Job description

Mid-Senior QA Engineer (Hardware Testing)

3 To 7 Years

Full-Time

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
• 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: Strong expertise testing software that interfaces with physical peripherals (e.g., credit card readers/POS terminals, receipt printers, scanners, or kiosk
• 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 traces to pinpoint root causes.

Core Competencies & Cultural Fit

• Self-Motivated Learner: Curious about low-level systems, eager to understand complex hardware specs, and proactive in expanding technical skills.
• Strong Individual Contributor: Able to take ownership of hardware test setups, ask critical architectural questions, and execute test cycles independently.
• Reliable Team Player: Values transparent communication, acts as a quality advocate, and collaborates smoothly with backend developers and operations teams.
• Remote-Ready Communicator: Clear, precise, and prompt communication across chat tools (Slack, Teams) and project management systems (Jira, Azure DevOps).

Preferred / "Nice-to-Have" Qualifications

• Experience testing self-service kiosk, Point-of-Sale (POS), or transaction processing systems.
• Familiarity with hardware communication interfaces (Serial/COM, USB, HID, TCP/IP sockets).
• Exposure to mocking or simulating physical hardware interfaces for automated test runs.
• AI-Assisted Quality Engineering: Experience using AI tools (e.g., GitHub Copilot, Claude, Cursor) to generate edge-case test data, draft test scripts, and parse complex log output faster.
