact on people’s daily lives. There are 5 of us in this team which includes an Ops manager and a service desk person.

We enjoy working with our devs! They are an awesome bunch that feel the same way about our product as we do, so we try our best to give them all the support and tools they need to deliver this high impact product. We don’t like getting in the way, so in general, we try to enable others to do things themselves, by automating as much as possible and giving them the buttons to push. This isn’t easy because the environment needs to be PCI compliant, but we see that as a cool challenge, and so far we are doing great!

We also love AWS. AWS services like EC2 and RDS allow us to do so much with so little, so we use it as much as possible and try avoid deploying anything to our in-house VMware cluster. We also like Docker – we don’t love it yet, but who knows :)

We have a lot of fun in Ops, but when the business needs us, we are there for them. We believe that it is our personal responsibility to ensure that our commuter friends in Boston or Athens or New York are able to ride the train/bus with our app, so we do everything that it takes to ensure that can happen.
