Job Technologies
Your role in the team
- You will play a key role in transforming a production-proven solution into a highly scalable, distributed platform that serves enterprise clients across the globe.
- This includes actively shaping architectural decisions, optimizing performance, and contributing to the gradual migration away from a monolithic foundation.
- Design and implement scalable, service-oriented solutions in Kotlin (2+) and Java (21), aligned with our growing performance and availability requirements.
- Contribute to the platform’s evolution by refactoring legacy components and improving the robustness of the system under increasing loads.
- Collaborate across teams to modernise architecture and build new features that are resilient, observable, and horizontally scalable.
- Work with our technology stack: Kotlin (2+), Java (21), Spring Framework, Micronaut, Apache Kafka, Apache Camel, Apache Artemis JMS, Hibernate, Kubernetes, Helm, REST, SOAP, MySQL, PostgreSQL, Elasticsearch, and the Elastic ELK Stack.
- Use modern developer tools like JetBrains IntelliJ + AI, Datagrip, Lens, Rancher, and Postman to streamline development.
- Build and maintain CI/CD pipelines using GitLab to ensure rapid, safe, and repeatable deployments.
- Take part in architectural discussions and influence key technology decisions as we continue scaling globally.
