About the Role

• COMPA Industries is recruiting on behalf of Los Alamos National Laboratory (LANL) for a Solutions Architect 4 – SAP S/4HANA Data Migration Lead supporting Project Nexus and LANL's broader enterprise data modernization initiative.
• LANL is moving its enterprise resource planning environment to a cloud-based SAP platform, including a greenfield S/4HANA implementation. Ariba, Concur, and Fieldglass are already part of the broader SAP ecosystem, and the future-state data architecture will include SAP Business Data Cloud connected to Databricks.
• This role will serve as LANL's internal senior authority on SAP data migration. The selected candidate will oversee, evaluate, and challenge the System Integrator's recommendations while helping LANL make the right decisions regarding migration architecture, data quality, cost, risk, governance, cutover, and long-term operational impact.
• The ideal candidate is not a passive reviewer. This person must be able to translate highly technical migration guidance into practical, actionable decisions for LANL leadership and delivery teams. The role requires someone who can identify unnecessary risk, prevent runaway costs, and ensure that short-term implementation choices do not create long-term operational burdens.
