OnePay is a consumer fintech platform offering banking, high-yield savings, credit cards, point-of-sale lending, investing, and crypto services. Backed by Walmart and Ribbit Capital, the company is scaling rapidly to serve millions of Americans and embedded financial services to employees and frontline workers.
As Procurement & Sourcing Manager, you will lead vendor negotiations and manage commercial outcomes on technology spend, including cloud, AI/LLM, data, security, and SaaS vendors. This is a cross-functional role critical to OnePay's growth trajectory.
Key responsibilities:
- Lead end-to-end negotiations on new vendor engagements and renewals, from benchmarking and walk-away positions through final terms
- Structure deals beyond price: renewal uplift caps, usage and true-up mechanics, ramp schedules, termination rights, and auto-renewal protections
- Run competitive sourcing processes and build business cases for vendor selection and consolidation
- Build and share repeatable AI-assisted sourcing workflows (proposal comparison, price benchmarking, contract redlining, negotiation prep) to accelerate team velocity
- Partner with Operations, Finance, Legal, IT, and InfoSec teams to evaluate vendors and structure commercial terms
- Serve as primary point of contact for vendors on contractual matters and escalation point for internal employees communicating with vendor sales
- Drive timely review and approval of procurement requests with alignment across key stakeholders, including C-suite
You will use AI daily as a core tool for benchmarking, proposal analysis, contract review, and negotiation preparation. The role operates in a fast-moving, mission-driven culture where you are expected to be a self-starter, builder, and executor.
REQUIREMENTS:
- 3+ years of strategic sourcing or direct vendor negotiation experience, ideally in high-growth tech or fintech
- Self-starter who identifies problems and brings solutions; comfortable leading initiatives end-to-end without waiting for instructions
- Ability to work cross-functionally with senior management and creatively meet partner requirements without blocking innovation
- Strong negotiation track record on six- and seven-figure software, SaaS, or cloud agreements; demonstrated ability to secure terms beyond price
- Understanding of commercial contract terms (MSAs, order forms, DPAs, SOWs, licensing models) and comfort marking them up with Legal
- Hands-on AI fluency: already using AI tools such as LLM assistants and agents
- Drive and proactivity; builder and executor mindset
