• Strong debugging, code-review, documentation, and stakeholder communication skills.
• Ability to work independently and collaborate with architects, security engineers, QA staff, analysts, and Government stakeholders.
• Active Department of Defense TS/SCI clearance.
• DoD 8140/8570 baseline certification appropriate for the assigned role.

Responsibilities

• Design, build, test, and maintain full-stack applications using Node.js, Express, JavaScript/TypeScript, and SQL Server or Azure SQL.
• Own features across the user interface, API, business-logic, integration, and data-access layers.
• Lead the migration from an embedded database to Azure SQL, including asynchronous data access, SQL-dialect conversion, versioned migrations, connection management, and performance tuning.
• Build secure, versioned REST APIs with consistent validation, error handling, structured logging, authentication, and authorization.
• Preserve critical security controls, including deny-by-default authorization, role- and scope-based access, protected-data masking, and complete audit logging.
• Implement enterprise identity capabilities such as CAC/PIV authentication, DoD PKI integration, certificate validation, secure sessions, and server-side access control.
• Build and maintain secure integrations with external systems using well-defined and version-controlled contracts.
• Use approved AI-assisted development tools to accelerate analysis, implementation, refactoring, testing, debugging, and documentation.
• Review and validate AI-generated changes for correctness, security, performance, accessibility, licensing, and maintainability.
• Develop accessible user experiences that conform to applicable Section 508 and WCAG 2.1 AA requirements.
• Write reliable unit, integration, API, security, accessibility, and end-to-end automated tests.
• Remediate OWASP, DISA Application Security and Development STIG, and other application-security findings.
