Job Summary / Key Skills:

Please note; this is NOT pure back-end development - it will also include maintaining configurations and data transformations. Many of the existing microservices developed with Spring Boot and Apache Kafka are reusable.

• Lead and co-own the development of modern microservices using Spring Boot
• Design and implement secure systems with Spring Security
• Work hands-on with Kubernetes for deployment and orchestration
• Collaborate on complex integrations in a fast-paced, distributed environment
• Explore and adopt technologies like Apache Camel and Kafka
• Contribute to our API management and IoT-driven solutions

• 3-5 years of professional Java development experience
