About the Role

We are seeking a highly skilled Senior Full Stack .NET Web Developer with deep expertise across the full web stack — from server-side C#/.NET services to modern JavaScript front ends — to join our technology team. The ideal candidate will bring at least a decade of professional software development experience, with a strong track record of designing, building, and maintaining polished, secure, and high-performing web applications. This role requires a blend of technical excellence, UI/UX sensibility, problem-solving, and leadership to architect, build, and optimize mission-critical, public-facing web systems.
Key Responsibilities

- Design, develop, and maintain responsive, accessible web applications using ASP.NET Core (MVC/Razor Pages) and modern JavaScript/TypeScript frameworks such as React, Angular, or Vue.

- Build and maintain RESTful/GraphQL APIs and backend services in C#/.NET that power front-end applications and integrate with SQL Server and other enterprise systems.

- Translate UI/UX designs and wireframes into clean, semantic, cross-browser HTML5, CSS3, and JavaScript/TypeScript.

- Architect scalable, secure, and performant front-end and back-end web architectures, including component libraries, state management, and reusable UI patterns.

- Ensure web applications meet accessibility (WCAG 2.1 AA) and web security best practices, and are optimized for performance across browsers and devices.

- Collaborate with cross-functional teams, including product, UX/design, QA, and business stakeholders, to deliver end-to-end web solutions.

- Support cloud-based hosting and deployment initiatives using Azure (App Service, Azure DevOps, CI/CD pipelines).

- Mentor junior developers and contribute to front-end and back-end technical best practices, code reviews, and architectural discussions.

- Build and optimize CI/CD pipelines to ensure rapid, reliable, and automated web application deployments.

- Monitor, troubleshoot, and optimize web application performance, scalability, and reliability in production.

Required Qualifications

- 10+ years of professional software development experience, with a strong emphasis on web application development.

- Proven expertise in C#/.NET (Core/Framework), including ASP.NET Core MVC/Razor Pages and building RESTful APIs.

- Strong proficiency in modern JavaScript/TypeScript and hands-on experience with at least one major front-end framework (React, Angular, or Vue).

- Solid command of HTML5, CSS3, and responsive, cross-browser design principles.

- Proven experience with SQL Server (or comparable relational databases) and strong SQL query and optimization skills.

- Experience implementing web accessibility standards (WCAG 2.1 AA / Section 508).

- Experience with Azure, including App Service, DevOps/CI-CD pipelines, and cloud deployment for web applications.

- Strong understanding of web application security best practices (authentication/authorization, OWASP Top 10, data protection).

- Excellent problem-solving, troubleshooting, debugging, communication, and leadership abilities across front-end, back-end, and database code.

Preferred Qualifications

- Experience with public sector or government web applications.

- Demonstrated ability to leverage generative AI and AI-assisted development tools to improve code quality, code review, refactoring, unit-test creation, troubleshooting/debugging, and technical documentation while validating generated output for accuracy and security.

- Experience with SharePoint, Power Automate, or other Microsoft 365 integration technologies.

- Relevant technical certifications in web development, .NET, Azure, or JavaScript frameworks.

- Prior experience leading small development teams or mentoring peers.
