Position: Middle .NET Engineer, Tickets Selling System
Company: DataArt
Experience required: 3y
English level: upper

About the vacancy

DataArt is currently helping to modernize the IT system of an independent online retailer of railroad tickets. The company's annual income exceeds 100 million euros. The company is one of the regional leaders in the industry and is currently launching their new product, an international platform for ticket sales.

The client uses various tools to reach their customers, such as a mobile app, a responsive web application, or communicating with them directly through the call center. The system is very complex, it must comply with a large number of regulations. We provide APIs for different clients including the biggest Global Distribution Systems (GDSes). We also provide solutions that are labeled by more than half Train Operating Companies (TOC's) in UK.

Several independent teams are working on the project. The goals of each team are limited to the part of the system they're working on. DataArt's specialists are working on the back-end in one of the teams.

Our client is committed to ensuring that the system will be as modern as possible. It is based on microservice architecture with the use of continuous integration, where a few hundred components operate independently of each other and can be used as they become available. This increases the modularity of the system and optimizes the use of the services. All components run on AWS.

We hire people not for a project but for the company. If the project (or your work on it) is over you go to another project or to a paid “Idle”.
