QA Lead (Billing & Revenue Assurance)

We are looking for an experienced Lead QA Engineer to own quality for the Net2Phone billing platform. We are building a billing system where every invoice is provably correctly rated, taxed, prorated, reconciled and where the team can defend that claim with documented coverage rather than assumptions. You will focus on testing billing correctness end-to-end: how a call becomes a rated record and then an invoice line, where usage gets lost or double-counted between the switch and the bill, how proration behaves when a customer changes plans mid-cycle, and how a third-party tax engine's output is verified when you can't inspect it. You are equally skilled in leading a team: setting the documentation standard, acting as the intake gatekeeper with Product, and deciding where automation effort yields true value. This is a manual-testing-heavy position: automation leadership here means planning, prioritization, and coverage governance, not day-to-day framework development. You will not be the primary implementer, but you will be expected to read, review, and debug the team's suites.   PLEASE SUBMIT CV IN ENGLISH. ONLY ACCEPTING CANDIDATES FROM LATAM. ADVANCED SPOKEN ENGLISH IS REQUIRED.
