• Hands-on experience designing RESTful APIs and documenting with OpenAPI/Swagger.
• Practical experience querying and integrating OpenSearch or Elasticsearch.
• Baseline understanding of event-driven architectures and data streaming (Kafka, CDC/Debezium).
• At least 3 years of experience in an Agile/SAFe/Scrum environment building enterprise products.
• Experience with Docker, Kubernetes/OpenShift, Helm, or GitOps deployment workflows.

Qualifications
