Hi,

Marius here - VP Engineering for Citymapper (powered by Via)

We are excited about the opportunities this creates for the product and team. We are looking forward to join an excellent tech company. Happy to answer any questions.

And we are hiring as we are expanding our product and team. For openings to work on the Citymapper app and tech please visit https://citymapper.com/jobs or write to [e-mail]

Hi, your app depends on Google. I can't use it on LineageOS without installing Google services. Isn't Google your top competitor ? Isn't it a problem, that to use your app you need to use an OS that comes with an uninstallable version of Google Maps ?

Thank you Marius and team. I'm a long time daily user, and I just love what you've built

Can I expect a somewhat lesser focus on European cities in 1 to 2 years while VIA expands its capabilities on Northern America?

[marius-s]

There is actually a great coverage area overlap between VIA and Citymapper - esp. in North America and Europe. I wouldn't expect Europe not not be a focus given the huge transit market size.

Congrats Marius, and everyone else at CM!

Congrats to the team!

Could you give an idea about the tech stack powering citymapper?

[marius-s]

Thanks - and good question.

We run a large deployment of services to support millions of daily active users across the 450+ cities that the Citymapper app operates in - all on AWS EKS. Most of the code of the backend services is written in Python and we have CPP and some Go services or modules as we deal with a lot of CPU and memory intensive workloads (eg routing) as well as high I/O workloads (we are using 1000s of different data sources)

The apps and SDK are written in Kotlin / Swift / React
