We’re looking for a Business Systems Analyst – Billing & Revenue Systems to join our Engineering organization and work closely with the Commerce Platform and Business Systems teams. You’ll focus on the systems and processes that power Aircall’s revenue flows—primarily Salesforce, CPQ, and our billing and integration stack (e.g. Celigo, Netsuite, ZAB (Zone Advance Billing) and related tools).

You’ll partner daily with Finance, Rev Ops, Sales, Customer Success, and Engineering to troubleshoot issues, implement changes, and improve the quality and reliability of our commercial data and workflows.

• Support day‑to‑day operations across Salesforce, CPQ and billing integrations
  : investigate data and process issues, run impact analysis, and propose pragmatic fixes that keep customers correctly billed and contracts correctly represented.

• Contribute to rollout of pricing and packaging changes (e.g. new SKUs, updated bundles, new countries/regions): update configuration, run validation checks in sandboxes, support UAT, and ensure changes are correctly reflected in downstream systems and invoices.
• Document processes and changes in a structured way (Confluence, internal docs, runbooks) so Support, Sales, and Finance teams can self‑serve, and engineering has a reliable history of decisions and implementation details.
• Support training and enablement for GTM and Finance users on new or updated processes (e.g. how to handle early renewals, how specific CPQ flows work, how to avoid common…
