Consultant II - LEA (Logistics Execution Architecture)

At Logistics Reply, we are hiring a Full Stack Developer on the LEA Delivery Team, a key player in building and customizing our proprietary logistics applications. LEA is a powerful, Java-based framework, and a deep understanding of its architecture is essential for success.
She/he will be responsible for developing and configuring both the front-end and back-end components of the platform for our clients.
This role requires a unique blend of modern back-end skills (Java, Groovy, Apache Camel), the ability to master a legacy front-end (a customized YUI framework), and strong domain knowledge in logistics.

Responsibilities:
• Full-Stack Development: Design, develop, and maintain front-end applications using our custom SCE UI framework (built on YUI 3 and Handlebars.js), which interacts with back-end services via REST APIs.
• Back-End Logic & Integration: Extend and configure back-end services SCE BE using Java (Jakarta EE, CDI), Groovy, and integration frameworks like Apache Camel. Implement business logic using tools like Camunda decision tables.
• Reverse Engineering: Analyze, debug, and reverse-engineer a complex, mature Java codebase to troubleshoot issues, implement new features, and perform refactoring.
• Collaboration: Work closely with business analysts and project managers to translate complex logistics requirements into technical solutions. Ensure all customizations are well-designed, documented, and tested.
• DevOps & Version Control: Manage the application build process, dependencies, and deployments. Strictly adhere to Git best practices, including branching models (GitLab Flow) and commit strategies.
• Release Management: Manage the end-to-end product release process for individual tenants, coordinating and executing deployments to deliver updates and new functionalities.
• Process Improvement: Actively contribute to improving team processes through rigorous code reviews, promoting modular configuration, and enhancing documentation.

Minimum Requirements :
• Java & Integration Expertise: Solid experience in back-end development with Java (Jakarta EE, CDI), Groovy, and integration frameworks like Apache Camel.
• Build & Dependency Management: Deep understanding of the Maven build lifecycle, including how it compiles the Java codebase and how to effectively manage complex cross-module dependencies.
• Middleware & Infrastructure: Hands-on experience with enterprise middleware, including application servers (e.g., WildFly), message brokers (e.g., ActiveMQ), and event streaming platforms (e.g., Kafka).
• Legacy Front-End Experience: Proficiency in JavaScript and experience working with non-SPA front-ends. Direct experience with YUI (Yahoo! User Interface Library) or the ability to quickly master a legacy framework is essential.
• Reverse Engineering Skills: Proven ability to dive into a large, existing codebase, understand its functionality without complete documentation, and make targeted enhancements.
• CI/CD and Git Mastery: Hands-on experience building applications using CI/CD pipelines (Bamboo preferred) and expert-level proficiency with Git, including branching models and strategies.

Preferred Qualifications:
• Logistics Domain Knowledge: A strong understanding of logistics, supply chain management (SCM), or warehouse management (WMS) concepts is preferred to effectively understand project requirements and the existing codebase.
• Container Orchestration: Knowledge of containerization and orchestration (e.g., Kubernetes, Ingress) is highly desirable and will be given strong consideration.
• BPMN Tools: Experience with Business Process Model and Notation (BPMN) engines, particularly Camunda and its DMN decision tables.
• Web Server Administration: Familiarity with Apache HTTP Server is a plus.
• Modern JavaScript: While not the primary technology, experience with modern JavaScript frameworks (React, Angular, Vue.js) is a plus.
