Job description

C5MI is not your typical consulting firm. We are a high-performance team of SAP and supply chain experts who solve complex, mission critical challenges for organizations that cannot afford failure.

We hire consultants who thrive in complexity, move fast, take ownership, and deliver under pressure. At C5MI, you will not be siloed or stuck in theory. You will be hands on, client facing, and directly influencing outcomes that matter.

Our culture rewards initiative, accountability, and continuous growth. This is a place where your expertise is valued, your work is meaningful, and your performance truly matters. If you’re energized by learning through real-world challenges, collaborating with top-tier talent, and expanding your capabilities every day, C5MI is where strong consultants level up.

The Lead Solution Architect is the single technical design authority for a large-scale, greenfield SAP S/4HANA financial management modernization program for a Department of War (DoW) organization, accountable for the integrity, coherence, and deliverability of the end-to-end solution across all nine financial process areas. This position leads the program’s architecture function, directing process area solution architects and partnering with cloud, data, and platform architecture leadership to ensure a unified target architecture built on a fit-to-standard, clean-core approach. The Lead Solution Architect chairs architecture governance, approves or rejects design decisions and extension requests, resolves cross-process-area design conflicts, and is accountable to government leadership for the technical defensibility of the delivered solution at every milestone gate.

Note: This position is contingent upon contract award.

Essential Functions and Responsibilities:

• Owns the end-to-end target solution architecture spanning core finance, budgetary execution, asset accounting, payables and receivables, managerial cost accounting, inventory, financial reporting, integration, and legacy data transition.

• Chairs the program architecture review board; establishes design principles, solution patterns, naming and configuration standards, and the decision record process.
• Enforces a fit-to-standard, clean-core delivery posture; adjudicates every request for custom development or extension against standard and pre-delivered federal content, and documents the rationale for approved deviations.
• Directs design of the single, standards-aligned chart of accounts and financial data model, ensuring every financially relevant event posts to a single, immutable, auditable document chain.
• Governs integration architecture across the financial core, the low-code extensibility layer, analytics and reporting platforms, and interfacing logistics, procurement, and personnel domains.
• Owns non-functional requirements, including performance, scalability, availability, recoverability, and resilience in denied, degraded, intermittent, and limited-bandwidth operating conditions.
• Serves as the senior technical authority in milestone gate reviews, presenting and defending the architecture at preliminary design review, critical design review, and production readiness review.
• Partners with security and risk management framework leadership to ensure the architecture is authorizable, inherits available control sets, and sustains its authority to operate through change.
• Reviews and approves functional and technical design documentation produced across delivery teams, ensuring traceability from requirement to design to test.
• Establishes the technical debt and architectural runway strategy, balancing near-term milestone delivery against long-term sustainment and upgrade cost.
• Mentors solution architects and senior functional leads, building enterprise architecture capability across the program and the broader C5MI delivery organization.
• Advises program and government leadership on solution trade-offs, sequencing options, and the technical implications of scope and schedule decisions.
• Ability to travel up to 50% to client sites, varying based on client program schedules.
