Lead the migration to the next generation of our billing system with no revenue loss or downtime
Define observability and quality metrics for billing correctness, freshness, and throughput
Ensure billing systems meet audit and compliance requirements (SOX, financial audit)

Hands-on experience with usage-based / metered billing: rating, aggregation, and proration logic
Hands-on experience with subscription / recurring billing alongside usage-based models
Hands-on experience with prepaid credits / wallet systems and auto top-up mechanics
Hands-on experience with enterprise / contract billing: custom pricing and negotiated terms
