Trace business rules, calculations, transformations, data access, authentication, error handling, and external dependencies in legacy code.

Develop API facades and compatibility adapters that preserve external contracts while target Appian capabilities transition.
Refactor approved services into modular, testable components or bounded external services where Appian-native implementation is not appropriate.
Eliminate unsupported libraries, embedded credentials, obsolete protocols, and high-risk custom code through approved designs.
Create unit, integration, contract, regression, and security tests that compare modernized behavior with the legacy baseline.
Support data migration, parallel operation, deployment, cutover, rollback, stabilization, and legacy retirement.
Package code through the approved DevSecOps pipeline and resolve code-quality, dependency, vulnerability, and licensing findings.
Maintain technical designs, interface specifications, dependency maps, release notes, and operational documentation.

Education and Experience Required:

Bachelor's degree in computer science, engineering, information systems, or a related field; additional relevant experience may substitute for education.
Five or more years of enterprise software engineering experience using Java, .NET/C#, or both.
Experience modernizing legacy applications, decomposing tightly coupled services, and preserving APIs, business rules, and data behavior.
Experience with relational databases, REST/SOAP services, secure coding, automated testing, CI/CD, and production troubleshooting.
U.S. citizenship and the active security clearance or eligibility required for the assigned work by the start of performance, with ongoing eligibility thereafter.
Ability to communicate clearly with Government, technical, and business stakeholders and to maintain accurate work records in approved systems.
Ability to protect Controlled Unclassified Information and classified information, when assigned, and comply with required access, training, and handling procedures.

Education and Experience Desired:

Experience integrating conventional code with Appian or another low-code platform.
Experience with Spring, ASP.NET, containers, AWS, Oracle, S3, or enterprise document and reporting systems.
Experience modernizing Federal acquisition, financial, or other regulated applications.

Required Skills and Competencies:

Java and .NET enterprise development
Legacy analysis and incremental refactoring
API facades and compatibility engineering
Automated testing and secure DevSecOps
Migration, cutover, and production support

Work Environment and Travel:

Work may occur remotely when authorized, at Government facilities, or in controlled office and data-center environments. Work involving classified information or SIPRNet will be performed at a Government-approved secure location using authorized systems. The role generally supports Government business hours, with occasional release, incident-response, maintenance-window, or approved travel requirements. Reasonable accommodations may be made to enable qualified individuals with disabilities to perform the essential functions.
