Backend Software Engineer (.NET) - Intern 

Job Description 

Avast (Gen Digital) backend teams based in Brno and Prague are looking for new colleagues to help them build and operate the Order and Subscription Management Platform (OMP). Someone who likes efficient approaches to problem-solving and wants to gain new experiences. Someone who will be a good team player and look forward to new challenges. Does that sound interesting? 

Who we are 

The team is currently divided into 2 feature teams and 1 virtual operation team of Software and QA Engineers. We mainly cooperate online, but we also meet in offices (Prague and Brno). We are an agile team (Scrum, LeSS) working together on the same product/platform (single Product Backlog). Further cooperation is managed internally by teams as needed. 

What are we doing 

We build and operate the Order and Subscription Management Platform (OMP) that integrates Gen Digital e-commerce providers, processes millions of customer orders, and provides unified subscription management. Built on multiple distributed backend services, this platform combines event-driven asynchronous processing (~500k transactions per day) and high availability (~1.5k requests per second). There are currently ~300 million data records and the numbers are still growing. 

The primary development language is C# (.NET 6, .NET 8, and .NET Framework). Data records are stored in SQL databases (MS SQL, PostgreSQL) and views are replicated to distributed NoSQL databases (Cassandra). We also use Redis to cache data. Our microservice architecture provides RESTful API for clients and uses RabbitMQ for messaging. TeamCity and Octopus Deploy are used for automated deployment and release management. Kibana, Grafana, Zabbix and Icinga for logging and monitoring. Tests are automated using Cypress.js.
