MAS Global is hiring a Principal Finance SME with deep, hands-on Rebates & Incentives (R&I;) experience to be the finance lead on our AI-first transformation programs for large financial services and payments clients in the US. This is a long-term, full-time position.

You'll be embedded in client process workshops from day one, challenging how deals, accruals, payments, reconciliations and controls work today, and turning that into sized AI opportunities in hours and dollars that the client's Finance owners will sign off. You'll work beside an AI Solution Architect, a Data & Integration Architect and a Senior Delivery Manager.

This is not a generic finance-transformation role. You must have run or redesigned a contract-driven incentive or rebate process at enterprise scale, and be credible in a room of Controllers, Accounting and Sales Ops leaders.

About the work

MAS General helps enterprise Finance organizations find where AI, automation, agentic workflows and digitized deal data create measurable ROI, then move the best opportunities from concept to MVP and scale.

- Process focus: the end-to-end R&I; lifecycle: contract drafting, deal intake and setup, actualization, accounting, payments, reconciliations, close, controls, audit support and reporting.
- Model: co-creation. Clients lead their process workshops; MAS runs its Compass method alongside them and owns the evidence, value sizing and MVP design.
- Outputs: AI opportunity inventories, quantified value maps and investment cases, build / buy / configure recommendations, MVP-level designs, and support through implementation.
- Team: small cross-functional teams of AI, data, delivery and finance specialists, backed by MAS nearshore engineering in LATAM.

Key responsibilities

Discovery

- Act as embedded finance advisor in client-led walkthroughs: question assumptions, spot manual work, leakage and control gaps as each step is documented.
- Log every opportunity with its process step, owner, frequency and current cost in time.
- Collect the evidence behind each one: CBAs, deal samples, accrual and reconciliation workbooks,



close checklists, control narratives.
- Build the value hypothesis for each opportunity in hours and dollars, keeping costs separate, and get it confirmed by the client's Finance owners.

Define and design

- Score opportunities for impact and readiness (Reach × Impact × Confidence ÷ Effort) with the architects.
- Own the finance content of the quantified value map and executive investment case, and defend its assumptions with Controllers and FP&A.;
- Specify business rules for MVP candidates such as clause extraction from CBAs, a single actualization engine across regions, reconciliation explainers, payment request checks and close exception ranking.
- Design future-state controls with the team: approval flows, segregation of duties, audit evidence, and named human sign-off for agent-generated work.
- Define measurable success criteria per MVP: manual touch time, cycle time, exception and rework rate, close effort, audit evidence preparation time.

Throughout

- Translate between Finance and the technical team so data and API contracts reflect real accounting treatment (accruals, true-ups, revenue offsets, contra-revenue).
- Represent MAS in weekly checkpoints and monthly scorecards; help keep open decisions under 5 business days.
- Stay with programs into build, testing and adoption as finance product owner support, and bring the approach to new clients and engagements.

Required qualifications

- 12+ years in Finance, with 5+ years owning, operating or redesigning a rebates, incentives, customer incentive or channel/partner incentive process at a large enterprise (payments, card networks, banking, fintech, telecom, CPG or high tech).
- End-to-end knowledge of the lifecycle:



contract terms to deal setup, volume actualization, accruals and true-ups, payments, reconciliations and month-end close.
- Strong technical accounting grounding: ASC 606 treatment of consideration payable to a customer, contra-revenue, accrual estimation and reversal.
- Hands-on experience with controls and audit: SOX / ICFR, control design, evidence requests from internal and external auditors.
- Proven record building business cases and value models that Finance leadership signed off (driver-based, hours and dollars, with sensitivities).
- Has led or been a core member of at least one finance transformation or automation program (ERP, RPA, workflow, contract management or AI).
- Working literacy in AI and automation use cases for Finance: document and clause extraction, rules engines, agentic workflows, exception triage. Not a developer, but able to shape requirements with architects.
- Executive presence: comfortable challenging VPs and Controllers in a workshop and presenting to a CFO-level audience.
- Fluent professional English, written and spoken, for daily work with US-based clients.
- Bachelor's degree in Accounting, Finance or Economics.

Preferred qualifications

- CPA, CMA, ACCA, Contador Público or equivalent; MBA a plus.
- Direct experience at a card network, issuer, acquirer or processor, or on customer incentive agreements with financial institutions or merchants.
- Background at a Big Four or top-tier consultancy in Finance Transformation or Risk & Controls, combined with years in an industry role.
- Experience with multi-region incentive programs where each region runs its own calculation workbook.
- Familiarity with SAP S/4HANA or Oracle Financials, and with revenue or incentive management tools (e.g., Vistex, Model N, Zuora, Salesforce CPQ/CLM).
- Prior work defining MVPs, user stories or acceptance criteria in an agile team.
- Exposure to model risk or AI governance reviews in a regulated company.
- Experience working with US-based Finance teams or clients.
