  • Deploy and manage applications on GCP cloud infrastructure.
  • Implement and manage containerization using Docker and Kubernetes.
  • Develop and maintain CI/CD pipelines using Jenkins.
  • Utilise Git for version control and collaboration, and conduct code reviews.
  • Work with databases (SQL and NoSQL), optimize queries for performance, and demonstrate a strong understanding of database concepts.
  • Participate in Agile ceremonies (daily stand-ups, sprint planning, retrospectives).
  • Troubleshoot and resolve complex technical issues, and provide root cause analysis.

What you will need to have:

  • Extensive experience with Java programming principles and object-oriented design (+ 8 years).
  • Expertise in Spring Boot, Spring Security, and other Spring ecosystem components.
  • Proven experience with both microservices and monolithic application development.
  • Strong understanding of GCP cloud technologies and hands-on experience with Docker and Kubernetes.

  • Extensive experience with Git and CI/CD pipelines using Jenkins.
  • In-depth knowledge of software development principles and best practices.
