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.

Why Contract with Us?

Prepare your application

Use the description above to assess your fit for Hillsborough County. This checklist is guidance from Resumize, rather than additional requirements from the employer. Imported listings can be shortened or change after collection, so confirm the complete description and current availability before sending an application.

Match requirements to evidence

Identify the responsibilities and skills the employer explicitly names. For each important requirement, choose one example from your work, education, training, or projects. Explain what you did, how you did it, and what changed as a result. Include a measurable outcome when you can support it. If you lack a requirement, describe related experience accurately instead of adding an unfamiliar skill to your resume.

Put the most relevant examples near the top of your resume. Keep job titles, dates, qualifications, and contact details consistent across your application materials. Use the employer’s terminology when it describes your experience accurately; a copied list of keywords does not explain your contribution. A short, specific bullet is easier to review than a paragraph that mixes several unrelated duties.

Check the working arrangement

Confirm the location, schedule, employment type, and any eligibility requirements on the employer’s site. A remote label does not establish worldwide eligibility or flexible hours. If compensation, benefits, equipment, travel, or contract duration are missing from this listing, write down your questions for the recruiter. Do not assume details from another opening at the same company apply to this role.

Review before submitting

Follow the employer’s requested file format and application instructions. Open your exported resume and check that its text is selectable, its sections read in order, and its links work. Proofread names, dates, and contact information. Share confidential work samples only when you have permission, and use an anonymized example when necessary.

Submit through a trusted employer or recruiting destination. If the original listing has disappeared, search the employer’s careers page for the title rather than assuming the vacancy remains open. Save the application date, job reference, and the version of your resume you sent. Those details help you prepare for a later conversation and avoid submitting conflicting information through several job boards.

Review your resume for writing and readability feedback, or browse other openings if this opportunity is unavailable.
