  • UI/UX Engineering: Collaborate with designers and product teams to build intuitive, responsive, and accessible user interfaces using HTML5, CSS3, Angular, and WCAG standards.
  • API & Service Architecture: Develop and maintain RESTful APIs and backend services using .NET Core and C#, ensuring secure, performant, and reusable integration across systems.
  • Database Engineering: Integrate and optimize relational databases such as SQL Server by applying expertise in query design, indexing, and ORM tools like Entity Framework to support data-driven applications.
  • DevOps & CI/CD Automation: Configure and manage CI/CD pipelines using Azure DevOps and GitHub to streamline code deployment, testing, and release processes across environments.

The ideal candidate will possess the following desirable qualifications:

  • Experience implementing observability stacks using tools like OpenTelemetry, Grafana, Prometheus, or Application Insights to monitor and optimize system health.
  • Familiarity with AI-enhanced coding tools such as GitHub Copilot, Tabnine, or use of large language models (LLMs) for code generation, refactoring, or documentation.
  • Experience designing robust automated testing frameworks using tools like Cypress, Playwright, xUnit, or Jest, with integration into CI/CD pipelines.
  • Proven success integrating enterprise systems across domains such as HRIS, CRM, ERP, or e-commerce platforms, with attention to data governance and interoperability.
