We are seeking a mid-level .NET Software Developer to support the U.S. Department of State's Bureau of Diplomatic Security (DS) in maintaining and enhancing a business‑critical application. This is a small‑team environment — currently a team of one — requiring a resourceful, self‑directed professional who takes ownership of the full development lifecycle with minimal supervision.

The ideal candidate is a proactive problem‑solver who is equally comfortable digging into legacy code and shipping modern improvements. You will work directly with stakeholders to gather requirements, diagnose issues, and deliver solutions in a secure, government‑regulated environment.

• Own end‑to‑end development, maintenance, and enhancement of an existing .NET web application
• Develop and maintain front‑end components using React and Razor views
• Diagnose and resolve bugs, performance issues, and technical debt independently
• Collaborate with government stakeholders to translate requirements into technical solutions
• Write clean, documented, and testable code following secure development best practices
• Participate in code reviews and contribute to technical documentation
• Coordinate with the client's IT and security teams to ensure compliance with DoS security policies
• Manage deployments and support application environments in accordance with government change control procedures

• 5–7 years of professional software development experience
• Active Secret clearance is required at time of application
• Bachelor's degree in computer science, Software Engineering, Information Technology, or a related field (or equivalent experience)
• Proficiency in C# and the .NET framework (ASP.NET, .NET Core)
• Experience with React for front‑end development
• Experience with Razor Pages / Razor Views (ASP.NET MVC or Razor Pages)
• Working knowledge of SQL Server or equivalent relational database systems
• Familiarity with RESTful API design and integration
• Proficiency with Git or equivalent version control systems
• Demonstrated ability to work independently and self‑manage priorities with minimal oversight
• Strong analytical and troubleshooting skills
• Clear written and verbal communication skills for both technical and non‑technical audiences

• Prior experience supporting U.S. federal government or national security clients
• Familiarity with DoS or law enforcement/security agency IT environments
• Experience with Azure Dev Ops or similar CI/CD platforms
• Knowledge of Entity Framework or other ORM tools
• Type Script experience
