Jooble — is a Ukrainian IT company whose product is used by more than 90 million monthly users in 69 countries all around the world.

Jooble’s Product — a worldwide employment website that is the second most visited employment service in the world and is among 500 top visited websites globally, according to SimilarWeb.

Jooble is a remote-first company. We believe that talented people can create cool projects no matter where they are. Yet if you like to work from the office — for all employees we have created closed corporate workspaces in Kyiv, Uzhgorod, and Lutsk that are free to be used anytime.

Our purpose — help people all over the world find their dream jobs!

Due to the constant development of the product, we want to strengthen our team with several .NET Developers.

Jooble’s product from the technological perspective

Our website is built upon microservices architecture. We use the latest versions of .NET and ASP.NET Core to create new services and applications. Message queuing with RabbitMQ allows transferring data between services and applications in the most effective way. To improve application performance, we implement caching using Redis. Our main front-end framework is react.js. To balance the load across multiple site instances, we use NGINX. In a bundle with Consul, NGINX balances the traffic among several microservices instances according to set up configurations.

Massive volumes of data are stored in numerous MSSQL and PostgreSQL relational databases. Since our website is a search engine, we use Elasticsearch to access data quickly. Along with Elasticsearch, we use other instruments of Elastic Stack. For example, Logstash and Kibana allow keeping an eye on error logs of our software.

Together with DevOps, our Developers implement the best CI/CD practices using GitLab and Jenkins. Using Prometheus, we gather performance metrics of our services and applications and then visualize them on Grafana dashboards.
