Job Description

The company is a provider-side iGaming observability and revenue intelligence platform that sits between game providers and their operator distribution network. The platform ingests round-event data in real time, independently computes Gross Gaming Revenue (GGR), and continuously reconciles operator-reported settlements to detect revenue leakage — a problem that costs game providers millions annually in undetected FX errors, revenue-share miscalculations, and bonus misclassifications.
