Fireworks is a Series D AI infrastructure platform (valued at $17.5B) backed by AMD, NVIDIA, Sequoia, and others. The company enables enterprises to build, train, and serve AI models tailored to their data and workflows.
You will own billing and receivables operations for Fireworks' usage-based customer business. This role sits at the intersection of Finance Operations, Product, Engineering, Data, and Revenue Accounting, ensuring customer usage flows completely and accurately through billing into accounts receivable and cash.
Key responsibilities:
- Own operational billing processes for usage-based customers, including setup, configuration, and account accuracy
- Monitor the usage-to-bill lifecycle; ensure usage is captured, rated, and billed completely and accurately
- Perform usage-to-billing reconciliations and investigate discrepancies between source data and invoices
- Monitor billing exceptions, failed events, unusual transactions, and anomalies
- Partner with Product, Engineering, Data, and Finance Systems teams to resolve systemic billing issues
- Manage receivables, aging, collections, unapplied cash, and customer account exceptions
- Investigate and resolve customer billing disputes
- Support month-end close including billing completeness, AR reconciliations, usage reconciliations, and aging validation
- Execute SOX and Order-to-Cash controls; maintain documentation and segregation of duties
- Develop exception-based monitoring and controls to scale billing operations without proportional manual effort increases
- Identify automation opportunities across usage validation, billing, collections, reconciliation, and reporting
- Define and monitor operational metrics: billing completeness, accuracy, failed billing, exception rates, aging, DSO, disputes, unapplied cash
You will help build a highly automated, scalable usage-to-cash engine where usage translates into accurate bills, exceptions are caught early, receivables are actively managed, and Finance has confidence in billing accuracy as transaction volumes grow.
REQUIREMENTS:
- 3–6+ years of experience in Billing Operations, Order-to-Cash, Finance Operations, Accounts Receivable, or related function
- Experience with usage-based, consumption-based, SaaS, cloud, infrastructure, API, or high-volume billing models (strongly preferred)
- Strong analytical skills and comfort 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 controlled financial environments (preferred)
- Experience with ERP, billing, payment, CRM, and data/reporting tools
- SQL or similar data-analysis experience (a plus)
- Ability to communicate effectively across Finance and technical teams
- Strong automation and process-improvement mindset
