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.

• Act as an active member of a Scrum team, participating fully in all agile ceremonies and maintaining all related artifacts.

• Own the test strategy for billing: Covering rating, mediation, invoicing, taxation, payments, credits, adjustments, dunning, and reseller/white-label billing hierarchies.

• Design and document test coverage for month-end billing cycles, including cutoff and timezone boundaries, reruns, partial failures, and retry safety.

• Perform revenue-assurance testing: Reconciling CDR volumes against invoiced amounts and quantifying the financial impact of any discrepancies.

• Trace billing discrepancies to their root cause: Distinguishing rating-engine defects from mediation or switch-side issues, including reading SIP traces or packet captures when necessary.

• Enforce the requirement intake gate: Ensuring no user story enters a sprint without testable acceptance criteria.

• Set and enforce documentation standards: Ensuring requirement-to-test-case traceability and reviewable per-epic coverage.

• Drive the automation roadmap: Deciding what gets automated, in what order, and with what expected ROI, while conducting code and test reviews for the resulting suites.

• Establish and report billing quality metrics: Defect escape rate, coverage, defect density, and release readiness.

• Mentor billing QA engineers and provide clear technical direction.

• Communicate and escalate product quality risks: Holding ground when supported by data.

• Python & Pytest: For service and integration automation.

• Playwright: For UI automation.

• SQL: For billing and rating data validation—this is a daily tool in this role, not an occasional one.

• Allure TestOps: As our Test Management System (TMS). Automated test cases are linked to TMS cases, and we expect QA to extend coverage directly within it.

• Jira: For project management and defect tracking.

• GitHub Actions (GHA) & Jenkins: For CI/CD, leveraging shared pipeline libraries.

• Grafana: For monitoring quality and delivery metrics, including defect escape rate.

• Third-Party Tax Engine: For telecom tax and regulatory fee calculations.

We are always open to adopting any reasonable tool that drives higher quality into the product.
