Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
The developer will own the end-to-end development, maintenance, and enhancement of a business-critical .NET web application for the Bureau of Diplomatic Security. This includes collaborating with stakeholders to translate requirements into technical solutions and managing deployments in a secure government environment.
Candidates must have 5-7 years of professional software development experience and an active Secret clearance. A bachelor's degree in a technical field and proficiency in C#, .NET, and React are required.
The Opportunity:
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.
Responsibilities:
• 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
Qualifications:
Required:
• 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
Desired:
• Prior experience supporting U.S. federal government or national security clients
• Familiarity with DoS or law enforcement/security agency IT environments
• Experience with Azure DevOps or similar CI/CD platforms
• Knowledge of Entity Framework or other ORM tools
• TypeScript experience
