12h•Hybrid

About The Position

This is a foundational hire on a newly formed in-house team, owning the procure-to-pay cycle end to end. Payables span GPU and server purchases, colocation and power agreements, network capacity, and a fast-growing operating expense base across multiple sites and states. The accuracy of what you record flows directly into the fixed asset base, cost of revenue and our financial statements. The role includes designing the process, not inheriting it.

4+ years of accounting experience with substantial ownership of the AP or procure-to-pay cycle
Bachelor's degree in Accounting, Finance, or a related field
Experience with purchase orders, 3-way matching, and receiving discipline in an environment with meaningful physical goods or capital spend
Solid understanding of accrual accounting and month-end close, including the judgment required to build a complete accrual with imperfect information
High-volume, high-dollar payment experience with a control mindset
Comfort operating without an established process and building documentation as you go

Nice To Haves

Data center, infrastructure, hardware, manufacturing, or construction industry background
Working knowledge of fixed asset accounting and capitalization policy

Prepare audit-ready support and respond to auditor requests on payables, accruals, and search for unrecorded liabilities
Administer reimbursement and corporate card programs on Ramp, including receipt and policy compliance review
