Description: * Proven experience with Liferay DXP (preferably 7.2+ or 7.4+). * Knowledge of Java + Liferay MVC development. * Experience migrating Liferay portals (from earlier versions to more recent ones). * Knowledge of Liferay web frameworks: portlets, themes, ADTs, fragments, content structure, and permissions. * Experience with REST APIs, JSON Web Services, and SOAP Web Services (especially in Liferay contexts). * Familiarity with configuration and consumption of SAML 2.0 authentication. * Git, Maven, Gradle, Tomcat, Jenkins, and build/deployment automation tools. Preferred Qualifications: * Prior experience with OpenAM 13 or other SAML providers. * Participation in projects replacing legacy Java applications with native Liferay solutions. * Hands-on experience with containers (Docker, Podman), especially for Liferay environments. * Basic understanding of corporate authentication architecture and Single Sign-On (SSO). * Familiarity with Elastic clusters and large-scale enterprise environments. * Experience working in multidisciplinary teams and using agile methodologies (Scrum/Kanban). You will join a strategic project to migrate the Liferay platform from version 6.2 to version 7.4 DXP, contributing to the complete restructuring of the environment, elimination of legacy Java applications, and modernization of the authentication architecture via SSO (OpenAM + SAML). You will work alongside Liferay architects, analysts, and consultants, developing new features natively on the 7.4 platform, with a focus on adherence to the official technology stack, performance, and technical sustainability. * Provide technical support for migrating the legacy portal (Liferay 6.2 + Java) to the new Liferay 7.4 environment. * Rewrite and adapt functionalities currently implemented in an external Java application to run natively within Liferay (portlets, widgets, custom applications). * Integrate with OpenAM 13 via SAML 2.0, considering federated authentication scenarios. * Analyze legacy artifacts (Document Library, database, source code) and propose solutions compatible with the new technology stack. * Develop and test Liferay components (MVC portlets, fragments, themes, ADTs). * Support QA and production environments, proposing continuous improvements. * Contribute to technical documentation and code reviews. * Collaborate with multidisciplinary teams (infrastructure, architecture, business, and end customers) during agile ceremonies. 2512210202551931759
