Senior Procurement Business Partner - Mercury

Mercury is building a complete finance stack for startups. At Mercury, procurement is a strategic function. We have a modern approach where teams move fast and procurement provides the structure, systems, and commercial rigor that make that speed sustainable.

We’re growing our procurement team and hiring a Senior Procurement Business Partner to own high-impact deals and help scale how procurement operates. This role sits at the center of procurement execution, vendor operations, and P2P systems. You’ll run procure-to-pay workflows end to end, manage procurement tooling, and partner closely with Finance, Legal, Security, and Compliance to enable smart buying decisions across the company.

What You'll Do

• Own procurement intake and deal execution from request through contract signature and supplier onboarding.
• Design and improve procurement processes, policies, and controls as the company pursues bank charter readiness.
• Act as a force multiplier for the team, setting playbooks and standards others can run.
• Lead contract negotiations end to end, including commercial strategy by coordinating redlines, pricing discussions, and vendor communications.
• Operate and administer P2P and procurement tools, ensuring workflows, controls, and integrations are working as intended.
• Maintain clean, accurate procurement and vendor data across intake, approvals, renewals, and systems.
• Manage day-to-day vendor portfolio operations including vendor records, renewal calendars, pricing changes, SLAs, and basic performance tracking.
• Serve as the operational point of contact for Accounts Payable, Legal, Security, and Compliance on procurement-related matters.
• Monitor cycle times and bottlenecks, and drive process and tooling improvements to increase speed and quality.
• Support vendor risk intake by triggering required cross-functional reviews and escalating issues when appropriate.
• Build and maintain dashboards and reports on spend, renewals, throughput, and savings to support planning and decision-making.
• Partner with the Procurement Lead on reporting, deal preparation, and executive updates.

What We're Looking For

• 5-8 years of experience in procurement, sourcing, P2P operations, or a related finance or operations role.
• Hands-on experience with P2P or procurement systems such as Zip, Coupa, Ariba, or similar tools.
• Track record of independently leading negotiations with meaningful commercial outcomes.
• Experience building or materially improving procurement processes.
• Experience in vendor risk, compliance, or third-party review processes.
• Experience running workflows from incomplete or messy intake through execution and close.
• Strong operational judgment, attention to detail, and a bias to action.
• Comfort working cross-functionally with Finance, Legal, Security, and business stakeholders.
• Ability to work with data and build simple, useful dashboards to inform decisions.

Nice to Have

• Experience operating in a regulated or high-scrutiny environment.
• Experience in a high-growth tech or startup environment.
