Key Roles & Responsibilities

• Design and execute system-level test strategies for Linux-based IoT, connected instrument platforms, and flagship Windows desktop applications (such as TRIOS).
• Perform manual and automated software testing specifically targeting complex Windows desktop environments and scientific applications.
• Validate end-to-end workflows across device firmware, edge services, backend APIs, web UIs, and desktop clients.
• Perform functional, integration, regression, performance, and reliability testing across the entire software ecosystem.
• Test system behaviours under real-world conditions (network latency, device failures, power cycling, upgrades, stress scenarios).

Hardware–Software Integration

• Test instrument bring-up, initialization, calibration, and recovery across firmware updates and fault conditions.
• Validate operation under environmental and operational stress (temperature, vibration, long-duration runs).
• Lead and support cross-disciplinary root cause analysis involving desktop software, firmware, electronics, and mechanical subsystems.
• Use logs, telemetry, and lab tools (e.g., multimeter, oscilloscope, logic analyzer) to diagnose complex system issues.

Automation & CI/CD (System & Desktop Focus)

• Develop and maintain automated tests at the system, API, web, and desktop application layers (Python strongly preferred; C# or UI automation tools a plus).
• Integrate automated tests for both embedded Linux systems and Windows desktop applications into CI/CD pipelines to support continuous quality and release readiness.
• Collaborate with DevOps and development teams on build verification, deployment validation, and pre‑production testing.

Manufacturing & Field Support (Collaboration-Oriented)

• Support manufacturing and service teams by validating system-level test coverage and diagnostics.
• Reproduce field and manufacturing issues in lab environments and help drive corrective actions.

Education

• Bachelor’s Degree in computer science or computer engineering preferred, or an equivalent combination of education, training, and experience.

Experience

• 5+ years of experience in system testing, validation, or quality engineering for complex products.
• Experience with manual and automated software testing for Windows desktop-based applications (e.g., TRIOS or similar complex analytical/instrumentation software).
• Hands-on experience with Linux-based systems, embedded platforms, or IoT devices.
• Proven ability to validate end-to-end systems spanning hardware and software.
• Experience with test automation and scripting (Python strongly preferred).
• Strong troubleshooting and root cause analysis skills across hardware–software boundaries.
• Comfort working in a lab environment with physical devices or instruments.

Preferred

• Interest or foundational experience working in an analytical instrumentation domain.
• Basic knowledge of Networking and TCP/IP communication.
• Interest in interfacing with embedded devices.
• Experience testing web applications, APIs, and backend services.
• Experience with desktop UI automation frameworks (e.g., WinAppDriver, TestComplete, Selenium).
• CI/CD pipeline integration (Jenkins, GitHub Actions, GitLab CI, Azure DevOps).
• Docker or containerized deployments.
• Exposure to cloud-connected systems (AWS, Azure, or GCP).
• Performance, reliability, or long-duration system testing.
• Observability tools (logs, metrics, traces).
