  • 5+ years of experience working with Apache Kafka or similar distributed messaging platforms in asynchronous or event-driven architectures.
  • 5+ years of experience working with containerization and orchestration technologies such as Docker and Kubernetes for application deployment, scaling, and troubleshooting.
  • Experience with relational and non-relational databases such as MySQL, MongoDB, or similar platforms, including data access and query optimization.
  • Experience using Git and modern continuous integration and continuous deployment (CI/CD) tools in Agile software delivery environments.
  • Bachelor's degree in computer science, software engineering, or a related field, or equivalent combination of education, related experience and/or military experience.

Experience that would be great to have:
