Design, develop, unit test, and complete peer review for new features that expand mission capabilities from concept through production release.
Set the technical direction for new functionality, enhancements, and change requests, including accurate effort estimation.
Use AI tools to accelerate solutioning, including design exploration, prototyping, code generation, test scaffolding, documentation, and troubleshooting (you will use AI tools; you will not build AI/ML models).
Build scalable, secure web applications using ASP.NET, C#, SQL, and Angular.
Work with Business Analysts and QA to interpret requirements and deliver against them.
Collaborate with the development team and federal technical stakeholders to plan and execute feature delivery.
Participate in code reviews and apply secure, defensive coding practices throughout development.
Keep current on tools and techniques, including AI-assisted development, to improve delivery speed and quality.

U.S. Citizenship required and non-negotiable.
Hybrid schedule: 2 days a week in the Rockville, MD office required and non-negotiable.
Active Public Trust required.
Ability to pass multiple background and employment checks (federal and local).
Bachelor’s degree in Technology, Business, or Related Field.
8+ years professional ASP.NET / C# back-end development with SQL databases.
8+ years professional Angular, HTML, CSS, and JavaScript front-end development.
Experience with .NET Core / modern .NET (8+).
Proven delivery experience for new functionality in complex, workflow-driven enterprise systems.
Hands-on use of AI code assistants in day-to-day work (e.g., GitHub Copilot, Claude, TabNine).
Ability to apply AI tools effectively across design, prototyping, coding, testing, and documentation.
Sound judgment on where AI accelerates work versus where human review and secure-coding discipline must govern output.

Work AI-fluently to deliver better and faster outcomes.
Focus areas include design exploration, prototyping, code generation, test scaffolding, documentation, and troubleshooting.
Role expectations are about using AI tools, not engineering AI/ML systems.

Experience delivering on federal programs and working with government technical stakeholders.
Familiarity with Azure (App Services, Functions, Key Vault) and cloud-native delivery.
Familiarity with Databricks.
Experience designing and building AI agents that use LLMs to plan, make decisions, call tools, and complete multi-step tasks with minimal human intervention.
Strong grounding in OOP, SOLID, RESTful APIs, microservices, Git, and CI/CD.
Secure coding fluency: input validation (SQL injection, XSS), RBAC, MFA, OAuth/JWT, logging, and error handling.
Azure certifications (e.g., AI-102, Azure Architect) are a plus.
