Position: Back-end (Scala) Senior Engineer #9744
Company: Lohika
Category: Scala
Experience required: 5y
English level: intermediate

Our team would be working both on backend and frontend of mobile applications connecting millions of clients with thousands of couriers and restaurants owning a whole part of functionality.

Giving an impression on team’s tech stack, 
-	Backend is Scala with Postgres, Redis and Kafka. With the backend services typical stack is http4s + fs2 + cats effect + doobie + quill. Some of old services might use Slick and Play Framework
-	Frontend is React native - based and both major platforms are in the focus.

Most of client’s engineering organisation is in Europe, thus no late meetings.

Nice bonus: you might see couriers with your client’s logo on the streets and even order food using the app you’ve been developing while traveling! Very likely to have them soon in Ukraine too :)
