Job description

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

A successful candidate will help modernize an established application, working across the full application stack while migrating its embedded database to a production-grade Azure SQL architecture and preserving its functionality, access controls, integrations, and audit history. You will collaborate with solution architects, cloud, DevSecOps, cybersecurity engineers, business analysts, and QA professionals on an integrated delivery team.

Approved AI-assisted development tools are integrated into the team’s software engineering workflow to accelerate repository analysis, development, testing, trouble shooting, and documentation. A successful candidate will use approved coding agents and development tools to analyze repositories, plan changes, generate and refactor code, create tests, troubleshoot defects, and maintain technical documentation. The Senior Software Engineer will remain responsible for validating AI-generated output and ensuring the quality, security, performance, and maintainability of all delivered software.

Candidates must possess a Top Secret security clearance and reside in the Washington, DC, metropolitan area. Some work will be performed at customer facilities, including accredited Secure Areas and SCIFs at Fort Meade.

Responsibilities

• 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 GitHub Enterprise and Azure DevOps 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.
• Collaborate with cloud, DevSecOps, and cybersecurity engineers, QA, and business analysts to identify and resolve application performance, security integration, and operational issues.

Requirements

Required Qualifications

• 7+ years of hands-on software-development experience supporting production enterprise applications.
• 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 practices and experience addressing application-security findings.
• Experience using GitHub Enterprise and/or Azure DevOps for source control, code review, work tracking, and automated delivery.
• Hands-on experience using AI-assisted development tools or coding agents in professional software-delivery workflows.
• Ability to give AI-assisted development tools clear context and constraints and independently validate the resulting code through code review, automated testing, security analysis, and functional validation.
• Strong proficiency in AI platforms including Open AI, Claude, Gemini, and Microsoft CoPilot.
• Strong debugging, code-review, documentation, and stakeholder communication skills.
• Ability to work independently and collaboratively across multiple concurrent engagements and manage priorities.
• DoW 8140 aligned IAT Level II certification, with Security+ CE or an approved equivalent.
• Active Top Secret security clearance required. Candidates must be eligible to obtain and maintain any additional customer-specific access requirements associated with their assigned work.

Preferred Qualifications

• Active TS/SCI security clearance.
• Direct experience delivering applications in Azure Government, Azure Government Secret, Azure Government Top Secret, GCC High, or another classified or highly regulated environment.

• Experience developing with approved AI tools in regulated, disconnected, air-gapped, or restricted environments.
• Experience with CAC/PIV authentication, DoD PKI, RMF, FIPS requirements, DoD IL5 or classified workloads, and DISA STIGs.
• Experience with Vitest or Jest, Supertest, Playwright, axe-core, or comparable automated testing tools.
• Experience with Docker, AKS, OpenShift, Kubernetes, and hardened container images such as DoD Iron Bank images.
• Experience with C#/.NET, Java, Go, or Python in addition to Node.js.
• Microsoft certifications related to Azure development, architecture, security, or data.
