A core part of Zum's mission is accelerating the transition to clean transportation by deploying electric vehicles for student transit. The company has committed to electrifying its fleet and has partnered with school districts and utilities to introduce electric school buses, reducing greenhouse gas emissions and improving air quality for children and communities. Zum positions itself as a leader in sustainable student mobility, aligning fleet electrification with broader climate goals. What makes Zum unique is its integrated approach combining a managed services model with proprietary technology and a growing electric vehicle fleet. Rather than simply selling software, Zum takes on the full operational responsibility of running transportation programs for school districts, making it easier for districts to transition to greener, more efficient systems without the burden of fleet ownership or logistics management.

About Zūm:

Who You Are:

The role will report into our Revenue Operations team. This detail-oriented and highly analytical professional will build and maintain the spreadsheet-based models that power our accounts receivable and invoicing accuracy process. The Senior Business Operations Analyst will work hands-on in the data — using complex spreadsheet formulas, pivot tables, and automation tools to identify invoice discrepancies, reconcile billing errors, and ensure accurate, timely collections. While the core focus is on the accuracy and integrity of the underlying data, this role does involve some customer-facing interaction — including light, indirect negotiation to resolve billing discrepancies — along with regular exposure to Location Managers and leadership as part of partnering cross-functionally to resolve issues at the source.

This hybrid position is based in the corporate office in Redwood Shores, CA and requires 3 in-office days per week (Monday, Tuesday, Thursday). Only local candidates will be considered.
