What you'll do
Engineering at Zenjob
Technology is core to Zenjob's vision. Our engineers from all over the world are building the services that power our platform – our mobile and web apps, our matching core, and the digital document management system. Engineering works alongside Product to support every department to create value for our users and customers. We love to adopt new technologies, and strive for ownership and excellence to build the work platform of the future. To achieve this goal, we base everything we do on our 5 engineering principles: speed, simplicity, stability, scalability and security.
Zenjob wants to create a great experience for both talents looking for work, and companies searching for part-time help. To meet our users needs we are organised into two value streams with multiple cross-functional teams. A third value stream provides the infrastructure, as well as shared services.
On top of that, we are building an internal engineering community that supports our growing team and maintains best practices and technical excellence throughout the department. Building a large scale platform is not only a technical challenge, but an exciting social and organisational one as well.

This is a special shoutout to people from underrepresented groups to come shaping the future of work with us!
Our tech stack
Our platform is powered by AWS, Kubernetes, Istio, Terraform and Docker. These tools form the foundation that allow us to deploy and scale fast and easily. Everything is monitored and logged by Prometheus and Grafana including request tracing for better observability.
Our microservices and backends are running on Nodejs, and Java with Spring Boot and Groovy, which include easy-to-use templates for new microservices.
On the client-side we run on React and Redux with the help of a Microfrontends for the web, while we use Swift for iOS and Kotlin for our Android Apps.
We test our software by using Selenium, JUnit, Spock, and React-testing-library.
We store data in various persistence technologies like Kafka-Streams, Postgres and Redis, while also using SQS and REST for both asynchronous and immediate service-communication. We make use of technologies like ElasticSearch to perfectly match talents to the right job.
We empower our teams to experiment with new technologies by using our Technology Radar, in order to give great user experience for our customers. The insights we gain from our users flow back into our product development through A/B testing and constant feedback.
