Key Responsibilities 1. JasperReports Architecture & Upgrade • • Lead the end-to-end upgrade of Jaspersoft/JasperReports Server from 6.x to the latest supported version. • Assess the existing JasperReports Server architecture, deployment model, configurations, customizations, and dependencies. • Define the upgrade and migration strategy, including sequencing, dependencies, rollback approach, and validation. • Identify and resolve version compatibility issues across JasperReports, Java, Tomcat, databases, authentication mechanisms, and integrations. • Review existing Jasper reports, data sources, repositories, extensions, custom components, and integrations for upgrade impact. • Provide technical guidance on upgrade-related architecture and design decisions. 2. Security Architecture & Hardening • • Assess the current Jasper security architecture and configuration and identify security gaps. • Define and implement a security hardening strategy as part of the upgrade. • Review authentication, authorization, session management, access controls, and security configurations. • Conduct security reviews and coordinate remediation of identified vulnerabilities and security findings. • Ensure appropriate security controls are incorporated into the upgraded environment. • Support security validation and risk remediation before production rollout. 3. Authentication & Enterprise Integration • • Lead the upgrade and validation of enterprise authentication integrations, including: • SSO • SAML • OAuth • LDAP / Active Directory • Assess compatibility of existing authentication configurations with the target JasperReports version. • Troubleshoot authentication, authorization, identity mapping, and access-control issues. • Validate integration with enterprise databases and application ecosystems. • Ensure existing integrations continue to function correctly following the upgrade. 4. Java, Tomcat & Linux Platform • • Assess compatibility between JasperReports Server and the underlying Java runtime, Apache Tomcat, Linux OS, and database platforms. • Lead technical remediation for application-server and runtime compatibility issues. • Review Tomcat configuration, deployment settings, JVM configuration, security settings, and application dependencies. • Troubleshoot application startup, deployment, connectivity, performance, and runtime issues during the upgrade. • Provide technical recommendations for the target platform architecture. 5. Migration, Testing & Stabilization • • Define the migration approach for application configurations, repositories, reports, users, roles, permissions, data sources, and integrations. • Establish technical validation criteria for the upgraded environment. • Support functional, integration, security, and regression testing. • Lead defect analysis and resolution for upgrade-related issues. • Drive post-upgrade stabilization, including production monitoring, issue resolution, and remediation. • Provide technical guidance during cutover and production transition. 6. Architecture & Stakeholder Leadership • • Act as the technical architecture owner for the Jasper upgrade initiative. • Make architecture and technology decisions based on compatibility, security, maintainability, and business requirements. • Produce and review architecture/design documentation, upgrade plans, technical assessments, and security recommendations. • Work closely with application, infrastructure, security, identity, database, and business teams. • Engage with business and technical stakeholders to communicate risks, dependencies, decisions, and progress. • Provide technical leadership to engineering teams without necessarily having direct line-management responsibility. Required Skills & Experience • • 12+ years of overall IT experience, with significant experience in enterprise application architecture, administration, or modernization. • Strong hands-on expertise in Jaspersoft / JasperReports Server architecture and administration. • Proven experience performing JasperReports Server version upgrades, preferably including upgrades from 6.x to newer/latest versions. • Strong understanding of JasperReports Server architecture, configuration, repositories, reports, data sources, users, roles, permissions, and integrations. • Hands-on experience troubleshooting version compatibility and migration issues. • Strong experience with: • Java • Apache Tomcat • Linux • Relational databases • Strong experience with enterprise authentication and identity technologies: • SSO • SAML • OAuth • LDAP • Active Directory • Strong understanding of authentication, authorization, access control, application security, and security hardening. • Experience conducting application security reviews and supporting vulnerability remediation. • Ability to assess existing architecture and define upgrade, migration, security, and stabilization strategies. • Strong troubleshooting and root-cause analysis capabilities. • Experience producing architecture/design and technical review documentation. • Strong stakeholder management and communication skills. • Ability to make architecture decisions and provide technical leadership across multiple teams.
