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
