Solutions Architect

Role Description

SMSI LLC is seeking a Solutions Architect (SAP S/4HANA Data Migration Lead) to assist our client, Los Alamos National Laboratory (LANL). This position supports Project Nexus, LANL’s large-scale enterprise modernization initiative. The Solutions Architect will serve as the client-side Data Migration Lead and senior technical authority for the migration of legacy enterprise data into SAP S/4HANA. This position will be remote with short term travel as needed.

• Combine deep SAP S/4HANA data migration leadership with working knowledge of SAP Business Data Cloud and Databricks or a comparable enterprise data platform.
• Serve as the client-side senior authority on SAP data migration; face off to the System Integrator's data lead as a technical peer.
• This is a hands-on senior advisory position; must be comfortable independently challenging System Integrator recommendations while managing daily plans, working sessions, actions, risks, data-quality activities, mock loads, reconciliation, and cutover readiness.
• Review and challenge the SI's data migration approach and push back where the approach carries unnecessary risk, cost, or downstream operational burden.
• Advise the program on migration architecture decisions specific to greenfield S/4HANA from non-SAP sources (Oracle EBS, JD Edwards, PeopleSoft, custom systems), including source-to-target data model translation and legacy-concept-to-SAP-concept mapping.
• Advise on tooling selection when the SI's approach is still open and evaluate trade-offs on fit, cost, timeline, and regulated-industry auditability.
• Own day-to-day execution coordination of the client-side data workstream across all domains.
• Keep the migration task plan current, flag slippage early, and drive resolution.
• Serve as the daily point of contact with the SI's data migration team; track integrator deliverables and escalate delays.
• Run regular working sessions with client data owners and the integrator's team; chase open actions, decisions, and deliverables between meetings.
• Set and monitor cleansing standards across data domains against agreed quality thresholds; validate that the SI's quality criteria are fit for S/4HANA go-live.
• Coordinate with business data owners to keep cleansing on schedule; unblock issues with the right people rather than deferring upward.
• Surface data quality risks the SI may not flag (missing legacy concepts, silent data loss in transformation, dependencies across domains) before they become critical.
• Organize and track mock load cycles across all domains.
• Review reconciliation results independently of the SI.
• Ensure business teams complete validation tasks within cycle windows and that findings are actioned.
• Ensure data migration activities comply with the organization's data classification policy and applicable regulatory requirements throughout extraction, staging, transformation, and load.
• Maintain the data migration cutover plan; coordinate extraction and load scheduling with the SI and technical teams.
• Prepare data readiness inputs for go/no-go decisions and provide informed, independent risk assessment to program leadership.
• Support hypercare on data-related issues post go-live.
• Support migration status reporting and RAID logging for program leadership.

Qualifications

• 15+ years of enterprise SAP and data migration experience, including leadership of multiple full-lifecycle S/4HANA data migration programs. Four completed programs are strongly preferred (greenfield preferred).
• Experience running the data workstream from inside a major System Integrator on programs of significant scale and complexity, followed by client-side advisory work.
• Deep hands-on experience migrating from non-SAP sources into SAP.
• Full-scope enterprise migration experience spanning Finance (FI/CO), Supply Chain (MM, SD, PP, WM), HR/HCM, Plant Maintenance / EAM, and Master Data (business partner, material, customer, vendor).
• Working expertise across multiple migration toolsets.
• Demonstrated focus on delivery quality.
• Comfortable engaging SI leadership as a peer: knows when to escalate, when to accept an SI's judgment, and when to hold position; can distinguish genuine constraints from convenient ones.
• Hands-on advisor: runs working sessions, chases actions, maintains plans day-to-day, and retains senior-level judgment throughout.
• Deep understanding of S/4HANA data models, business partner concept, universal journal, material ledger, and the structural changes from legacy ERPs.
• Strong grounding in data migration methodology: ETL design, staging strategies, reconciliation, cutover sequencing, fallback planning, and hypercare data support.
• Regulated-industry experience with hands-on exposure to at least one of HIPAA, SOC 2, PCI-DSS, GDPR, FedRAMP, or comparable frameworks. Demonstrated ability to translate compliance requirements into data migration controls.
• Excellent written and verbal communication; can move fluidly from executive readouts to deep technical review with the SI's data engineers.
• Must be a US Citizen.

Preferred Qualifications

• Prior experience specifically with Oracle EBS as the source system.
• Familiarity with SAP Business Data Cloud (BDC) and its role in S/4HANA data landscapes.
• Experience with Databricks, Snowflake, or comparable enterprise data platforms used for migration staging, transformation, data-quality analysis, reconciliation, lineage, audit support, or integration with SAP data environments. Direct Databricks experience is strongly preferred.
• SAP certifications (S/4HANA, Data Migration, or comparable).
• Experience in regulated environments beyond baseline compliance — audit-heavy sectors such as financial services, healthcare, life sciences, pharma, or government.

Education Requirements

• Bachelor’s degree in information technology, computer science, engineering, data management, business information systems, or a related field, plus at least 15 years of directly relevant experience. Extensive and highly relevant SAP S/4HANA data migration experience may be considered in lieu of the degree requirement.
