[Remote] Appian Integration Engineer

Note: The job is a remote job and is open to candidates in USA. ICF is an information technology and management consulting company that provides strategic solutions and high-performance IT services to public- and private-sector clients. The Appian Integration Engineer will own the integration and data-migration layer for a federal case management modernization, designing secure API-based integrations, leading legacy application migration, and ensuring data quality, monitoring, and traceability.

Responsibilities

• Design and build inbound and outbound integrations in Appian — Connected Systems, Integration objects, Web APIs, and synced record types — against REST and SOAP services, using API keys, OAuth 2.0, and service accounts appropriately
• Establish the integration patterns the team builds to: incremental (watermark) synchronization, idempotent upserts, retry and back-off, correlation IDs, reconciliation queues for changes that cannot be applied automatically, and per-run audit logging
• Produce and maintain API contracts and interface control documents; work directly with system-of-record owners to obtain, validate, and align to their API documentation and test environments
• Lead the migration out of a legacy .NET/SQL Server application: data profiling, source-to-target mapping, transformation and cleansing, validation and reconciliation, cutover planning, and migration of its reports to Power BI
• Implement data-quality checks, validation, monitoring, and traceability so integration health is visible in the client's enterprise monitoring tools and failures are actionable
• Tune integration and data-movement performance against defined service levels for response time, error rate, and availability
• Build within a DevSecOps pipeline (source control, automated tests, code quality scanning) and contribute integration test coverage
• Collaborate with the Appian architect, developers, testers, data governance personnel, and government subject-matter experts in an Agile (Scrum) delivery team

• Hands-on experience building integrations and/or Web APIs in Appian (Connected Systems, Integration objects, Web API objects, record types) in at least one delivered project. Appian certification is not required
• Strong SQL skills and experience migrating data out of relational systems, including source-to-target mapping, transformation, validation, and reconciliation
• Bachelor's degree in a related field; directly related experience may be considered in place of education
• Experience with Microsoft SQL Server and with modernizing or decommissioning .NET applications
• Experience integrating with federal HR systems of record (for example, USA Staffing, HR Connect, or similar OPM/Treasury shared services)

• Experience with OpenAPI/Swagger, API gateways, and API security practices (OAuth 2.0, key management, mTLS)
• Scripting or programming in at least one of Python, Java, or JavaScript for transformation, testing, or automation
• Familiarity with CI/CD and quality tooling such as GitLab, Jenkins, SonarQube, and JMeter, and with log/monitoring platforms such as Splunk
