Water4 is headquartered in Oklahoma City. Our mission is treated water piped to every home and community, always. Water4 builds, owns, and operates NUMA, a family of water utilities that deliver treated, piped water to homes, schools, and health facilities across Ghana, Sierra Leone, Uganda, and Zambia. Charitable gifts fund the infrastructure, and each business covers its operations and maintenance through water sales and reinvests its earnings in expansion. As of June 2026, NUMA provides access to treated, piped water for more than 1.3 million people and employs over 1,900 people locally, and all five NUMA businesses finished the fiscal year profitable. Alongside this work, Water4's Multiply movement shares the Living Water through Discovery Bible Study groups in the communities NUMA serves.

The Accounts Payable & Finance Specialist is responsible for the accurate and timely processing of Water4's payables and for maintaining the integrity of expense coding across the organization's general ledger. Reporting to the Director of Finance, this position manages the full accounts payable cycle in Sage Intacct, administers the Ramp corporate card platform, and ensures that every transaction is coded correctly by account, department, program, grant, and entity in accordance with Water4's chart of accounts and funder restrictions. The Specialist also serves as a connection point between Finance and Development, reconciling gift and payment activity between Salesforce and Sage Intacct and maintaining accurate documentation of grant agreements, contracts, and payment records. In addition, this position provides front-desk and administrative support that keeps the Oklahoma City office running day to day. Water4 leadership retains final approval authority over invoices and payment release; this position is not an authorized bank signer and does not release payments.
