Web Developer | Active Secret clearance

Full-Stack Web Application Developer

Transform technology into opportunity as a Web Developer at GDIT. Shape what's next for mission-critical government projects while shaping what's next for your engineering career.

As a Full-Stack Web Application Developer supporting the Shipboard Advanced Tactical Data Link Engineering Support program, you will:

• Analyze the existing Microsoft Access-based TEDB application and document its current functionality.
• Inventory existing Access forms, subforms, queries, reports, macros, navigation panels, data-entry paths, and workflow rules.
• Identify undocumented or hidden logic contained within Access macros, queries, form events, and application settings.
• Work with the TEDB Database Engineer, Test and Evaluation personnel, system engineers, Navy users, and other subject-matter experts to understand operational requirements.
• Develop end-to-end process maps documenting existing TEDB workflows.
• Develop and maintain an Entity Relationship Diagram for the TEDB SQL database.
• Map each existing Access feature and workflow to its corresponding implementation within the modernized web application.
• Document data inconsistencies, unsupported practices, or workflow risks discovered during analysis.
• Ensure existing workflows are preserved unless changes are reviewed and approved by the appropriate government stakeholders.

Application Architecture and Design

• Support definition of the web application architecture, including the front-end framework, backend services, API structure, authentication approach, reporting strategy, and deployment model.
• Develop wireframes, interface mockups, prototypes, user workflows, and technical design documentation.
• Design the application for scalability, maintainability, cybersecurity compliance, and long-term lifecycle support.
• Develop reusable application components that can support multiple TEDB implementations and Tactical Data Link product areas.
• Support architecture and design reviews with technical and government stakeholders.
• Coordinate with cybersecurity personnel to ensure application architecture supports applicable Federal, DoW, Department of the Navy, DISA, and command cybersecurity requirements.

Front-End Development

• Design, develop, test, and maintain a responsive React-based web application.
• Reimplement Microsoft Access forms as browser-based data-entry and data-management interfaces.
• Reimplement Access subforms as relational parent-and-child views.
• Develop API-driven navigation, search, filtering, and SQL-backed data views.
• Develop dynamic user-interface components, including cascading dropdowns and conditional field behavior.
• Implement inline editing through editable grids and table components.
• Develop multi-record views, data tables, dashboards, reports, risk displays, and requirements traceability views.
• Develop intuitive interfaces that allow users to search, filter, sort, navigate, update, and analyze complex Test and Evaluation data.
• Implement application state management using Redux, Redux Toolkit, React Context, or a comparable approach.
• Ensure interfaces are responsive and usable across approved browsers and workstation configurations.
• Incorporate user feedback while minimizing unnecessary disruption to established TEDB workflows.

Backend and API Development

• Design, develop, document, test, and maintain backend application services and REST APIs.
• Migrate macro-based business logic into the application and API layers.
• Implement field validation, automated updates, conditional logic, workflow rules, and error handling.
• Replace Access saved queries with secure API endpoints, optimized SQL queries, database views, or stored procedures.
• Integrate the application with the existing TEDB SQL database backend.
• Support controlled database-schema evolution where required to meet approved application objectives.
• Maintain separation between presentation, business-logic, API, and database layers.
• Develop secure and maintainable services supporting data creation, retrieval, update, reporting, and authorized administrative functions.
• Ensure system performance meets or exceeds the capabilities of the current Access implementation.

Authentication and Cybersecurity

• Support integration of the application with the government-approved authentication and authorization solution.
• Implement or integrate role-based access controls for authorized internal and external users.
• Support Federal authentication requirements involving identification, identity verification, multifactor authentication, phishing resistance, FIPS-validated technologies, and secure session management.
• Apply secure software development practices throughout design, development, testing, and deployment.
• Support cybersecurity documentation, vulnerability remediation, code scanning, dependency management, and authorization activities.
• Work with cybersecurity and infrastructure personnel to address security controls without disrupting required operational workflows.
• Protect the confidentiality, integrity, and availability of TEDB data.

Reporting and Data Presentation

• Preserve current TEDB reporting capabilities while supporting future reporting expansion.
• Reimplement current Access reports within the web application, SQL environment, or an approved enterprise reporting capability.
• Support reports associated with requirements, test procedures, test cases, test observations, Test Observation Reports, risks, results, and requirements traceability.
• Develop exports and formatted data products required by Test and Evaluation personnel and program stakeholders.
• Support integration with SQL Server Reporting Services or another approved reporting platform when selected.
• Validate report output against the existing TEDB application.

Testing and Validation

• Develop unit, component, integration, regression, API, and database tests.
• Conduct side-by-side comparison of the Access and web-based TEDB implementations.
• Validate forms, workflows, calculations, automated updates, queries, reports, and business rules.
• Support User Acceptance Testing with Navy users and Test and Evaluation personnel.
• Conduct data validation to ensure that the modernized application preserves data accuracy and integrity.
• Identify, document, prioritize, and resolve software defects and data discrepancies.
• Develop repeatable testing processes and environments.
• Maintain software test results and traceability to approved functional requirements.

Deployment, Transition, and Lifecycle Support

• Support development of the application deployment, cutover, training, and transition strategies.
• Develop user guides, training materials, Standard Operating Procedures, administration guides, and technical documentation.
• Support deployment of the application into approved Navy environments.
• Assist with transition from the Access front end to the web-based application.
• Support controlled decommissioning of the Access front end after validation and government approval.
• Provide post-deployment troubleshooting, maintenance, performance optimization, and feature enhancements.
• Support application configuration management, source control, release management, and continuous integration activities.
• Maintain system architecture, API, database, workflow, and sustainment documentation.

Program and Team Collaboration

• Work directly with Navy users to understand requirements, demonstrate capabilities, and incorporate approved feedback.
• Participate in sprint planning, daily standups, code reviews, design reviews, technical exchanges, and user demonstrations.
• Collaborate with database engineers, software developers, system engineers, Test and Evaluation engineers, cybersecurity personnel, infrastructure teams, and government stakeholders.
• Independently own assigned features from requirements analysis through deployment and sustainment.
• Communicate technical risks, dependencies, alternatives, and recommendations clearly to technical and nontechnical stakeholders.
• Support Shipboard Link 16, Command and Control Processor Modernization, MIDS on Ship, Link 22, and other Tactical Data Link requirements and Test and Evaluation data efforts.
