Principal System Integration Engineer

Job Description

The Department of Technology’s Justice Tracking Information System (JUSTIS) team is responsible for designing, operating, and modernizing the City and County of San Francisco’s criminal justice data exchange platform. JUSTIS enables secure, real-time information sharing among multiple criminal justice partner agencies, supporting mission-critical operations that run 24 hours a day, 7 days a week.

This Principal System Integration Engineer role is a key technical position on the JUSTIS development team, with a primary focus on building and supporting the integration layer that powers the JUSTIS Data Exchange Hub. The position is especially well-suited for a developer who brings deep experience in Oracle-based integration technologies—such as BPEL, SOA Suite, WebLogic, and advanced SQL/PL/SQL—combined with API and web service development skills.

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.

As a member of the JUSTIS development team, the Principal System Integration Engineer is responsible for the design, development, enhancement, and operational support of the JUSTIS Data Exchange Hub and its associated integration services and components. This includes building and maintaining integrations that enable partner agencies to implement system-to-system data exchange, while ensuring high availability and strong data integrity.

This position requires strong technical depth in enterprise integration and Oracle technologies, along with operational awareness and the ability to collaborate effectively across teams and partner agencies.

Essential duties include, but are not limited to, the following:

Oracle Integration & Database Development

• Design, develop, and maintain Oracle database objects including tables, views, complex SQL, and PL/SQL procedures/packages (Oracle 12c/19c).
• Develop, enhance, and support integration workflows using Oracle BPEL and related SOA Suite components to implement business processes and data exchange patterns.
• 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.

Documentation & Team Collaboration

• Produce and maintain technical documentation (e.g., integration specifications, workflow documentation, runbooks, and operational procedures).
• Work collaboratively with other developers, architects, and stakeholders; assist teammates and contribute to shared delivery goals.
• Communicate technical issues and solution options clearly to technical and non-technical partners.
