Full Stack Developer (TS Cleared Only

Description

Hyer Tek is a federal technology consulting firm delivering secure enterprise applications, data analytics, cloud infrastructure, and modernization services to federal government agencies.

Hyer Tek is seeking a Senior Full-Stack Engineer to build, secure, and modernize enterprise applications operating in Azure Government and classified environments. This is a hands-on senior engineering position—not a people-management role—with primary responsibility for Node.js, Express, JavaScript/Type Script, REST APIs, and SQL Server or Azure SQL.

You will help modernize an established application from an embedded database to a production-grade Azure SQL architecture while preserving its functionality, access controls, integrations, and audit history. You will work alongside solution architecture, cloud, Dev Sec Ops , cybersecurity, business analysis, analytics, and QA professionals on an integrated delivery team.

AI-assisted development is central to how this team works. You will use approved coding agents and development tools to analyze repositories, plan changes, generate and refactor code, create tests, troubleshoot defects, and maintain documentation. You will remain accountable for the quality, security, and maintainability of everything delivered.

• Design, build, test, and maintain full-stack applications using Node.js, Express, JavaScript/Type Script, 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.
• Support containerized deployment through Git Hub Enterprise and Azure Dev Ops pipelines using hardened images and automated quality and security gates.
• Participate in design reviews, pull-request reviews, sprint activities, demonstrations, Government acceptance, and production troubleshooting.
• Produce technical documentation and as-built materials suitable for customer handoff.

• 7+ years of hands-on software-development experience supporting production enterprise applications.
• Strong professional experience with Node.js, Express, modern JavaScript, and Type Script.
• Experience building full-stack web applications, REST APIs, background services, and database-backed business systems.
• Strong SQL and relational data-modeling skills, including SQL Server or Azure SQL, T-SQL, transactions, schema migrations, indexing, and referential integrity.
• Experience modernizing a mature application or completing another large, cross-cutting refactor without regressing system behavior.
• Experience implementing authentication, authorization, role-based access control, and secure session or token management.
• Experience with automated testing, Git, pull requests, CI/CD pipelines, and container-based deployment.
• Working knowledge of secure coding and experience addressing application-security findings.
