  • API Architecture & Integration: Design, build, and maintain commercial RESTful and SOAP API services. Implement advanced runtime strategies for API gateways, including load balancing, service discovery, traffic throttling, and circuit-breaking resiliency patterns
  • Front-End Development: Build responsive, modular, and reusable user interface components using React (along with Angular/AngularJS utilities) to ensure an optimized client-side experience and seamless UI-to-API communication
  • Back-End & Framework Delivery: Orchestrate complex server-side enterprise applications utilizing the Spring Framework, EJB, Servlets, and Java application servers such as Tomcat and Oracle WebLogic
  • DevOps & CI/CD Automation: Configure, manage, and scale deployment automation frameworks using IBM UrbanCode release management suites and Azure DevOps pipelines to continuously build, test, and deploy applications
  • Database & Data Pipeline Management: Design relational database structures (Oracle, SQL Server), write highly optimized SQL queries, and construct automated ETL pipelines to handle complex data ingestion, transformation, and movement
  • Technical Problem Solving: Diagnose, troubleshoot, and resolve critical tier-3 issues during systems implementation, legacy database conversions, and multi-environment software migrations
  • Governance & Standards Compliance: Participate in architecture design walkthroughs and maintain strict code compliance with corporate data security policies and the Accessibility for Ontarians with Disabilities Act (AODA)

Requirements

  • J2EE Mastery: 10+ years of dedicated professional experience utilizing J2EE development tools, enterprise Java programming languages, and hosting platforms (WebLogic/Tomcat)
  • Spring Framework Seniority: 10+ years of hands-on experience building enterprise backend solutions with the Spring Framework
  • DevOps Tooling Seniority: 10+ years of proven working experience automating release management, configuration scripting, and continuous delivery with IBM UrbanCode tools
  • Front-End Proficiency: Demonstrated engineering experience building complex user-centric web applications with the React framework, HTML5, CSS3, and modern JavaScript modules
  • Advanced API Engineering: Deep practical knowledge of designing resilient API architectures (load balancing, discovery, fallback caching mechanisms) and working with OpenAPI/Swagger definitions
  • Domain Context: Direct, prior project experience working on the Digital Dealership Registration (DDR) project or highly similar public-sector registry solutions
  • Education: Bachelor’s degree in Computer Science, Software Engineering, or a related technical discipline (or an equivalent combination of formal education and experience)

What we offer

  • High-Impact Domain Leadership: Lead the technical expansion of the mission-critical DDR project, directly improving transactional velocity and enterprise platform connectivity
  • Elite Technical Depth: Maximize your market value by commanding an exceptionally robust full-stack architecture that unites standard Spring backends, React frontends, and enterprise UrbanCode automation
  • End-to-End Architectural Impact: Own your features completely—from data mapping, schema tuning, and API gateway routing down to custom UI rendering and CI/CD pipelines
  • Stable Daytime Operations: Benefit from a predictable, highly structured 7.25-hour daily work model within a professional, collaborative engineering branch in downtown Toronto
