SAP OTC Architect

Role details

ABOUT TESSERA LABS Tessera is an AI-native platform for enterprise transformation. The multi-agent platform delivers governed execution across ERP, CRM, HCM, and finance systems, cutting timelines from years to weeks and costs by more than half. Built on deep expertise across Oracle, SAP, Salesforce, Workday, and other systems of record, Tessera address the scope a system integrator would have traditionally taken up with the speed of execution and efficiency of an AI-native platform. For decades, enterprises have struggled with fragmented business systems, where migrations have consumed hundreds of millions of dollars, data stayed inconsistent and unreliable, and business processes slowed under manual review. Tessera was founded to change that, for SAP and every other system enterprises depend on. The name itself — a tessera, a single tile in a mosaic — reflects our mission: unifying the disparate pieces of the enterprise into a coherent whole. Tessera is an AI-powered, multi-agent platform that harmonizes systems and lets teams work in plain English. ROLE SUMMARY We are looking for an SAP Order-to-Cash Architect to own the OTC domain across several customer engagements at the same time. This is a specialist role, and that is deliberate. Our Principal Solution Architects hold the whole solution; you hold the part of it that most often decides whether a program lands on time — the flow from lead and order capture through pricing, availability, delivery, billing and cash application, and the twenty years of customer-specific development sitting on top of it. Most of this work is ECC to S/4HANA. Customers come to us with order-to-cash estates built up since R/3: pricing routines nobody will touch, user exits in MV45AFZZ that encode rules no one wrote down, custom order types that exist because of a reorganization in 2011, and an output determination setup that only works because of a Z-program. The job is to tell the difference between a genuine business requirement and an accident of history, and to architect the conversion on that basis — brownfield, selective data transition, or greenfield, and clear-eyed about what each one costs. You will do that work with Tessera’s AI agents, not instead of them. The platform handles the custom code inventory, the simplification item analysis, the data profiling and a large share of the conversion and reconciliation work. What it cannot do is decide whether a customer genuinely needs four hundred condition tables, or which of six sales document types survives the move. That judgment is the role. Every time you exercise it, we expect it to go back into the platform so the agents are better at it on the next engagement. Two outcomes define the job. The first is a target-state order-to-cash design the customer’s own architects will defend after we step back. The second is that their sales operations, logistics and billing teams use what we built rather than rebuilding the workarounds they had before. The second is what makes the first durable, and it is the measure you will be held to. KEY RESPONSIBILITIES 1. ORDER-TO-CASH SOLUTION OWNERSHIP (40%) - Own the functional and architectural direction of the order-to-cash domain on several concurrent engagements — Sales, Pricing, Availability, Logistics Execution, Billing and Accounts Receivable, together with the credit, tax, revenue and collections processes that hang off them. - Design the target state and the route to it, including the trade-offs between what the customer asked for, what their current system does, and what will actually create value. - Set the standard for the build: review functional specifications, define the conversion, reconciliation and cutover approach for OTC data and open documents, and hold architectural integrity through delivery rather than signing off and leaving. - Work directly with Forward Deployed Engineers, Tessera AI agents and customer architects, and be the person who can answer an OTC question without scheduling a follow-up. - Own the integration surface out of OTC — EDI and IDoc flows, tax engines, payment and banking, CRM and commerce front ends, transportation and warehouse systems, downstream finance — and say early when a dependency will not hold. - Be the counterpart our Technical Program Managers come to first on order-to-cash, and get a straight answer from. 2. ECC TO S/4HANA ASSESSMENT AND CONVERSION ARCHITECTURE (25%) - Lead order-to-cash discovery on ECC estates: custom code and enhancement inventory, interface mapping, data quality, process debt, and what each of those is costing the business today. - Own the SD-relevant simplification items end to end — credit management moving to SAP Credit Management, rebates to Settlement Management, SD revenue recognition to Revenue Accounting, foreign trade to GTS, output management to BRF+, the retired status and pricing structures — and translate each into scope, effort and risk rather than a list. - Separate requirement from habit. Produce a defensible recommendation on what carries forward as standard, what is genuinely differentiating, and what should be retired — particularly across pricing procedures, order types, item categories and copy control. - Architect the transition path — system conversion, selective data transition or new implementation — and be clear about where each one hurts for a high-volume OTC estate. - Own the OTC data story, including the customer master and Business Partner position that gates any conversion: sold-to, ship-to and payer relationships, partner determination, open orders, open deliveries and open receivables, through to conversion design and reconciliation. - Make the case, with evidence, when a customer’s plan will not survive contact with their own data. 3. PLATFORM ENABLEMENT AND PRODUCT INPUT (20%) - Contribute your order-to-cash domain know-how back into the Tessera platform, so the agents get better at this work with every engagement. - Turn what you find in the field into
