CACI’s Financial ERP division is seeking a Senior SAP Solution Architect to lead enterprise modernization across mission‑critical federal programs. In this senior role, you will shape technical strategy and steer solution architecture for complex SAP S/4HANA & BW/4HANA landscapes, while driving integration with enterprise platforms such as Salesforce, ServiceNow, SharePoint/O365, and cloud services (AWS/Azure). You will partner with program leadership and Agile/SAFe delivery teams to ensure solutions are scalable, secure, compliant, and aligned to agency mission outcomes. You will provide vision and leadership across all phases of program delivery—from inception through sustainment—and will advise on enterprise business, information, and technology strategy to ensure solutions are scalable, compliant, secure, and aligned with agency goals.
• Establish SAP enterprise architecture principles and guardrails with reference architectures for S/4HANA, BW/4HANA and ensure alignment with agency strategies and enterprise platforms (Salesforce, ServiceNow, SharePoint/O365). Focus on standards and approvals—not day‑to‑day management.
• Own the portfolio‑level S/4HANA strategy and modernization roadmap across a large scale federal program, sequencing Explore/Realize activities and mapping cross‑program dependencies; publish quarterly roadmap updates.
• Chair the program Architecture Review Board (ARB) and approve patterns, interface contracts, data standards, and security controls; maintain the decision log; ensure compliance with FISMA/NIST and agency policies.
• Set the integration strategy spanning ERP, SCM, analytics, case/workflow, and cloud (AWS/Azure); codify API/eventing patterns (IDoc/OData/REST), integration security, and observability requirements; conduct targeted design reviews.
• Direct the data strategy for S/4 including Business Partner CVI conversion, DVM/readiness checks, BW/4HANA upgrades, and analytics enablement (SAC/BOBJ); establish data quality and lineage guardrails via a federated data council.
• Oversee portfolio metrics & OKRs for architecture health, technical debt, risk posture, and value realization; partner with APMO for data‑driven decisions and transparent reporting; publish a quarterly posture dashboard.
• Guide vendor/SI solution architecture evaluations; set technical entry/exit criteria, ensure adherence to patterns, and escalate design issues when risk or complexity warrants.
• Lead legacy rationalization—deprecate, upgrade, or replace systems to reduce technical debt and accelerate modernization; maintain a living rationalization plan.
• Conduct senior stakeholder briefings with agency leadership to communicate architecture trade‑offs, risk mitigations, and mission impacts; maintain decision logs.
• Sponsor Communities of Practice and pattern libraries; curate reusable artifacts and provide office hours to upskill delivery teams without direct line management.
