About The Seafood Inspection Services Portal (SISP) provides a common front door to a variety of NOAA Fisheries Seafood Inspection Services. SISP consists of two web components: Public-facing portal that enables external users (industry participants and stakeholders) to submit and manage service workflows (e.g., certificates, inspection requests, related submissions), make payments through approved payment services (as integrated), and receive electronic outputs (e.g., certificates, approvals, receipts). Private back-end portal used by internal NOAA Fisheries personnel to administer and process submissions, reconcile payments and manage adjustments/refunds where applicable, issue decisions/approvals, and generate ad-hoc and standard operational reports. This effort includes modernizing and migrating legacy data and workflows into SISP, building new workflows, updating legacy data into a cleaner Oracle DB, and developing static and operational reports for the new workflows. The SISP application is implemented using Spring Boot and modern Java, deployed to Tomcat, a dynamic React front end, and supported by an Oracle backend. Key Responsibilities (Spring/API-first, React-connected) Lead backend development using Spring Boot (3.5.6) and Java 21 to build secure, scalable services that power SISP business workflows (e.g., certificates, inspection requests, finance).

Integrate backend APIs with the React front end by coordinating API contracts, payloads, and error semantics; collaborate closely with UI/UX and product to meet usability needs. Support modernization and data migration efforts by analyzing legacy data, reconciling records, and validating data quality.
