QA Lead - Enterprise POS & Sales Management Systems

About the Role
We are looking for a hands-on QA Lead to own the quality strategy for our enterprise Point-of-Sale (POS) and sales management platforms. These systems process live retail and F&B transactions across hundreds of terminals and multiple store locations, integrating with payment gateways, loyalty/CRM, inventory, and back-office reconciliation. You will set the testing direction, lead a team of QA engineers, and be the final quality gate before releases reach production.

This is a leadership role with real technical depth - you will still get into test design, automation frameworks, and difficult defects, while mentoring the team and working closely with development, project management, and client stakeholders.

Key Responsibilities
. Own the end-to-end QA strategy, test plans, and release criteria for enterprise POS and sales management systems.

. Lead, mentor, and manage a team of QA engineers - allocating work, reviewing test coverage, and growing the team's capability.

. Design and oversee functional, integration, regression, performance, and UAT testing across POS terminals, back-office, and connected services.

. Drive test automation - establish and maintain automation frameworks for UI, API, and mobile POS, and lift the ratio of automated coverage over time.

. Validate transaction-critical flows: payments (EMV/contactless), refunds, voids, discounts and promotions, tax, tender types, and end-of-day reconciliation.

. Verify hardware and peripheral integration (card readers, receipt printers, scanners, cash drawers) and online/offline sync behaviour.

. Own defect management - triage, prioritise, track to closure, and report quality metrics to delivery leads and clients.

. Coordinate integration and end-to-end testing with third-party systems (payment providers, ERP, loyalty/CRM, inventory, middleware).

. Plan and execute performance and load testing for peak trading conditions.

. Support UAT with clients and manage go-live readiness, including production verification and rollback validation.

. Champion QA best practices, embed quality early in the SDLC, and contribute to CI/CD pipeline quality gates.

Required Qualifications
. Minimum 7 years of QA / software testing experience , with a strong track record on enterprise-grade transactional systems.

. Proven experience leading a QA team - allocating work, mentoring, and being accountable for a team's output and quality.

. Domain background in POS, retail, payments, or sales management systems (or closely comparable transaction-heavy platforms).

. Solid understanding of the full QA lifecycle: test strategy, planning, estimation, execution, defect management, and reporting.

. Hands-on experience with test automation tools (e.g. Selenium, Cypress, Playwright, Appium) and API testing (e.g. Postman, REST Assured).

. Experience with test management tooling (e.g. Jira, Zephyr, TestRail, Xray) and defect tracking.

. Working knowledge of CI/CD pipelines and integrating automated tests into build and release flows.

. Strong understanding of integration testing across systems and services (payments, CRM/loyalty, inventory, middleware/APIs).

. Excellent communication skills - able to work with developers, project managers, and non-technical client stakeholders.

. Fluent in both English and Chinese - able to work across English and Chinese-speaking teams, clients, and documentation.

Preferred / Nice to Have
. Experience with payment certification and PCI-DSS-relevant testing.

. Performance and load testing experience (e.g. JMeter, k6, Gatling).

. Exposure to cloud-hosted systems (AWS, Azure, or similar) and microservices/API architectures.

. Experience testing mobile and tablet-based POS deployments.

. ISTQB or equivalent QA certification.

. Prior experience in a system integration or enterprise delivery environment.

What Success Looks Like
. Releases ship on schedule with a low and falling defect-escape rate to production.

. A measurable, growing base of automated regression coverage.

. Clear, trusted quality reporting that delivery leads and clients rely on for go-live decisions.

. A capable, well-mentored QA team that scales with the project portfolio.
