nd presentation layers and back-end integration services, you will build secure web services, maintain automated deployment tracks, and orchestrate efficient relational data movement. The ideal candidate will combine deep expertise in enterprise Java/J2EE frameworks with strong front-end UI integration skills to deliver scalable, high-performance software.
Location: Toronto, ON
Duration: 15-month contract.
Advantages
Long-Term Project Runway: A foundational 15-month contract duration provides an exceptional, secure platform to steer multi-phase application rollouts from initial build through post-implementation stabilization.
Elite Technical Intersection: Command a highly marketable professional profile by uniting foundational J2EE enterprise backends and JSF configurations with modern open-source UI libraries.
End-to-End Architectural Impact: Own your features completely—driving code evolution from raw backend relational schema tuning up to front-end layout rendering and CI/CD promotion.
Collaborative Visibility: Maximize your impact by conducting technical design walkthroughs and serving as a key engineering liaison between cross-functional developers, business analysts, and QA teams.
Responsibilities
Full-Stack Application Engineering: Translate complex technical requirements and systems specifications into clean, scalable, and deployable production code. Author detailed programming specifications, compile data-driven programs, and conduct rigorous unit testing.
Component Framework Delivery: Design, configure, and maintain secure server-side components using Java, J2EE, and JavaServer Faces (JSF), alongside core web application servers like Apache Tomcat and Oracle WebLogic.
Front-End Architecture & Integration: Create, design, and implement responsive client-side layouts using HTML5/DHTML, CSS3, JavaScript, jQuery, and Bootstrap, ensuring seamless integration between the user interface and backend services.
API Development & Lifecycle Governance: Design, construct, and integrate robust RESTful (utilizing Swagger definitions) and SOAP web services, prioritizing speed and infrastructure scalability.
Relational Database Programming: Build and expand transactional data pipelines by executing extraction, transformation, and loading (ETL) activities. Construct and tune high-performance Oracle SQL scripts and procedures within relational database management systems (RDBMS).
Tier-3 Troubleshooting & Technical Support: Diagnose, isolate, and resolve complex application bugs and technical issues arising during implementation, data conversions, or multi-environment software migrations.
DevOps & Process Automation: Support continuous integration and deployment (CI/CD) workflows by reviewing, analyzing, and modifying application installation and installation scripts.
Agile Collaboration & Documentation: Participate actively in project ceremonies using Agile, Scrum, and Rapid Application Development (RAD) methodologies. Elicit and document information from diverse stakeholder groups, providing user and system documentation as required.
Qualifications
Core J2EE Seniority: 8+ years of progressive professional experience navigating the entire Software Development Life Cycle (SDLC) in large enterprise landscapes, utilizing Java, J2EE, EJB, and Servlets.
JavaServer Faces (JSF) Mastery: Proven, hands-on development experience implementing user interfaces and component frameworks with JSF is strictly required.
Open-Source Stack Proficiency: Demonstrated experience working with open-source software and frameworks, specifically Spring, myBatis, Bootstrap, and jQuery.
Advanced Database Skills: Strong relational database competency with hands-on experience authoring and optimizing Oracle SQL scripts and data architectures.
Web Services & Protocols: Deep operational knowledge of API architecture, data-interchange formats (XML/XSL, JSON), and designing RESTful or SOAP-based services.
Agile & Tooling Literacy: Practical experience working within an Agile environment utilizing project tracking tools like Azure DevOps, JIRA, and Git version control systems.
Education: Post-secondary education in Computer Science, Software Engineering, or a related technical discipline (or an equivalent combination of formal education and professional experience).
Asset: Prior software development experience operating within Canadian public sector I&IT frameworks, data privacy boundaries, or AODA compliance guidelines.
