  • Diagnose, troubleshoot, and resolve functional and performance bottlenecks across development, testing, and production environments
  • Work actively inside Agile Scrum teams, reviewing peer code, managing pull requests, and validating deployment packages within CI/CD pipelines
  • Author and maintain comprehensive system code documentation, mapping architectural patterns to support long-term knowledge transfer
  • Support dynamic application behavior, data pre-population workflows, and structured data capture aligned with established interoperability standards

Requirements

  • 8+ years of dedicated professional experience designing, building, and maintaining robust Single Page Applications (SPAs) integrated with backend RESTful APIs
  • Expert-level proficiency developing front-end web solutions using Angular, TypeScript, and Bootstrap

  • Solid operational knowledge of modern authentication security frameworks, specifically including OAuth 2.0 and JSON Web Tokens (JWT)
  • Extensive development experience within Agile teams utilizing Azure DevOps suites (including Azure Repos, pull requests, and CI/CD pipelines)
  • Proven experience successfully delivering software engineering or digital application solutions within a structured public sector framework or corporate government setting
  • Bachelor's degree in Computer Science, Engineering, or an equivalent technical discipline

Nice to have

  • Knowledge of backend development concepts, including Java Spring Boot, microservices architecture (Kubernetes, Docker), and relational or NoSQL database management systems
  • Familiarity with Microsoft Azure services (such as Azure Kubernetes Service, Azure Service Bus, and Functions) alongside foundational knowledge of AWS environments
  • Understanding of digital web accessibility rules (AODA and WCAG 2.0 guidelines) and application security best practices
