We're looking for an exceptional Utilities Billing Engineer (Sviluppatore Esperto di Fatturazione Luce e Gas): a rare hybrid who has both built billing systems with their own hands and lives and breathes the domain of energy invoicing. This is not a generic backend role and not a generic functional role. We want someone who has already designed, coded, and shipped billing engines for the electricity and gas market, who understands every line of an energy bill down to the last decimal, and who can turn ARERA regulation into production code without a translation layer in between. You will be the technical and domain backbone of our proprietary ERP, owning the engine that issues invoices in the utilities (gas and power / luce e gas) sector from concept to completion.
KEY RESPONSIBILITIES
Architect, develop, and own the billing engine of our proprietary ERP, end to end, from data model to issued invoice.
Translate market rules and ARERA regulation directly into clean, tested, production-grade code with no functional handoff required.




Design the rating and billing logic for electricity and gas: energy spend, transport and meter management (trasporto e gestione del contatore), system charges (oneri di sistema), taxes, excise duties (accise), and VAT.
Model complex tariff structures, regulatory components, and customer segments, and implement them so they scale to high invoicing volumes.
Build and optimize the data pipelines that turn metering data (curve di carico, consumi, EDM) into correct invoices.
Implement robust validation, reconciliation, and anomaly-detection layers over billing runs, and resolve discrepancies at the root cause.
Design REST APIs and integrations between the billing engine, market flows (SII), and the rest of the ERP.
Set the engineering standard: code reviews, automated testing of billing scenarios, and documentation that makes the engine maintainable.
Partner with operations, administration, and compliance, acting as the single source of truth on
