SAP S/4HANA Data & Integration Engineer

Info-Matrix Corporation•Harrisburg, PA

2d•Onsite

About The Position

Our client is building a hands-on SAP S/4HANA data and integration capability to support public-sector transition programs that retire legacy, flat-file interfaces in favor of modern SAP S/4HANA APIs, data services, and Okta-based identity. You will be the engineer who reads SAP S/4HANA data structures, maps legacy data to them, and helps agency and delivery teams stand up secure, modern integrations — working alongside client and SAP technical leads. This role directly addresses the data-mapping, API/integration, and reporting workstreams at the heart of Commonwealth SAP modernization work.

Requirements

5+ years of hands-on SAP integration/data engineering, including demonstrable, project-based SAP S/4HANA experience (not functional-config only).
SAP S/4HANA data structures — working fluency with the S/4HANA data dictionary, tables, and CDS views, and consuming S/4HANA OData/REST APIs.
SAP integration & data platforms — hands-on with one or more of: SAP BTP / SAP Integration Suite (Cloud Integration), SAP Datasphere / SAP data lake, SLT / data replication.
Data mapping & API integration — field-level source-to-target mapping, transformation logic, REST/OData, OpenAPI/Swagger, and secure integration patterns (OAuth2 / mTLS).
U.S.-based and able to attend onsite, in-person meetings in Harrisburg, PA when requested (all work performed within the United States).

Nice To Haves

Okta (identity/provisioning) — hands-on Okta provisioning, SCIM, lifecycle management, and attribute mapping. A candidate who covers BOTH SAP S/4HANA integration and Okta is ideal.
SAP HCM / SuccessFactors — experience with SAP HR/employee-data structures (the source data in these transitions is HR data).
Public-sector delivery — state or Commonwealth of Pennsylvania IT experience; comfort in multi-agency, governed, wave-based delivery environments.
Clearance eligibility — able to obtain and hold a U.S. Public Trust.

Responsibilities

Data mapping & transformation analysis — compare legacy source fields against SAP S/4HANA data structures (tables, CDS views, data dictionary); identify gaps, misalignments, and required transformations; produce field-level mapping workbooks, data dictionaries, and IRIS-to-SAP-style crosswalks.
API & integration design — design, configure, and validate integrations against SAP S/4HANA APIs (OData/REST), SAP BTP / Integration Suite, and SAP data lake / Datasphere; support the move from flat-file patterns to modern, secure API-based solutions, including data-contract validation and environment readiness.
Hands-on troubleshooting — review and resolve end-to-end integration workflows with agency developers and SAP/IESO technical leads; support alternative patterns (e.g., middleware) where systems cannot yet consume APIs.
Identity / provisioning support (Okta) — support user-provisioning transitions to Okta — HR-attribute mapping, SCIM/provisioning logic, and group rules — sourcing employee identity data from SAP. (Strongly preferred; see qualifications.)
Documentation & enablement — produce API set-up guides, example payloads, technical walkthroughs, data validation checklists, and integration-readiness templates that let agency teams self-serve.
Testing, cutover & hypercare — support test planning, data-continuity validation, cutover readiness, and post-go-live stabilization.
