Senior Manager, Supplier Enablement & Spend Conversion

Responsibilities

• Build the Spend Conversion function from the ground up, defining the strategy, entry criteria, engagement model, and KPIs for converting non-card vendor spend to Brex.
• Envision a holistic approach involving key parties and operations from Capital One as well as 3rd party vendors.
• Own the end-to-end vendor spend migration motion, from vendor-file analysis and card-acceptance identification through negotiation and card activation.
• Partner cross-functionally with product, implementation, BD, and sales to bring these workflows to market, and to grow our acceptance database through data partnerships, not just outreach.
• Advise enterprise customers directly, unlocking spend with their most strategic vendors and translating their goals into concrete migration and negotiation plans.
• Design a differentiated, AI-native approach to supplier enablement rather than replicating the manual playbook legacy issuers rely on.
• Establish the operational rigor (tracking, reporting, and incentive structures) that makes the function measurable and scalable.
• Hire and coach a team of specialists as the function proves out, operating as a player-coach in the early phase.
• Champion spend conversion internally, educating stakeholders and shaping how Brex captures share-of-wallet across its customer base.

Requirements

• 5+ years in B2B/commercial card, payments, supplier enablement, or vendor/payment operations, deep enough to shorten the learning curve, rather than learning the domain on the job.
• Demonstrated experience building a function or program from 0-to-1 (or scaling something early and unstructured), standing up processes, KPIs, and operating cadences where little existed.
• Working knowledge of card acceptance and merchant economics: how vendors process cards, card-on-file vs. card-per-invoice, fees, and the buyer/supplier trade-offs (e.g., DSO/DPO, cash flow).
• Proven ability to negotiate and influence, with vendors on acceptance terms and internally across executives and functions.
• Direct customer-facing experience with enterprise customers; comfort owning senior relationships and turning customer goals into execution.
• A first-principles, builder mentality: you create the vision and drive it forward through ambiguity rather than waiting for a playbook.
• Track record as a cross-functional operator who has shipped alongside product, sales/BD, and implementation.
• A leadership foundation: you've led people or major initiatives and are ready to build and manage a team over time.

Nice-to-Haves

• Experience at a bank or issuer with a commercial/business card program (supplier enablement, merchant services, or similar), where you've seen this motion run at scale.
• Deep AI fluency: you've used or built AI/agentic workflows to automate operational work and you're eager to apply that here.
• Startup or founder experience, ideally at an early-stage or AI-native company, bringing speed and scrappiness.
• Exposure to a high-growth tech or fintech environment where you navigated a high level of cross-functional complexity.
