Working closely with system architects, technical leadership, project management, and partner agencies, the developer performs complex, hands-on development and operational support across development, test, and production environments. This role helps ensure that justice data exchanges are reliable, secure, auditable, and compliant with laws and requirements governing access controls, data protection, and criminal justice information security.

Create and maintain database schemas that represent and support business processes, with strong attention to performance, data integrity, and maintainability. Support and troubleshoot integration solutions built on Oracle WebLogic and SOA Suite, including diagnosing failures across multi-system workflows. Web Services, APIs & Integration Interfaces Design, develop, and maintain web services and integration interfaces that support secure, reliable data exchange across justice partner systems. Implement and support service-based integrations using RESTful services and JSON; maintain working knowledge of SOAP and XML where required. Develop reusable, testable server-side components and integration services, leveraging Python and Java as needed for service development and operational tooling. Middleware, Messaging & Operational Support Support integrations that leverage middleware and messaging technologies (e.g., ActiveMQ and Microsoft message queue) to enable reliable and scalable data movement. Troubleshoot and resolve complex production issues related to integrations, database performance, middleware queues, and service reliability. Support development, test, and production environments for mission-critical, 24x7 operations across multiple justice partner agencies. DevOps, Quality & Release Management Implement and maintain CI/CD pipelines to ensure releases are well-defined, repeatable, and operationally stable. Review, verify, and validate software code to ensure adherence to quality, security, and maintainability standards. Develop and maintain unit and integration tests; support test planning and post-deployment validation.
