Key Responsibilities

Hardware & Peripheral Testing: Design, execute, and maintain test scenarios for physical

hardware components, peripheral drivers, and low-level system services.

System & Service Validation: Validate backend services, system daemons, and background

workers under various physical conditions (e.g., paper out, card reader timeouts, hardware

disconnects, power cycles).

API & Service Automation: Build and expand test automation suites for backend APIs, hardware

abstraction layers, and IPC/socket channels using modern automation and mock tools.

Defect Lifecycle Management: Identify, log, prioritize, and track hardware, driver, and service

defects with precise system logs, peripheral state data, and reproduction steps in Jira or Azure

DevOps.

Compliance & Transaction Verification: Test transaction workflows to ensure strict adherence to

security protocols, data integrity, and industry standards (e.g., PCI compliance).

Cross-Functional Collaboration: Partner directly with backend .NET engineers and technical

operations to debug edge-case hardware faults,



refine acceptance criteria, and ensure reliable

releases.

Required Qualifications & Technical Skills

Experience: 4+ years of professional quality assurance experience, with direct experience testing

software integrated with physical devices, hardware, or external peripherals.

Hardware & Systems Testing: Solid expertise testing software that interfaces with physical

peripherals (e.g., credit card readers/POS terminals, receipt printers, scanners, or kiosk

components).

API & Backend Testing: Solid proficiency in testing RESTful APIs, backend services, and

asynchronous processes using tools like Postman, Swagger, or custom CLI harnesses.

Test Automation: Hands-on experience developing automated integration or API test suites using

tools like Playwright, Selenium, C#, or Python.

Tooling & Logs: Expertise in analyzing system logs, Windows Event Logs, and device diagnostic
