SAP OTC Architect

Tessera Labs

1d•$150,000 - $200,000

About The Position

Tessera Labs is seeking an SAP Order-to-Cash Architect to own the OTC domain across multiple customer engagements concurrently. The role focuses on the flow from lead and order capture through pricing, availability, delivery, billing, and cash application, including the customer-specific development accumulated around those processes. Most engagements involve ECC-to-S/4HANA transformation. The architect assesses whether existing customizations reflect genuine business requirements or historical workarounds, then designs an appropriate conversion path—brownfield, selective data transition, or greenfield—and explains its costs and trade-offs. The architect works with Tessera’s AI agents and platform, applying business and architectural judgment to decisions the platform cannot make independently. Field expertise and lessons are fed back into platform checks, patterns, rules, and accelerators. The role is measured by durable target-state OTC designs that customer architects support and that sales operations, logistics, and billing teams actually adopt. The position spans OTC solution ownership; ECC-to-S/4HANA assessment and conversion architecture; platform enablement and product input; and customer adoption and knowledge transfer. It includes coordinating with Forward Deployed Engineers, customer architects, Technical Program Managers, the Principal Architect, and distributed delivery teams, as well as supporting pre-sales on SAP opportunities with an OTC component.

Requirements

12+ years of SAP experience centered on order-to-cash, including architect-level ownership on at least two full-lifecycle implementations, conversions, or transformations.

Practical command of at least one S/4HANA transition approach—brownfield conversion, selective data transition, or greenfield—and an informed understanding of why a customer might choose another approach.
Familiarity with readiness and pre-check tooling, custom code analysis, and realistic high-volume OTC cutover windows.
Command of the OTC data model and integration surface, including sales, delivery, billing, and pricing tables and document flow; customer master and Business Partner conversion; IDoc and EDI flows; and enhancements and user exits.
Fluency in the business processes behind OTC configuration, including pricing and discounts, credit and blocks, third-party and intercompany flows, returns, rebates, revenue recognition, billing, disputes, and collections.
