• 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.

• 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).
• Design and implement RESTful APIs (request/response models, validation, error handling, pagination/filtering, versioning) enabling efficient communication between the React front end and backend services.
• Implement security controls with Spring Security, including authentication/authorization, role‑based access, and secure coding practices aligned with OCIO requirements.
• Develop persistence and data access layers using Spring Data JPA / Hibernate, working with complex Oracle schemas; write and optimize SQL, stored procedures, and routines; troubleshoot and tune application/database performance.
• Define and enforce backend architecture and coding standards, including a multi‑controller approach (one controller per workflow) and adoption of Google's Java Style Guide; conduct code reviews and mentor developers.
• 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.
• Contribute to CI/CD and Dev Ops best practices, improving automation and delivery reliability using Git‑based workflows and pipelines.
• Participate across the full SDLC (design, development, testing, deployment, and O&M) in an Agile/Scrum environment; collaborate with product managers, designers, QA, and stakeholders; maintain technical documentation using the recommended tooling.
• Build & Version Control Tools
• Experience using Maven for build and dependency management (Gradle familiarity beneficial)
• Proficiency with Git workflows using Git Hub/Git Lab

• Experience developing customized workflow applications, data entry applications, law‑related business applications, and some level of GIS expertise.
• Experience with Docker/Kubernetes practices (where applicable in the target environment).
• Experience producing and maintaining operational documentation and runbooks for O&M phases.
• Experience with Developing and maintaining forms using OAS BI Publisher.
• Experience in reporting tools, such as tableau
