Summary

We're looking for a Senior Revenue Accountant to join our Finance team. This role is designed for someone who brings deep expertise in subscription billing, a foundational understanding of revenue accounting principles, the systems fluency to navigate complexity and build scalable solutions, and a genuine appetite for applying AI to make billing smarter and faster.

Billing is the heartbeat of this role as you'll own the full billing lifecycle, serve as the internal expert on Zuora, and be a trusted partner to both customers and cross-functional teams. Alongside that, you'll bring enough revenue accounting knowledge to support month-end close activities, assist with revenue recognition questions, and ensure billing practices are aligned with accounting requirements. And you'll be an active driver of AI adoption using intelligent tooling to reduce manual work, surface anomalies faster, and help the finance team operate at a higher level as we scale.

This is a fully remote position open to candidates based in the United States. We offer competitive compensation, benefits, and meaningful opportunities for professional growth. If you're a self-starter who takes ownership and thrives on solving hard problems, we encourage you to apply!
