About the Role

Fireworks AI is looking for a Billing Operations Analyst to own billing and receivables operations for usage-based customer business.

AI infrastructure creates a uniquely data-intensive billing environment. This role will sit at the intersection of Finance Operations, Product, Engineering, Data, and Revenue Accounting to help ensure that customer usage flows completely and accurately through billing and ultimately into accounts receivable and cash.

This is an ideal role for someone who combines strong billing fundamentals with systems thinking, data analysis, and a passion for automation.

What You'll Do

Own operational billing processes for usage-based customers.
Manage customer billing setup and ensure billing configurations, payment requirements, and account information are complete and accurate.
Monitor the usage-to-bill lifecycle and help ensure customer usage is captured, rated, and billed completely and accurately.
Perform usage-to-billing reconciliations and investigate discrepancies between source usage data and customer invoices.
Monitor billing exceptions, failed billing events, unusual transactions, and other anomalies.
Partner with Product, Engineering, Data, and Finance Systems teams to investigate and resolve systemic billing issues.
Manage receivables, aging, collections, unapplied cash, and customer account exceptions.
Investigate customer billing disputes and drive issues through timely resolution.
Support month-end close, including billing completeness, AR reconciliations, usage reconciliations, and aging validation.
Execute SOX and O2C controls and maintain appropriate documentation, evidence, and segregation of duties.
Develop exception-based monitoring and controls that allow billing operations to scale without proportional increases in manual effort.
Identify automation opportunities across usage validation, billing, collections, reconciliation, and reporting.
Define and monitor operational metrics, including billing completeness, billing accuracy, failed billing, exception rates, aging, DSO, disputes, and unapplied cash.

What We're Looking For

3–6+ years of experience in Billing Operations, Order-to-Cash, Finance Operations, Accounts Receivable, or a related function.
Experience with usage-based, consumption-based, SaaS, cloud, infrastructure, API, or other high-volume billing models is strongly preferred.
Strong analytical skills and comfort working with large or complex billing datasets.
Ability to investigate discrepancies across multiple systems and identify root causes.
Strong understanding of billing, AR, reconciliation, and financial control concepts.
Experience with SOX controls or operating in a controlled financial environment is preferred.
Experience with ERP, billing, payment, CRM, and data/reporting tools.
SQL or similar data-analysis experience is a plus.
Ability to communicate effectively across both Finance and technical teams.
Strong automation and process-improvement mindset.

What Success Looks Like

You help build a highly automated and scalable usage-to-cash engine for Fireworks AI. Usage is translated into accurate customer bills, exceptions are identified before they become material problems, receivables are actively managed, and Finance has confidence in the completeness and accuracy of PAYG billing as transaction volumes grow.
